So small yet so important. Why? Well let me explain it like this.

You have an electric heli with the proper matched ESC (Electronic Speed Controller) for your motor and the ESC has a BEC that powers your receiver from the same flight pack (battery).

Say you were to give cyclic quickly (open the throttle) there would be an inrush of current towards the engine to get the REVs up. This in turn would cause the voltage to drop dramatically on your receiver. To put it another way, for a short moment in time it is possible that your receiver will not have any power. If this happens we get a situation called a brownout. Typically any receiver (ESPECIALLY the 2.4G receivers) takes time to boot up after a brown-out. Time you normally don't have when flying inverted close to the ground.

This is where this little device comes in. What this does is it stores an electrical charge that will power your receiver for up to 100ms, which is normally enough to power your receiver untill your BEC can correct the for the power dip. And yes, it does work well.

Plug it into a pare channel or use a Y-lead if a spare channel is not available.
