I decided to give my excavator a paint job . I've now completely taken it apart and am preparing everything for the primer.

I'm still waiting for the missing pieces for the motor / pump. The pump came with a speedcontroller for the motor. I still have to check if has BEC in it or not. I also purchased the optional module that allows the motor to run with 2 speeds so that the pump does not always have to run at full speed.

I'm controlling the excavator with a Spektrum DX6i and 2 receivers (Dig and Drive)

The Drive receiver will control the 2 motors that drive the tracks, the swing and the lighting.

The Dig receiver will hold the 3 dig movements (boom, arm, bucket) and the pump. according to the instructions I will need a multiswitch in order to allow to control the 2 speeds for the pump.

If I understand well, the optional 2 speed module can not be connected to the receiver. It needs to be controlled by the multiswitch.
