DSM (Digital Spektrum Modulation) seems to be some fancy name Spektrum have given to the frequency used by their controllers.


This is the power capacitor which people are talking about. http://www.spektrumrc.com/Products/D...ProdID=SPM1600

It plugs into a spare socket on the receiver and maintains power over the receiver.

I think the theory is that acceleration can cause glitching because new speedies can draw so much power that the the voltage drops over the receiver and robs the receiver of the power required to turn the servos.
