Radio trouble

[JensR]

The skysport 4 is a four-channel radio - enough for your truck and transmission, but this means that channels 5 and 6 on your receiver will be empty.

I found a German manual, at least it shows you a bit and you can translate parts with google:

Next to the sticks, there should be numbers, these correspond to the channel numbers on the receiver.

Next question is whether your receiver is BEC enabled and whether your ESC has BEC. Battery Elimination Circuit means that the ESC can power the receiver and servos - in that case, do not use a battery pack as one of the electronic parts might get fried.

Into which of the first four channels on the receiver you plug your servos/ESC does not matter to the servos/ESC, but they will then be related to different stick movements.
