RE: Great Planes Combat Spitfire GP/EP ARF
My Great Planes Combat Spitfire was Ready-To-Fly at 39oz (or 2.4lbs) with the 10oz 3-cell ElectriFly 3200mAh (20C) LiPo pack.
The current draw was only 32 amps for 370 watts. That's a powerful 152w/lb and the power system can handle full throttle for the entire flight!
