RE: e-flite mini edge 540
Chris,
I'd fly it after all the effort you put in it. Like Rob said you just might like it. If not, you can always sell it after you fly it.
Rob,
No matter what you go with, I'd recommend the 2100 mah Lipo for sure. My flight times are just too short with the 1320. Good luck on your desicion with the motor. Did you get to see the funtana fly? What did you think?
