RE: Stryker Brushless Motor
It would depend on what kv inrunner you have. One like the 4200 kv unit would take a tiny prop, 5x5 on 3s lipo would pull around 16.5 amps and only develop around 8 oz of thrust.
That high of a kv unit would be better off used in a gearbox set up. Same motor/pack on a 3:1 gearbox, spinning a 9x8 prop would give you about stock performance and amp draw.
