I put a bigger engine, Moki ( RCS ) 150, and squeezed the engine for max speed with a 23.9x38 prop. To the tune of 160+ mph, yes one hundred and sixty miles per hour. Increased the weight of the airframe to handle the speed and power. Of course you can always throttle the engine back to a third and get a 40-50 minute flight time.

Please trim to taste
