I have a tekin esc with 208 installed.I am running 2wd offroad and every so often the speedo will lock up.It will make a squeeling noise when you apply gas.Turn it off and back on it works good.Happens probably 3 times a race day.Can someone tell me what might be causing this. thanks

That squeeling noise is probably coming from the motor. The RS doesn't make any sounds, the chimes come from the motor.

Check your rotor bearings.
