Hi all, new to the hobby. Have had an Alpha for about a month now and I still can not get it right. The engine was not set correctly at the factory, and none of the guys at the club have been able to help me out. I will throw out my problem and maybe someone can help. The engine starts great, usually with one flip of the prop, however it will not trasition from idle to full power without bogging out. One it sputters and then peaks out, everything sounds good. It's only in transition that I have problems. I have spent hours making 1/8 turns on my low end needle valve, and have had to land more dead stick than not. Has anyone else had this problem with this motor, or did I get a dud? Any suggestions would be a appreciated. Thanks

P.S. When it does fly smooth it's a great flyer. Considering new engine.
