Post by: PropMan on January 09, 2015, 11:02:28 AM
Got it from Clark's Hardwoods in Houston. They have a limited supply and are considering discontinuing the Spruce. Apparently the only people who buy it are plane builders. I bought enough for two sets of wings ;-)

Yeah, Christmas is Great!

It's amazing how easy it is to buy stuff when you're way out in the country. Even easier when you're down with a cold.

I'll make it to Oshkosh, but probably not the Eagle. I hope to fly the Eagle to Reklaw thou. We'll see.

Any chance we could get your weights on front and rear spars only, just like you showed?   I even would be interested to know how close they are from side to side?

Good going Frank!

Title: Re: Frank's XL
Post by: PropMan on January 31, 2015, 11:28:13 AM
Ok, got the 10 deg cut on the top of front spars, sanded and scraped excess glue off. weighed all 4.
                       L             R
Front spars- 6.86lbs    6.57
Rear           - 5.14        5.41
total           - 12.00lbs 11.98lbs

Boy I got lucky. cant get much closer, but interesting how much difference(around .30lbs) in the pairs.

Keep in mind my XL is more of a Medium. I've reduced the span from 154" to 138" per. this gives a LEU span with XL size caps. so these will be a bit lighter than common XL spars.

Excellent Frank, 
  Can’t ask for anything more or better on how you did your measurements or the accuracy in which you did so. Outstanding!   It is calculations like these that allow progress in any type of build.  In this case, are we pretty consistent from side to side- A sound YES.

thanks

Title: Re: Frank's XL
Post by: PropMan on February 14, 2015, 05:50:09 PM
One more tonight :)
I decided to build a gas tank from aluminum with proseal and rivets. Not quite sure how it will work out yet but I decided to attach it by making the top of the tank form the top wing at the inboard wing bay. There were mods done to the ribs to accept screws for attachment and to reinforce for fabric. basically doubled the ribs inboard one bay. If all goes according to plans(Yeah Right) i'll be able to drop in the tank and screw it down on the top of the wing after fabric. The extra parts were weighed before installation and this adds 0.40lbs. the tank has been drawn out on paper and best guess, some math included, it'll be 3+lbs. In the event i have to go and get an N number each wing will be built to accommodate a tank.

Hey Hugh,
You got it all wrong. 8)   I have AC and heat in the shop. It's a toasty 67 degrees inside today while the wind is blowin 25kts and 35 deg outside.

But i can say wont be any welding in there, sawdust gets knee deep when im cuttin a big prop. Plannin on starting the fuse in the hanger by April when the weather is perfect!

Hey Everyone,
Getting back on the XL, going to be a bit long winded on this one. 

First. shortly after my last post to this thread my Mother had a terrible life changing event, won't go any further into that other than to say I dropped everything for a couple months to help my parents. Been a slow recovery but it is one.

My prop business was set back on order deliveries and i apologize for that to a point. For me Family is at the top of my priorities. Fortunately All my customers understand that and I am blessed all the more for it. 

NOW, Back to the XL.
It's gone thru a few changes also. The biggest is the power plant choice has been changed from the 4A084 to a Verner  Scarlett 3VW. This means drastic weight reduction. This of coarse means the tail will be per plans instead of the heavier 4130 planned to compensate for the heavy engine. I have started the second wing this week and expect the engine as soon as next week. It should be test run by now. I'm also attempting to video the second wings construction with a Gopro in time lapse, not promising any good results, it my fist attempt . 
More later.
Frank

Frank,

Is the little toothpick the Scarlett prop? I was thinking it would run a larger diameter prop than the halves. Don't they just turn it ~2500rpm for max power?

Have you gotten an official weight on yours yet. It's light enough to pick up and step on the scales with.

It does look like a super LE engine!

Hugh
Title: Re: Frank's XL
Post by: ParQld on January 15, 2016, 04:02:32 PM
@sciguy, it is the larger one. Check to 2 photos of the props against the one on the new engine. It rotates anti clockwise, so therefore is the larger one. The Smaller one would be for the VW based engine.

am i right Frank ?

cheers Paul

Paul,

That's a keen eye there. I was thrown by the larger prop lacking holes and then the one pictured on the Scarlett being drilled. I was really hoping that it was the bigger one.

