STEVE AND JOSH on sabertooth or other h-bridge all have protection,but not the motor motors will still burn up,some have a connection to turn off the motor (brake) ,but sometimes the brake is use to stop the motor from a protection circuit that you add

HI Robotmaker.

Im with you now , i thought you ment the controler would burn up.

I kinda thought that the overload protection would work fast enough to save the motors under a stall condition.

oh well i guess i need some 24 volt current limiters .

Ok I have current sensors coming for the motors just in case Jarvis gets stuck.on something. Also IR sensors with.better range.

Also I have 10 sets of xt60 Turnigy connectors , which are rated at 60 continuous amps.

Ok I have been trimming the port for a better view. It needs to be able to scan left and right far enough to see 8 inches in front of each corner. I believe I will trim a bit in each direction.
