Mark,

This past weekend I did get to see the 46gt in person. It was mounted in a lanier edge (73" span?) and it performed very nicely. I was not fully broke in yet, but had no problem swinging a xoar 21x8. The engine looks very well built. This one was hard mounted on beams and had the simple box muffler (loud). The owner did not know the RTF weight of the setup, but it was likely between 13-14 lbs. The airplane flew very well at this weight (1000+ sq. in. wing) and perhaps it's the only little lanier edge I've ever seen without 2 lbs. of lead in the nose to get it to balance.

The rear exhaust version although smaller, sounds very appealing for sake of keeping pipe setup simpler and cleaner....as well as lighter. However, I think your estimation of required rpm and prop are right on...and the 36 looks like a real longshot.

Your kit will be a few ounces lighter than my prototype due to changes in former web thickness, lightening hole sizing, etc. Small changes to the lite ply parts yield a nice little weight change in the end kit. I will be excited to see how your project turns out.


Regards,
Mark
