Hello Kim!

I was able to get fly three flights today. First start, started, went through calibration at 60k+ rpm, went down to idle limit. Went to full throttle for 10+ seconds for max rpm and it made rpms. Went to idle and started to taxi out. Delayed or sluggish throttle response. It would take 6+ seconds to accelerate to full throttle, making rpm. I did fly it with no issues, but kept throttle response in mind. Before the next flight, I started to search for throttle settings in the radio. I fly Jeti. I found that when I was probably trouble shooting earlier in my engine issues, I had increased my throttle stick movement to 100%. This isn’t travel adjustments or End Points. I set the Throttle Stick movement back down to 50% at both ends. Relearned R/C Engine settings. Perfect start, the engine went through it’s normal calibration. I did another 10+ seconds full throttle calibration. It met rpm numbers. Acceleration was back to a normal running engine. Had a great flight! Fueled up for the next flight. Went to start, and it had a failed start not reaching calibration at about 58k rpm. Let it cool down, next start it went through normal start, normal acceleration and a good flight.

So, the issues are definitely communication. Check all of your transmitter settings that are rarely looked at after set up. Good luck! Dan
