RE: Hostetler 33% Decathlon
Ron, what do you not like about the "wood sliders"? I've studied Wendell's plans thoroughly in this area and it looks like a good way to do it. It even sets the 2 degree dihedral. It makes the interior also look more scale which it wouldn't with a wing tube. I have an 11 year old PT-19 which Hostetler designed with the same box/plug arrangement and it has never given me any trouble.
