If you go with the plexi, you may want to make it removable so you have access to the tube and fittings

1/2 vw / Re: Prop For 30 to 32 HP Engine

Thanks. I was thinking about a 52D x 18P for a 30 HP that we want to prioritize climb with.

This is going back a bunch of years.  I know your engine is a bit larger than ours was, but maybe this info is useful. 

I found some notes and the props we used with our 69mm stroke x 90.5mm piston dia  half-VW engine, tested to be 29hp using wood bar dyno. Mounted on a bit heavy LEU.

1st prop, Hegy, 54x22, max static was 3090rpm, was very sluggish on hi speed taxi tests, did not fly this one.

2nd prop, mfg unknown, 54x20, max static was 3160rpm, we flew this one.  It was barely adequate for me, the heaviest guy around 220 lbs.  It seemed to fly well with the lightest guy, about 150 lbs.

Some other notes I found from 2013 - don't know resulting performance of any of them:

- Sam Buchanan, 45 hp Casler, Tenn Prop, 58x24
- Scott Johnson, 78x92 engine, Tenn Prop, 54x24
- Alan ----, Mosler 78x92, ? mfg, 54x24
- Les Homan, Casler 94x86, Tenn prop, 58x24

What prop diameter and pitch are you guys & gals using for your 92mm x 69mm 1/2 VWs? Most of these are rated at 30 to 32 horsepower.

I had the same problem with printed plans: https://www.eaglersnest.com/forum/index.php?topic=1640.msg9317#msg9317

Curious why you scaled up, I'm getting ready to order 4130 tubing. TIA

Thank you Charles. I never consi8dered the fact that the tapes are saturated with glue. I read the stewart manual several times and the only time delay reference was to get the Ekofil on before 12 hours. Thanks for your unofficial opinions & histori8cal results with your legal eagle.  Possum

I do not present myself as any kind of authority on any build process.  The LE XL is the first airplane I have ever built. This is only my opinion.
Question 1:  I didn't use any waiting time. I was too anxious to let 12 hours pass. Just be sure every thing is dry and clean.  The EKO bond is great glue. (3M is the same stuff IMHO)
              2: I didn't shrink the doilies.  While using the model airplane iron they start taking
                  the shape of the inspection ring. The tapes are saturated with glue and don't shrink much because the glue is heat activated and sets-up while ironing.

Regarding your use of the 3M glue.  I have fellow ultralight flyers who have used it and are getting the same results.  I have watched them apply using the same process as Stewart System and it works the same. He has been flying his ultralight for at least four years and has had the same results as my Le XL.  I have absolutely no issues using the Stewart glue after 10 years.

To: Charles DeBoer,  Charles I'm using the 3M glue and not trying to meet the STC requirements. However I am using the Eko wash and Eko etch to prep my tail feathers for glueing and fabric attach. I have 2 questions: 1. Is there a time requirement for adding the glue after applying the etch? eg must apply glue before 12 hours after etching.

2.Should the tapes and insp ring doilies be pre shrunk to 250 degrees before glueing to fabric? Thanks for your help with this.  Possum
