My 500 only goes to 148K at max throttle. Idle is about 50K. I have looked at the pulse width and they match the book numbers for the 500. Where should I look for a problem/solution, bearings or fuel pump. Motor ran fine until yesterday. The history shows various spooldowns from 19-24 seconds with no trend showing.

Tom,
It seems you have a restriction somewhere. You can try bypassing your fuel filter by using a 4mm Festo for 1 test and see if you reach max RPM. You also want to look at your battery voltage and make sure it's fully peaked.

Let me know how this works out and we'll take it from there.

Carlos,
Went back and reset all parameters and guess what - 150k. Guess a "Bob Price"electron got loose and had to be reoriented.
Good luck with your new business, we need you!