Hugh
Title: Re: Frank's XL
Post by: PropMan on January 15, 2016, 04:21:41 PM
Yeah, sorry i didn't clarify that. The S3VW turns clockwise(sittin in the seat view) Yes, much larger prop compared to the 1/2. Almost twice the blade area of the 1/2 also. this first prop is 62x36, the diameter is limited by ground clearance. but could go larger if we weren't worried about trimming it inadvertently.
 82lbs with starter assembly and generator. close to 70 without those conveniences. 
it'll be interesting to see the ROC will be, max torque is 2100-2200- rpm and 38-39 hp. :-)

If this engine proves as dependable and durable as we hope,  I wonder if we might see a new generation of LEs with somewhat taller gear to accommodate an even more ideal prop diameter? More air moving slower is way more efficient for these 103 birds let alone more comfortable on the pilot. I suspect that the ROC will be like a heart sick angel:)

Hugh
Title: Re: Frank's XL
Post by: PropMan on January 16, 2016, 05:22:56 AM
Yes indeed, we are only talking about a few inches. Depending on how testing goes I think optimal diameter is 64-68". May even be able to just mount larger diameter tires.

I have been looking at getting back into the Ultralight realm for a while now and the XL is on my short list. This combination may just put it over the top. Looking good Frank, are you going to have one of these motors on display at Airventure ?

Title: Re: Frank's XL

The stroker nicasil aluminum cylinders should make this motor a lead pipe cinch on a lot of ultralight airframes. 

I hope Frank tries these.

I haven't asked but it appears http://www.hummelengines.com/ (http://www.hummelengines.com/) uses someone else besides LN engineering to do their cylinders now.

I noticed they use the term "Nicom"  this may be where he is getting his cylinders.  (http://www.uschrome.com/nicom)

I would try to buy Nickies for my radial 3vw from Scott Casler...  You may want Nicom to treat your piston skirts as well.

I stopped by Franks booth, and the engines and props sure looked good.   I know Frank is in mid-build...so can't show the whole thing together...yet.

but here are some observations:

There were many-many aircraft in the LSA-ultralight range, that were sorta there.  The SD-1 really comes to mind,  once again this has changed hands, and yet, only a partial aircraft displayed, with few looking it over, perhaps much to do with the fact, that this has almost always been shown as a "dream" and hardly ever a complete flying plane after many years.

The BD-6, which was fairly promoted last year, was in fact, no change this year.
The ION- had 5 whole hours flown on it, since last year.
The ICON A5, has started to be the joke of the investing world.  $35 Million later, and still almost NO production But if you have $197,000 plus some 15K for chute money, you might get one, with restrictions. 

I am just picking on some of the really obvious ones, there are many many more. And this of course has gone on easily for the last 15 years.

I commend Steve J. for bringing in his bird...Flying and all.   WELL done.

Do something everyday on it, even just to study the next piece to be worked on... To sand the wings I hung them leading edge up at eye level and used a 220 grit foam core sanding block in each hand... There was a windrow of saw dust on the floor and it went fast... Here the varnishing system I should of used instead of spraying HVLP twice - went way heavy [scroll down to last screen]: http://www.angoraaffaire.com/leu/wings.htm

Frank
How long is it getting?
Perhaps another horrizontal brace @ the mid point. 
Long unsupported tubes fail by buckle. 
And if any tubes are going to get challenged the landing gear is the obvious contender.
Hate to add weight but a consideration.
looks good
I was going to make a tall gear anyway based on comments by Joe Spencer. he likes a greater angle of incidence at 3 point stance.

Post by: PropMan on August 24, 2016, 06:55:04 AM
Tom,

I added 2 inches vertical height, and kept the wheels in same location(for CG) per plans. I also added a horizontal 1/2 inch tube , about 3 inches down from gear attach point. If you compare the LE to XL gear, the XL has larger dia tubes everywhere,

 Doing my best to build light, but life is full of compromises! 

