I smoked one DelTang receiver through carelessness.  
The motor driver devices burned out, but the P outputs still work, so I used the receiver for a model without a motor.

I would add a diode but many of my models are powered by 2xAA, so I still need a step-up (3,3 V) to power the receiver.
Not much voltage available to throw away.   :(  

Same with the Pololu DRV8835/8 motor driver.
I use the VM input to conserve voltage, but it has no reverse protection that way.

Monorail modelers have a one track mind.
