Snap,
On the batteries... If you put all four (two batteries in paralell) you still will be short on amperage for that amout of servos. My plane took 21 amps to fly pattern.(6 8611s and 8 8711s) The two fromcos only delivered 16 amps. When I had fromcos in it I had aileron servos stalling. I switched to two thunderpower 5000 mill. amp packs( I believe they where capable of discharging at 60 amps each)each and saw a tremendous difference in the servo power.
Plane looks great! I can't wait to see you at the Nall.
