RE: rigth engine?
So far I have seen that plane flown with a DA 50 and a Zinoah G-62 and the power was just fine unless you are a pure 3_D pilot. Three weeks ago one of the guys came out with one of there giant YAKs and was using the DLE 55, I really liked that combo. As light as there ARFs are built it doesn't take a lot to fly them. Just depends on what the pilot is looking to do with them.
