Tony, my spool down time is slow. It takes around 7-8 sec to go from full to idle. I think my ECU values need to be changed. Right now it is set @ 23 on the deceleration delay. Also what kind of ECU battery are you using? Any problem going to Lithium Ion? And last what kind of thrust are you getting, I go to 125,500 on my ECU @ full power. I would like to talk to you if I could get your phone # that would be great. Or if you wouldn't mind giving me a call @ 954-816-7917 Thanks for the reply I cant get any response from TJT Mike
