RE: Electric motor for SPAD SPADET-40
And with 6 Sanyo 2400 Nicd SubC cells, 9x6 prop, 3.5 gearbox:
Weight (oz) = 54.2
Batt Amps = 25.5 Motor Amps = 25.5 Motor Volts = 6.6
Input (W) = 168.5 InPLd (W/lb) = 49.7 Loss (W) = 43.0 MGbOut (W) = 125.5 OutPLd (W/lb) = 37.0
MotGb Ef(%) = 74.5 Shaft Ef(%) = 68.5
Motor RPM = 30022 Prop RPM = 8578
Thrust (oz) = 23.4 PSpd (mph) = 48.7 RofC (fpm) = 409
Time (m:s) = 5:53 and to level flight and throtle 80%: 10 min
