Rich,
Anytime the servo is being called to go somewhere it doesn't have the power to move to or even hesitates even momentarily anywhere along the travel or even loaded to point where motor isn't able to run at full rpm. The motor is being fed juice to go but it can't go so it doesn't move and the locked rotor or stalled servo occurs. When this happens the amp draw goes through the roof and you have very close to a dead short at the motor wires. This heats everything up really fast and the load is more than the electronics were ever designed for and it smokes the servo. Often it is a part on the board callled the amplifier that releases the majic smoke but when they lock up any part including he motor is suseptible to being fried. If it doesn't move for a few seconds that is all it takes.
K makes sense. Thanks. So, for instance, if you don’t set your end points and you are cranking the servo full but the throttle setup doesn’t allow further movement.

Rich, The very basics of this are EPA (End Point Adjustment)

One never wants to allow the servo to continue to attempt to move IF a mechanical stop dictates the end of the travel.

Just use the EPA to adjust the end of the servos travel.

Yes exactly. We do not have the issue usually with the channel 1 steering servo as we are usually backing the throw way back (in order to drive it)from where they would be stopped mechanically unless like say a battery shifts somehow and the servo horn locks against it.

Usually it is the throttle or remote needle that needs the end points correct and the throttle you have to set the braking end point as well.

When they flip if you have your failsafe set it will go where ever you set it too. Just make for certain there is no strain during full backtrigger because that is how many get smoked.

The radios that will bind to more than one receiver per model number you have to be certain you have shut off the boat you were on before changing models. Wrong model number will tell other boat to go where it can't most often.

Lots of scenarios to fry a servo or everything as when servo fails often it is a dead short. This can get everything in the box.

that is a darn good little unit for sure... (was my work grunt radio before T-FHSS came on board)

7PX for me and the 324RX are my favorite!
