Yea I think im going to lean towards the DL-30. Although id really like to have that 2.4 Brison though. My DL-50 that I had was a awesome engine, im sure the lil 30 is going to be just fine. I was thinking of that CRRC 40 because it is more cc's, I like more. If I could I would put a DA-150 on that plane, lol. Just kidding. Yea I might just have to go with the 30.
