RE: Brushless or Lipo - one or the other
Mrstingray,
I’d go with the brushless set up and your current batts. For $145.00 shipped you can have a mega 16-15-6 + a castle creations 25amp ESC + prop adapter. The efficiency of the brushless motor will give you the best of both worlds i.e. more power and greater flight time. You will not be disappointed. 3s LiPos can then be added later without worry of burning up your motor.
