Well I was excited about my DA-50r that I got updated a couple days ago....but here's the problem.

The engine is already broken in so I spent about 8 hours trying to put my Ultimate Biplane together and finally the DA50r....it flew perfect...the next day when I went to half throttle the engine would die like it was losing power....I was like ***....

So I called my friend had a few DA engines and he said make sure to check the needles...so I checked and they were factory settings needles. 1 7/8's on high end and 1 5/8 on low end...the thing that bothers me is that is ran fine..

I was using 93 Octane Gas from Shell Ethanol Free mixed with Amsoil Saber Pro 100:1 Premix.

The second flight I almost lost the plane because the engine almost died on me on half throttle...I was lucky to land it because it seemed to have no problems at the low end...only when I go half or full throttle...half throttle the engine wants to die...at full throttle you might as well expect a dead stick....

Anybody else have this problem? I waited almost 3 weeks to get my engine back from being serviced and got it back and 2 days later I had to send it back again....geezus....
