When you recalibrate the revmax did you make sure you had a linear throttle curve?

yes 0 , 25 ,50,75 , 100 I think that is a problem form revmax because I don´t think that the servo could cause that problem

have you checked the tuning on your engine? If you are too lean, the engine will lose power as it heats up.

Another thing, check the throttle arm on the carb, make sure it is not slipping!

The RevMax is solid state electronics, they dont just "go bad".

I hope that it hasn´t gone bad , the carburation is ok the one thing I havent check is the carb arm as you said it may be slipping .
