LE / Re: Horizontal Tail Drawing

« Last post by ironnerd on May 30, 2025, 07:38:41 AM »

Okay, after a quick bit of work in a free 2D CAD (LibriCAD)

In the middle we have the original drawing.
On the left we have the CAD version of the Horizontal Tail using the dimensions given in the plans.
On the right we have the CAD version of the Horizontal Tail using dimensions taken from measuring the drawing.

LE / Horizontal Tail Drawing

« Last post by ironnerd on May 28, 2025, 05:07:17 PM »

Is the LEUL Horizontal Tail drawing correct and accurate?

I am tinkering about with CAD and thought drawing the LE would be a pretty good exercise and help me understand the plane a bit better. I got to the horizontal and ran into an issue. When I draw the tail using the dimensions from the drawing, it does NOT look right. Like really wonky.

Regards weight of warp drive prop versus wood props on the Verner3V. I have one of each on my 2 Legal Eagles. Very little difference in weight.  Measured in a few ounces and the warp drive ground adjustable makes fine tuning easy. Only downside of warp drive is if you have to hand prop. Not good

Let me make that decision for you.If you don't use them, with vibration the bushings will fret the aluminum crankcase which will lessen the torque on the bolts  which will fret the case some more and waller out (technical term)    the bolt holes, etc. The same will happen to the firewall to a much lesser degree. I'd make the washers out of 4130 to boot.

1/2 vw / Re: 26mm vs 28mm Mikuni carb

I just wanted to respond to this old thread. I converted to the 26’s and ended up with 150 jets. I discovered my issues were vibration related. The biggest solution I found was to torque my motor mounts to 6 ft lbs before every flight. After I did this  the motor never acted up again. That and the carb braces. They go rich with vibration and sound like they are cutting out. 
I also detected a rough spot at 2800 rpm that I avoid. I found this by watching my go pro camera shake in its mount on the jury strut. Goes smooth at 2900 and 2700… sounds crazy, but true!!
Hope this helps

Hey Leonard. I'm Bob. I luckily found your post on this forum by searching Google. I'm wanting to change to the Mikuni carbs on my 37 HP 1/2 VW. Summit sells two VM26 carbs. The VM26-606 has a button you pull for the choke, and the VM26-8074 has a lever. Which one did you use, and have you made any changes to the jetting etc. since.

Kinda like a 3D puzzle but one you have to also make up the pieces as you solve it.

I finally relented and replaced the 1/2 bolt-bushing with 5/8" as it made more sense for welding the 5/8" tubing.  Also the engine side will get 3/8" bolts as that is what the shock-mounts are designed for.  Now I wish I had gone with 5/8"x3/8"(bolts) all around.  To late on the airframe as the bolt-bushings are only 1/2" and I'm not about to grind them out to reinstall.  Well not yet anyway.  Anyone else dislike doing a job twice?

The jury has yet decided if the washers are going to get welded or will remain part of the jig.
