My scratch built messersmith ME 163 maiden flight.
The prop is too soft and went into flutter and the sound from the prop was louder than a nitro engine.
The motor was a Turnigy 28-26 1900 with a 25 A ESC and a 8x4 prop.
3 cell 1050 Mha Rhino batt.
Weight is 600 gram (21 ounce).
78 cm span. 51 cm long.
And a new 7x7 speed prop
But now I use a Turnigy 28 36 3700 and 4,5x4,5 prop and 1800 mha 40 c , 3 cell batt.
