to Davesplace80 I have built the nobler with mechanical retracts and yes the push rods do rub because there is not to much clearence also they say to put a ply floor where you mount the servo use the thinest ply you can get. The quicklink screw on the throttle servo will stick up just past the wing saddle, I notched out the top of the wing for that, you dont see it and it causes no structural problem. I will suggest you use the Hitec 555 micro receiver in place where they want, standard receivers are to big after you rap them with foam. As for the wing tips I used gussets at all 90% angles both on the tip and in the last two rib bays.I believe in strenght.
I am using the L A 46 with a remote glow head on the side cheek.
