Hi all
The power cap on the reciver helps with HIGH Amp Draws from servo (as when you nail it with a good servo the BEC in the spedo cannot cope with all the amps and there for the volts drop and your reciver goes into failsafe , what a cap dose is it stores a little bit of power for when your voltage drops , and when it dose it compensates until your esc gives the full power back , dont know if explained it clearly enough its hard to explain
, try a powercap , wheres your arial i know carbon fiber can sometimes interfear , even with 2.4 i put my arial up a straw or i get interferance.
