Default Servo or Radio Settings

I am running an M11 and Hitec 7955 servos.

I have a slight problem that I never noticed until a fellow racer pointed it out to me this past weekend.

I always turn my buggy off first and then the radio. Well it just so happend that while I was getting help replacing a part we noticed that when I turn the radio off first the servo goes into full throttle. It does this automatically.

It dawned on me that if I ever lose radio signal I could have a big problem on my hands. It only does this if I turn the radio off first but not the other way around.

We re programmed the radio to sync the reciever again and can not figure out why this is happening.

Any thouhts.

When you bind the receiver to the radio, do you hold the trigger to the brake position?

what Jesse said!! your failsafe is set to full throttle instead of full brake..easy fix, just rebind at full brake

Still wont set right. Maybe I should pull out the instruction book and try it again.

Before resetting fail safe check if you have your servo reversed in your settings also.

I would suggest rebonding at neutral or slight brake not full brake. If the failsafe engeges and it's set at full brake the car will come to a screeching hault and prob get smashed by other cars on th track. At slight bake or nutral it will coast to a stop and or off the track. The othe. Prob with full brake is when the car is on and the radio off the servo will sit there and strain to hold full brake, not the best position fir the servo to stay in for awhile. Just a thought.

+1 I had my father pitting for me during a race and he forgot to shut off my receiver after my race. My failsafe was set to full brake. Ended up frying my brand new 7965. I've set failsafe to neutral since then.
