In my case, the only rotor that is strong enough for my MonstIR and small enough to fit in my HDX5106 is a prop pitch. Since the HDX5106 is a crank up, the rotor has to fit ENTIRELY inside the tower

Gene, the current draw at startup is a bunch higher than the running current. Sorry, don't know how much higher. You are probably ok with the 3 #12 wires but you might want to test it on the ground b

Handy to remember.. AWG 10 wire is about 0.1" in diameter and 1 ohm/1000 ft. For every 3 gauges, the resistance doubles. For every 10 gauges, the resistance is x10. So.. 200 ft of AWG 10 (up and back

It's worth noting that these "modified" pp gearboxes are no longer capable of doing the antenna rotation tasks usually asked of prop pitches. They trade off torque and braking capability (holding in

Thanks for the comments on PPM's. They pretty much fall in line with what I have observed over the past few decades of using them. Probably about 35 VDC with a 200 foot loop of # 12 should give 1/2 t
