I have a AR6210 reciever in my bot and the drive motors will not failsafe, but the weapon motor does so fine. Ive heard people saying that it might be the esc we are running a scorpion xl in the bot. Is it the reciever, esc or some other underlying problem.

From product page on RMP-

SmartSafe failsafe system (Not proper failsafe for combat robotics)

You'll need one that failsafes to preset positions or outputs null signal when connection is lost. I prefer the preset positions as the null signal doesn't work with some motor controllers. the hobbyking R610 and R410 both failsafe properly and are nice and cheap. I'm using them in both of my 30's and my weaponed ant.

The AR 6255 is the only 6 channel DSM2 receiver that I know of that failsafes to presets on all channels. RMP has it for $80.

IF I recall correctly, even using the 6255 you have to power up the receiver with the bind plug, REMOVE THE BIND PLUG, then initiate the bind process with your transmitter SET ON THE FAILSAFE STICK AND SWITCH POSITIONS.

If you do any part of that incorrectly, you will not get true failsafe (i.e. 'null' signal instead of preset when signal is lost.)

There are some ESCs that will go to 'no output' when the signal goes to null, but many will either continue to output 'last good signal' or get all glitchy. I do not know which ones do which, because I have always bought the full failsafe receivers.
