I have a new Bme 102 in a H9 extra that I cant get to run right.
The first flight was with a pro zinger 26x10 turning 5700 it ran fine on the ground but seemed to run lean in flight,,, it ran very erratic, On my second flight it ran the same way.. When I did a snap roll the plane suddenly lost all power,, and I couldnt advance the throttle to more than idle.. it went in...I snapped the carbon fiber gear and broke a prop,,

After I replaced the gear with the stock aluminum gear, I flew the plane again today with a Menz 26x10 and adjusted the motor as per BME's instructions, they claim I should get around 6400 turning the menz prop. I could only get 5800.. I flew the plane and It did not run erratic like the first two flights but on my second flight of the day I attempted another snap roll and the same S**t happend the motor lost all power..I thought I was deadstick but as I got the plane closer I heard the motor still running. after about ten seconds I was able to throttle up again to come around for an approach as I was coming around the motor lost power again,, I barely made the runway,, I came down level but hard and snapped the aluminum gear and broke another prop...
Two sets of gear and two $40 props later........
Does anyone have any good advice, Thanks