Been looking at 8.00 x 6 tires also, this gives additional height, just dont want to add too much weight. If they need tubes it's a deal killer.
Title: Re: Frank's XL
Post by: scottiniowa on August 24, 2016, 07:42:15 AM
Frank, I think your going to have to go to tubeless ATV tires to save the weight your hoping to.  Dune buggy tires too, that are tubeless.   Might have to set up a  end lathe to shave off the lugs..  (wood bowl lathe) but that works well.

Keep us informed.

What was the best tire you descided on?

can you make a breakdown, size vs weight of the tires, I want to get larger ones but light as possible, the tractor tires may be best solution but just seems heavy, but the 2 ply ones may be a little lighter, about 5lbs each, but sure does add some weight. I'm still searching for the good combination. I know sam and a couple others used the 15x6x6 Carlisle Turf II
Title: Re: Frank's XL
Post by: PropMan on September 06, 2016, 07:42:42 AM
The one currently mounted is the Carlisle turf II. I'll leave them on until i mount the engine and check prop clearance(67" diameter prop). 

The tires that came with the Black max wheel set are 2.2 lbs each. About 12"tall
The Carlisle Turf II are 6.2 lbs mounted(don't have unmounted weight yet). 13.7" Tall mounted
The Carlisle 8.0 x 6 are 8.1 lbs each. 18" tall

Now the Turf II and 8.0 x 6 could easily be reduced in weight by shaving off some tread as Scott mentioned earlier, how much is unknown.

On the prop, By my calculation the 3VWs ideal prop diameter is 67", testing will hopefully confirm this.

With all the extra chord in Leonard's wings, Eagles appear to get aloft pretty quick even with low thrust numbers. That thing is going to jump off the ground with all that thrust...but you knew that.

Title: Re: Frank's XL
Post by: PropMan on September 14, 2016, 09:03:54 PM
Bob- the Scarlett is actually the same weight as the lightest 1/2 VW, and thats with a starter!

Darren-i set the axles at 0 camber an 0 toe when welding it all together. Then realized when i bolt on the engine and wings, and put my but in there, things may go negative. So i made shorter cross tubes(5/8" shorter). Looks like i have 1 degree positive. outta work out now.

Joe- bought the tires from Amazon, the'er Carlisle turf saver II, 6.2 lbs mounted with hubs and 13.7" tall. gonna run them and see how it all shakes out before going taller. hate to add 10 lbs just for taller tires.

Haven't worked on the Eagle much lately, had a hog problem, they are tearing up my pasture an gettin close to the runway.

I have mounted the seat and test fit the seat belt i bought. I'll be returning the seat belt, ordered the wrong one, it's way too heavy.

The seat is the plans standard but i used solid rivets and the outer strips are .020 and 1.5" wide, also used plate nuts instead of washers and lock nuts. all these items were chosen cuz i had them.

Title: Re: Frank's XL
Post by: Vince Carucci on October 05, 2016, 02:20:57 PM
I purchased an Aluminum Sheet (http://www.mcmaster.com/#8973k61/=14gw2kn) from McMaster-Carr for $15.59. It's fairly soft but it's priced right and it's corrosion resistant, very easy to work with. I'm afraid I can't comment on shipping cost as I had it sent to my work so shipping was free. While not the strongest aluminum out there, a single 1" wide strip of 0.016" should be able to hold nearly twice my weight. I reason that 8 of them woven together with the 14 cross strips should be strong enough for a seat.

Hey Frank - we are fighting the Hogs here too - just ripping the runway up in several areas - is getting to be a constant battle - trapping is not keeping them down & shooting is just one at a time and you never know when they are going to show.  Good Luck in your battle with them.

What rod material did you use for the "spring"?

Pete, I am not sure what Frank used.  But 17-4PH works well for spring applications.   Perhaps a more interesting question "after" one knows the material,  is

By the way, there are generally three grades of 17-4 PH a person can use... we generally go with the strongest grade for spring application such as this.  

As you may have figured out, my brother and I make springs to order for stinger type aircraft...but what I generally don't do is tell the customer what he needs as the variables are to great.  They tell us, what they want.

