Bruder Excavator Conversion Radio Setup Help Needed

[Papy]

I added 2 sticks to a futaba f14 and this works great.

The two main sticks are used for digging, the two additionnal allow me to operate the tracks + auxilliary function (rotating a grapple, for example). As the f14 is an 8 channel radio, this leaves a channel for a switch device in order to activate the pump/lights/etc...

The main advantage is that you can operate tracks and equipment simultaneously.
