Hey Dan,

Awesome choice for an E-plane if I do say so myself.


As to why RPM is important its the difference between work-in versus work-out. RPM is is part of the measurement of the actual work done by the motor. Lots of folks (like me above) focus on how much energy is coming out of the battery, but that doesn't tell you how much work the motor is actually doing. If one battery and esc combo make a motor turn 8000 RPM with a 20x13 prop and use 60 amps and 38 volts, but another battery and esc turn the motor + prop 8000 RPM at 57 amps and 38 volts then the second setup is 5% more efficient which means 5% more practice time for you the pilot.

That's my super quick "down low" on RPM, but I'm sure you can learn volumes more from the pro's on RCG.

P.S. Your altitude makes a big difference in prop performance, but the 30-10 is so over powered you should have no trouble eaking out a few extra RPM to overcome the loss of thrust. Most folks I know are restricting their 30-10 at sea level fields to 85% or less of max power so a slightly higher output for your throttle curve should give you similar results. Of course that won't do anything for the higher true airspeed you'll need to fly for the same "look" in the air.