$75-$100 gets nearly all the orders covered, up to 16" in length and up to .875" dia.   (far larger than any XL would ever need)  

best of sucess
Title: Re: Frank's XL
Post by: PropMan on March 29, 2017, 05:56:55 AM
Pete- I purchased some 1/2" stainless rod to fit things up till i could research what would be the best material for the actual spring.

Scott- Thanks!! No more research needed. Wish i would have realized you fabricated these, you need to offer tailwheel assemblies for the Eagles.


Time will tell if the 1/2" rod is adequate, with my rather crude testing it seems so. This is the third attempt at a tailwheel that is to my liking. And i'm close, But i think the caster is still too aggressive. More to come

OK, i need to catch this thread up .

So, the fuel tank is near complete. I had started a thread just for the tank, hope it is helpful for others. While waiting on the proseal to cure i started on the oil tank, also in another thread.
And to jump on another part , i formed a battery tray. The battery is 2.75lbs and is a LiFe. not to be confused with the Li Ion. This battery is mush more stable and not prone to create a fireball if overcharged.

I hope the learners on the site realize the fuel tank ends with the fluting pliers technique is the normal method of how one would go about making a set of aluminum ribs

Hydrogen and oxy?

Title: Re: Frank's XL
Post by: PropMan on October 21, 2017, 06:37:24 AM
Verner recommends a tank that has a 5 Liter total capacity, 3 for oil and 2 for air. This tank is a prototype for the three small engines 3VW, 5VW, 5Si. It's a bit large for the 3VW but doesn't look over-sized. We'll see on the oil cooler, my hope is with the aluminium tank and good airflow over it, like an A65 Continental, no oil cooler is needed.

Nice, Frank.  I like the alum transition from the firewall/sides to the windscreen.

Keep the progress going, and get it to flight testing.  We thought we would be flying our Radial Legal Eagle by now, but as I said before, because of too much empty weight, we are getting registration as EAB to be legal.  We have the N number, and have sent in the registration application papers, but aren't optimistic about getting these returned for another month or so, then we need a DAR inspection.

So, if you keep pushing, you can tell us how good the Verner flies!

Thanks fellas. I am certainly looking forward to hearing this thing run. Teaching myself to weld aluminum this week, so I can get the oil tank done and mounted. That's the last item on my list to fabricate.  Then it prime, paint, cover, and reassemble.

Tom, if you are close to a FSDO office, you can get FAA out for the inspection for no fee, out tax dollars at work. Good luck

Frank, we have a FSDO here, but they are not staffed to do inspections.  I have heard of guys locating from Ky to Indiana, just across the river, and they can get the Indianapolis office to do the inspection.  Not practical for us.

Good luck on the alum welding.  Thick stuff is easy, thin takes some finesse.  You can do it.

Well, after 4-6 hours of learning how to adjust the gas and prep the aluminum i was able to weld a flange of 3003 .040 together that looked ok. This helped me realize how much more effort it will take to weld a complete tank!!!
Called a friend, an he was very nice to help me out. Gotta tank on the way.  
So rolled the LE out for some photos before I disassemble,  prime, paint and cover.

 Excellent Frank,
   Just a thought on future welding, by watching and following the "tin man" ways, you should be able to tackle welding of 3003 alum    Another thought is to bend up your tank parts and have a good "tig" man do them.  As most know the labor is in the making of the parts, the gravy time falls on the actual welding process.

Sounds like you really come along well Frank.  Good going!

Very nice work.

One observation on the header tank... are you using a fuel pump or relying on gravity feed?  The reason I ask is, if you are running a fuel pump, the header tank would be more effective mounted in a vertical direction.  In the horizontal direction your fuel pickup is more susceptible to yaw/bank-induced slosh.

I can see that if you are relying on gravity feed it gets harder to go vertical and maintain head pressure which could virtually force the horizontal setup.
And yes I recognize this is only an issue when the header tank is less than 100% full.

