How much does your motor and moosecan weight.

Because if its over 20oz. In my opinion your going to kill your wing loading.

My knife ARF with a YS63 weights 5lb 4oz. The knife ARF is a heavy ARF. My motor is 18.25oz of that weight. And it flys heavy. But vertical performance great.

I had a TT46 and moosecan on it, and it would pull out of a hover real good, not like a rocket but good. That setup weighed 5lb. 2.5oz.

But I have a Knife Kit that weight 4 1/2 pounds, with a TT46and moosecan and vertical it like a rocket.

I have heard that alot of people that fly the extra 330 profile have a 46 on it and love it. With plenty of power to spare. The typical 46 size engines with moosecan weight approx 16oz.
