Agreed with what you said.
When choosing a power system, we need to consider what it needs at take off. IMO, the mentioned power system in post #4 would give John plenty of power, light weight, and very reasonable in price.
The Torque 4014 is a good motor, but the motor itself is close to $100.00
John is building a light weight fuse and hopefully we get the plane ready to flight for less than 5 lbs. At 120 w/lbs (600w), I bet it will take off in less than 30ft, and will be fun. Dont you agree?
Note: I used the exact same power system with APC 14x7 prop on a 3D plane (weighs 3.8 lbs). Take off in less than 3 ft.
