Hi All,

I went out flying this afternoon, what a beautiful day. Had several successful flights. But I was having some issues with my engine. It is a Thunder Tiger 46 Pro. What happened, I had a bumpy landing and after it got on the ground I tried to throttle up to taxi back. I bumped the throttle but nothing happened, I could tell the engine was still running. Tried it again - no go. So I slowly moved the throttle and then it throttled up. I took the plane back to the pits and after a couple throttle ups, the problem seemed to clear up so I went for another flight. While the plane was in the air I could hear the engine surging. I decided to land and try to figure it out. I tried to start it back up and now it was having trouble starting up, so I played with high speed and finally got it to start. Took it for another flight and it still surged. Gave up for the day and decided to see what you guys think is wrong. Up until this point the engine was running perfect.

Some people at the field think it could be the glow plug, others think it is the low speed. Any suggestions would help.

Thanks.

Ryan
