I need help in acquiring the current consumption of the following servos and receiver, I've tried searching the net but no luck... maybe someone here have an idea or found it somewhere in the net.

JR DS8911 Servo
JR DS8715 Servo
KO Propo KR407S Receiver

I want to calculate on how long will my receiver battery last.

Best way is to measure it yourself - start with peaked rcvr batt and run for a measured time, say 20min. Then stop and recharge batt - what goes in as far as mah will be what your servos and rcvr really used during that 20min. Divide that mah by 20 and you'll have a decent rcvr batt power drain on a per minute basis.

The current consumption will change based on the load on the servo. The best is to do what the prevous person stated.


Pass you soon...
