No, ours is the same as Seba's. Each prop can run at a different speed. What's common between the props is the torque multiplied by the rpm of the prop, which is a proxy for power. Each prop absorbs the same amount of power, so if one prop is wider than the other prop (for instance...) the torque into the prop will be increased, and the rpm will be decreased. Also, we don't have any belts. We use gears.
Ok, so you can restrain one prop, then turn the motor and the other prop alone will move. This would be at twice the RPM than if both were moving ??.
I was not suggesting you used belts, it was another contra unit in Austria.
Can this unit be re-engineered to run on an outrunner or direct drive innrunner (210/230 kv)
This would increase the market size.
