Hi DW,
I'm not familiar with the numbers on the Mega motors, but it sounds like we end up in about the same place.

I'm somewhat illiterate about how to post pictures; also I haven't taken any of the Magic yet. I don't know if it's me or a curse, but if I photograph a plane before I fly it I almost always crash! )-:

As for the wing. I drilled a pilot hole in the thick former in the fuse at the wing's leading edge. I used a short pointed dowel to mark the wing. I then drilled a pilot hole back through the wing joiner. I had grooved the root ribs before joining them and tried to keep the epoxy out of the grooves. I used a 3/16 dowel which I expoxied in with slow cure. I hardened the hole in the fuse former with thin CA. At the trailing edge I epoxied in a piece of 1/4 inch a/c ply and added some balsa triangle stock for re-inforcement. I used 10/32 bolts and drilled through the reinforcing plate on top of the wing. Simple, really, and easy to do even if you've already gone the rubber band route.

I plan to use the plastic spoon trick for my exit air. I really only have two flights on this great bird so I haven't had time to figure out the best throttle use.

What does yours weigh with the 30o0s in it?
