Only happens when I "Chop" ( I like that term) the throttle to minimum when trying to slow from high speed motion. I can not replicate the prob no mater how hard I slap the luge and throttle around sitting still with the turbine running. All of your ideas are valid, but I need to see if the ECU count for each position of trim/ throttle is even in the ballpark since i have nothing to compare to. My question was sort of a survey of notes to see what several other pilots get on their varied setups for the learn RC Parameters. I would like to make mine somewhere in the average of the info I get and then try it again. I have thought of "padding the trim" if need be but would rather not. I will be in touch with Mr Matt also, he has been great help with everything.

Although not a genious, I am also a, so called "WIZ" in the electronics design and real life production of both RF and digital circuits and systems for the Naval Research Lab in DC. I am not saying that as a bragging statement, believe me, I am just letting people know incase you also need help in troubleshooting. I am green and wet behind the ears when it comes to the R/C world's specific components, but have extensive experience in solving RFI / EMI problems on the ground and in space, for example. I would like to give as much as I have taken from this forum.

thanks
