I see you haven't built the wing yet - good! I wouldn't be a hard thing to do, you just have to make sure you place the gear so the wheels are a bit forward of the C.G.

The Dash 5 is a GREAT flying airplane, one I would love to have, just dropped all my $$$'s into a 33% Extra, though...I had a kit, and when I got out of the hobby, let it go, regret it since!

It may even be possible to reinforce the fuse right in front of the wing, and place fixed gear there. I don't remember the exact configuration of the Dash...

Yoshioka made some great kits! Had a Chaser, that started with a .29 Supertigre, stock exhaust, ended up with a .34, on tuned pipe, just before going for a swim in the Wabash River (yup, both me AND the plane!!)
