Which 40cc and what will it turn at what RPM.

Wonder what the numbers are for a 50 cc on a CF tuned pipe. I like the tuned pipe idea for this bird. If there is enough room on the bottom like the battery bay on the .46 it'll be the perfect place for one.

Hopefully the wheels are in the right place. Nosing over on a big wood prop can get pretty costly. If the gear looks like it'll cause the same nose over issues of the little brother, I'll put the Graphtech #215 gear on it, cut down the middle. I happened to have one from a mis-order. Turns out to be the right width and height. If not turning around the gear should do the trick.
