Power-to-weight calculator ?
Enter the flying weight and the full-throttle power - or the current and cells - to see the power-to-weight ratio and the kind of flying it suits.

How it works
Power-to-weight is the full-throttle power divided by the flying weight. With current and cells, power = amps × cells × 3.7 V.
Rough guide in watts per pound: under 50 gliders and gentle scale, 50-70 trainers and scale, 70-100 sport and aerobatic, 100-150 3D and pattern, over 150 unlimited 3D and EDF jets. One W/lb is about 2.2 W/kg.
It's a guide, not a rule - prop choice and drag matter too, so a model can fly well a little outside its band.
