I put about 100 flights on one with a 210 last summer. Do you have a cline reg. on it? I ran my 210 on the ground without the cline and it ran fine but when I flew it couldn't draw fuel aginst the g forces and dead sticked on first flight. Put a cline reg on it and haven't had another dead stick. Moki runs great. best engine I have. runing a 20x8 bambula on it. Keep it slow. The big control surfaces are desined for 3D and the ailerons will flutter if you fly it fast.
Flys very light. Great 3D plane. I really like my DP. If you want to take 5 oz off the weight put CF landing gear on it. My DP is 14.5#