Les, the 1/2" tube is oil supply from tank to engine , the tank outlet was a little off and had the rubber hose too close to the cylinder for my comfort so I ran a soft aluminum tube with short rubber hose connected .
The springs were part of a project I picked up for materials but don't have any info on them.

No dynamic balance,  the hi low carb adjustments make a big difference in how smooth it runs. Still have a flat spot when advancing the throttle about mid way. Need to get my instruments straightened out then I can fix that

Tom, what tach are you using? 
Mine is off considerably
Title: Re: Frank's XL
Post by: Tom H on March 07, 2018, 05:26:04 AM
Frank, we have a TinyTach in the radial eagle right now, and it seems to work OK.  I don't know the model number, though.  It is a model that can be set for # sparks/revolution to match a range of engines.  Not too much trouble with it so far, but not too much time on it either.  Had to move the location of the sensing wire on one of the spark plug wires to reduce erratic operation.

However, I did have to try several TinyTachs on DE Stubby to get something that works.  We ended up with a TinyTach (not sure of model) on one of the ignitions, and a TTO Tach on the other ignition.  The TTO Tach worked great at first try - no fiddling around with the sense wire location, smooth display.  As for accuracy, seems correct, agrees with the TinyTach, but have not verified with optical tach or other types.

I have a TinyTach clone in the shop that my son gave me.  He bought a hand-full of them for his lawn cutting equipment, probably a few bucks each, and gave me one.  I have not tried it, but he said they work fine.  I believe others on the Nest may have tried clones, too.

From my experiences, I'd recommend Trail Tech TTO, if you want a digital readout.

I found my write-up from May 2012 on tachs in the old Yahoo groups.  Hope I'm not overly hijacking this thread with it though.  Following in italics is from the old Yahoo group:

Here is an update on our quest for a working tachometer for our DE, and some other related "good" ideas:
 
In the email attached below this one is a description of the Tiny Tachs that we have and tried.
 
Update on the Tiny Tach TT4RX, "Tiny-Tach 4C reset w/ filter" - This is an older version, calibrated for one spark per 2 revolutions, and not adjustable.  After it locked up, I was able to reset it to operation by peeling off the front cover, digging out some rubber, and shorting the terminals.  I think these units lock up if there is too much signal.  Our DE has dual ignition, primary is distributor ignition, secondary is magneto.  We had run our Tiny Tach wire alongside the magneto on/off switch wiring, and I think it may have been overcome with the signal noise from magneto.  As part of the effort, I found someone on the web that ran his TT wire through the grounding braid of a piece of coax that he had removed the inner conductor and its insulator from.  A lot of coax is too tightly constructed to allow this, but I had a piece that I was able to do it.  I worked the TT wire through it.  The TT wire is itself a coax; its inner wire is wrapped around the spark plug wire, and the shield is connected to a ground at the engine.  On the added, outer coax I insulated the engine end, but grounded the panel end of the coax.  Also, I routed the coax away from the magneto wiring.
 
This all seemed to work, and work well, too.  Problem is, this TT model accumulates total time in whole hours.  Not hours/minutes, or hours/tenths of hour.  We wanted to see better accumulated time resolution than whole hours.


A couple of extra tidbits of this older model.  There is a reset button, and it will reset the accumulated time back to zero.  I had made a plastic cover to protect the button to prevent accidental time reset.  I also found that a run signal can be faked into these OLDER models.  Connect the ground wire and the signal wire of the TT to the secondary of a 12 volt, AC transformer (not a DC power supply, has to be AC).  I used this technique to build the run time back up to match our engine run time. 
 
Kiblinger and Spencer came up with a TTO tachometer.  I ordered one and tried it out.  It worked great.  No wandering, steady updates, no lock-up.  It shows accumulated time in hours/tenths of hour, non-resettable.  Immediately after shutting engine down, it shows the max rpm for maybe 10 seconds, then shows the accumulated hours.  It is smaller than the Tiny Tachs, but the display is about the same size.  It has a setting button on the back surface, and can be set for # pulses/crank rotation, fast/slow updates and for high/low sensitivity.  The wire is not a coax, and it does not require a ground connection at the engine, just some wraps around the spark plug wire.  I did take care to route the wire away from the mag wiring, because it could possibly be confused with all that electrical noise.  I like it.  It is a "Trail Tech TTO Tach/Hour Meter 72-A00", ordered from PowerSportSuperStore.com, and it cost $29.65 total.  There are sources a few cents cheaper, but I had purchased from this place previously, so went with them.


