So I have a 10 cag, and mostly use Hitec digitals, Been experiencing subtrims and end point moving off previously set positions on a couple planes at least 3 now to date, I notice this when using multiple servos per channel, like dual elevator servos, I get to the field and one is off where they were matched via the TX mixing before.

Today I was working on my P-47 which i have a 5645 programmed to 10% speed and endpoint set via the programmer, it works my tail wheel retract. Runs off TX chn 5 which is still set 100/100%,, While working on the plane I notice the endpoints are now off on that one too, so much to the point it broke the servo tray loose.

Could I have done something or should I send the TX in??
