The following setup is shown as a worst-case scenario indicative of some
aerobatic pilots’ setups. It is not recommended to use this setup without proper
voltage regulation for your servos.
Airplane 40% YAK
Servos 9-JR8711’s 1-8317 (throttle)
Batteries Two 4000mAh 2-cell 7.4-volt Li-Pos
Regulator None
Engine DA150
Weight 40 lb
Flight envelope Aggressive 3D
Average current 2.62 amps
Peak current 17.8 amps
Milliamps (used per 10-minute flight) 435mAh
JR8711’s and 8317’s are rated at a maximum of 6-volt 5-cell use. Using higher
voltages will void the warranty.

In the example above, the average current was 2.62 amps, which calculates to
435mAh per 10 minutes (typical flight length). It’s recommended that only 60%
of the available capacity be used to ensure plenty of reserve battery capacity. In
this example, using two 4000mAh batteries (8000mAh total capacity) x 60%=
4800mAh (available usable capacity) divided by the capacity used per 10-minute
flight. 435mAh would allow up to 11 flights of 10 minutes each.