Only problem, it had zero time on it, and I wanted it to match the engine time.  During my testing of Tiny Tachs, I found that the newer, settable versions could not be fooled to operate with the 12 VAC transformer trick.  I figured that these newer tachs sense a signal that has a faster transition time than 60 hz.  I had a switching power supply from an old TV digital converter, and thought that there may be some fast transition signal available in there, so I opened it up and tested it with one of the newer model TTs.  Just to be sure not to get any higher DC voltage in the TT, I put a 100 pf capacitor in series with the signal lead, and began touching points of the power supply circuit board.  I found a spot that tricked the TT to operate at about 15,000 rpm and it started accumulating time (Didn't have to connect the ground wire to anything to make the tach work, so I simply connected the ground wire of the TT to the metal work bench (yeah, I know, electricity on a metal bench).  I connected a house light timer to it and set in a dozen hours and let it run.  Next day the TT had the right amount of hours on it.  Problem solved.
 
I tried the same trick on the TTO and it worked, although there is no ground wire to connect to the bench.  So, I was able to set the TTO with the correct engine hours.  We put it in the airplane and have a couple add'l hours on it.
 
The switching power supply is a wall wart, 120vac input, 5 vdc output, 1.72 amps.  I can't guarantee that any other PS will work; may have gotten lucky with this one.  I think what is happening here is that the switching power supply converts 60 hz to maybe a couple thousand hz in the process of making the DC in the output.  I suppose the tachs sense this higher frequency as a spark signal.
 

A previous method I used was to connect a neon transformer (120vac input, approx 5,000 vac output) to a spark plug with spark plug wire, and wrap the TT signal wire around the spark plug wire.  This worked great, but I did not like running the sparking plug unattended for a dozen hours, and it was somewhat cumbersome.
 
The newer TTs, even with the wire run away from the mag wiring, did not operate as smoothly as the TTO.  I still think that the newer TTs can work well in some applications, but may be more sensitive to extraneous electrical noise, causing the display to constantly fluctuate.  Maybe the added outer coax would work.  But, I probably won't be messing any more with them soon.  Gonna try to do some flying.

On our DE, we have a tiny-tach TT2A-O, which we rec'd last Dec.  It is a bit erratic on the plane, but I think that is a problem of finding the right spot on the plug or coil wires and the right number of wraps to get a steady signal.
 
At least I hope so.  This is the third one we've tried.  The first was part #TT2A, description "Tiny-tach adjustable firing mode".  The package card was marked "2A Adjustable".  This unit locked up on the plane.  Steve at Tiny-tach told me how to reset it by peeling off the front cover, and digging out the rubber to the right of the switch botton, then shorting out two traces on the circuit board.  I think what this does is short the internal battery momentarily, allowing the unit to re-start.  We tried to make this unit work, but it kept locking up.
 
Steve then sent us an older, non-adjustable model, shown as part #TT4RX, description of "Tiny-Tach 4C reset w/ filter".  On the back was written "4RX".  The package was marked "TT226R-4cx".  This unit also locked up on the airplane.
 
Then we got the current unit, part #TT2AO", description "Tiny-Tach RPM/HOUR Meter - Adjustable/Filtered".  The package card was marked "2AO".  On the back of the unit was printed "411TT2A", followed by hand-written "10".
 
We have a Tiny-tach on the LEU, older non-adjustable model, and it worked great.  So, we are optimistic that we can get this latest unit working well.

I just talked to Steve at Tiny Tach. What is the model # you're running? TT2A M? Did it come with a coax lead and you have to strip the cover back and solder a pigtail on the end to wrap around the plug wire?
$47.00? That's diff than the one I had...just cut the lead to length and wrap it around the plug wire. Lasted 141 hours. I don't want another one of those. Believe it was a TT2A
