I am also building the 330. It will be assembled with a 3W75 rear carburetor. My first impression "out of the box" was that this plane was too large for a 50cc. It seems no matter which way you cut it the plane will weigh 17lbs. This is at the very top end for any 50cc engine in my opinion. So we will see how I do with the 75.

Anything in front of the wing tube will be fair game.....let the challenge begin.
