Okay, looks like we're leaning towards a 6:1 internally geared brushless motor (https://www.aliexpress.com/store/produc ... 80679.html
to give us our 500 RPM propeller speed.
Comes with a controller.
With a 13s, 2p lipo for the 25 minute endurance heat.
A digital volt/amp meter will allow the pilot to maintain a >30V throttle setting via a HALL twist grip on the end of one of the steering sticks.
What charger could we put between the battery and the panels?
Does all this sound reasonable?
