No John after I put it back in the plane, it still was playing up again soon as put back in plane, had it running great on the test bench good throttle response good rpm no good response all round. I was told that cause the motor is inverted I could be flooding the glow, os 4 stoke glow plug in and seems that it has done the job. I also had probs with the plane leaning out after ten minutes in the flight found out it was the tank vibrating causing the fuel to bubble causing are bubbles in fuel put some foam around the tank .
