Estimated performance

Of course, the performance depends a lot on the engine and propeller. The powers of engines from different manufacturers are not completely comparable. These values are constructed according to the manufacturer's announcements and instructions for use. So the end result may not be what is described here. But gives direction.

Level speed

The horizontal flight speed is based on the assumption that the propeller can operate at full power, so that the maximum speed is equal to the fully open throttle and the revolutions at the maximum revolutions of the manufacturer's continuous power.
