My Ailerons are at 50% throw so its not twitchy and flick dual rates for a sweet roll. The plane will not knife edge without a lot of aileron mixing so dint get to try that
Out of curiosity what servos did you use for the ailerons?

Also a major mod I had to do was to have to reduce the length of the cabane struts by about 10mm ... yes i had to cut them and drill them again as the present length if put just wouldnt fit. I am surprised as i did not hear anyone else needing to do this mod.
I ran into this, but I found that all I had to do was move the struts out to about 1/8" of the edge the hardwood support in the fuselage.

This with a tiny bit of bending, of the carbanes, fixed the height difference.

In other words I made the struts slightly "wider" and thereby lower to account for the difference.


I haven't maidened my plane yet.

Mine is powered by a T.H. .46 2 stroker using a Bison Pitts Muffler.

With an 11x6 this engine HAULS on my Ultimate 40S, so I was considering putting on a 13x4 prop on this plane to slow it down a bit.

I also ended up NOT inserting a spacer for the wing struts.

Rather I installed them as is, then I used thin CA on the base of the strut supports to harden them in their new canted position.

This worked rather well.
