I'm having problems with my new Nexstar and the OS .46 - my first R/C airplane.
I was able to get it off the ground this weekend at 1/2 throttle and flew/landed it successfully, however it hesitates/sounds like its choking, is very sluggish and will only run at half throttle or below. I've done all the adjusting and tuning possible with no effect. Afterwards, a very thick, orange (slightly darker than the nitro I'm using) goop can out of the muffler. I beginning to think the nitro may be the problem, but the manual calls for between 5-20% nitro so I went with 10%. I'm new to the hobby, so any help you guys can offer is greatly appreciated!
