Joel,
I'm getting the 1050 from a guy in CA, I'm not sure though if he has more batt packs. I'll try to ask him for you.
I fitted and APC 8x6 prop, yeah, I had to use the adaptor that came with it. Hopefully it won't burn out the motor though
Let you know after I test this weekend.
Btw, what's the range on your cub (altitude and distances-wise?)
Shaun
