Servo Centering/LRP AI Runner

[USATorque55]

I've been having some annoying problems. Every once and awhile I'll have my servo center incorrectly. This servo has been ran in water before, but I don't think its ever interferred with the steering or had any other problems. The servo is a Hitec HS645MG, with a Perfex 2ch 27mhz RX, and an LRP AI Runner.

it always goes to the same side, so all I have to do is unscrew the screw, pop off the servo saver, turn on my radio, slide it back on. The saver is in great shape. Nothing appears to be stripped.

This only started happening after I used my AI speed control. Has this happened to anyone before?

About the LRP AI Runner:

Can I run this on 7 Cells, the ESC thread claims 7 is okay. Tower claims its okay. I'm running a Lathe motor in a 2.2 Crawler TLT.
So is 7 cells okay?

Another question, Any way to stop the backwards recognition of throttle? I always have to just turn it on, and reverse the TX throttle. Glad this isn't a mod motor with timing. Any diode I can install to fix this?


These are such minor problems but I want to see if I can fix em.

Thanks for the help,
