What is the voltage tolerance on APM usually speed controller BEC gives 5.5 volt which AMP dose not like and behave erratic.

There is a LM317 voltage regulator on the APM 1.0 for external power source. Does the APM 2.0 have something similar?
I'm surprised it is not more clearly spelled out in the manual, but it seems that 5v +/- a small amount (like 0.2v) is what is required for APM 1. I assume APM 2 is similar. This is based on searching through old posts.
I am using a separate UBEC that outputs 5v,which has never cause a problem. It is just a shame that a lot of ESC's output 5.5v, which causes APM to do strange things.Otherwise I could have a neater setup inside my plane.
I would avoid plugging your 5.5v BEC into the APM 2 rail. You can buy a UBEC for <$15 that will output the correct voltage and be safer.
