Hello timo

I have also ordered and installed the product. I am very satisfied. No 1 receiver and of course the transmitter. But you could connect up to three with the transmitter. For example, if you have 3 cars but only want one control unit.

Hi, I would just like to say that the Absima CR3P can store 10 models, so you can bind up to 10 receivers.
3 channel means that you can connect up to 3 servos or 1 controller and 2 servos to one receiver.
