These are the future of small engines, very low part count, very light and a great power to weight ratio. With the right propeller and airplane configuration these engines are capable of alot, atleast for their size. These are the smallest functional piston engines on the site. Please read the instructions.


Start in the air, throttle up and increase VTOL based on your own preference (the higher you raise the VTOL the faster you can go).

Never raise it all the way to the top because that will be too much for the engine.
