High pitch squeal from motors... FIX.

[Long Range RC]

Hello Guys, If you remember how I told you in an earlier post that the one Hornet I had the Tarot 2 gimbal on kept having a high pitch squeal followed by a uncontrollable turn? I think I figured it out. I noticed that the speed controllers I have had a setting for the timing of the motors. If you are running a motor with more than 6 poles it needed to be at 16 Hz but the default setting is at 8 Hz. I changed the settings and built a new hornet with a new frame and it flies great. I also noticed that once I switched the Hz that my gains dropped from 179 to 116.

Something to keep in mind on any new builds you might be putting together.

Thanks. So much to learn. If you bought ESC's that were pre flashed you would never even know.
