L16Pilot,

Congrads on the test flight. Sorry about the mishaps on landing. Glad damage was minor. I added scale split flaps to mine also. With the flaps down it slows real quick with the power off (which I guess you know now). I usually carry just a little power all the way to the ground and land on the mains. It gets too slow for me to try to three point with flaps, unless the air is dead calm. Regarding engines, I have a McCoughal 25cc conversion, because that is what I had and I needed the weight forward anyway. It turns a Master Airscrew 16-8 three blade 7,900-8,000 rpm. Flys scale, not over powered. By comparison, I have a DLE 20 in an H-9 Hellcat. It turns the same 3 blade Master Airscrew 16-8 prop 8,450 rpm. Go to a bigger prop and slow down the engine. You really don't want it going much over 9,000 rpm in the air, or so I've heard. Here is mine. Over a hundred flights on her.
