I think to buy batterie for example this motor http://www.hobbyking.com/hobbyking/store/__25138__turnigy_trackstar_waterproof_1_10_brushless_power_system_4000kv_80a.html

In description i read “Battery: 2-3 cells Lipo (5-8 cells NI-xx)”

you recommended to buy for this motor 2s or 3s?

That’s the one I purchased. I run 3S on it. If the speed is a bit much, depending on your transmitter, you should be able to dial back the top end to reduce the speed (max servo throw). (This will not however reduce the torque / power dumping into the motor and drive train components on start [if you have issues with things braking].)

if you buy a 3s as I reduce the voltage to servos and receiver?
advantage disadvantages usr 2s or 3s

The esc has a built in voltage regulator, you don’t need anything else. 2s, 3s won’t change the voltage to the receiver and servos.

the dude is the battery 3s break the motor or electronics.

@D_Myers
I am a beginner and wanted to know if you recommend for this project use 3s select more fun than 2s. or better use 2s for begin?
