Ran across a thread on another forum discussing servo dynamo effect, and the OP in that thread seems to think that a quick movement of an control surface created a reverse voltage spike...hence taking out his ECU. I see Emcotec makes a device to combat this phenomenon in the form of the DPSI OCP http://shop.rc-electronic.com/downlo...yer_OCP_EN.pdf

Curious about this, so I had a go at a little testing using an Hitec 5955 servo. Quick/rapid movements of the servo arm produced voltage readings approaching 1.9v or 1.18 amps . Wondering if this backfeed would take out an ECU or receiver.
