DaveFlynn,

Thanks for the info. I think that a 60 E-Flite would be too big. I have to stay in the 10-11" prop range in order to keep the prop hitting the ground. The airplane will not be more than 6 lbs. This is a Canard type A/C and so 3D is not in its future.

I think that maybe I just need to try something. I just would like to know how the prop diameter changes will effect the ESC and/or battery I choose?

Thanks
