Hawker Sea Fury – 5-blade Electric Conversion

5-blades of Sea Fury Heaven…but it Takes the Right Motor

The power system for the Sea Fury is as follows:

  • Motor: NeuMotors 1515/2Y with 6.7:1 gearbox
  • ESC: Castle Creations Phoenix 110 HV
  • Battery: NeuEnergy 10s 5,000 mah Lithium Polymer
  • Prop: Zinger 16×14 prop (aluminum hub with wood replaceable blades)

In sizing an electric power system (we’re talking propeller airplanes here as opposed to EDFs), the first question to ask is “what do I want my power system to do for the airplane?”  What I mean is, Continue reading
