This is an account of how i fitted two channel radio control installation in my Caradoc.

I have put a small servo (Ripmax SD 200) in the right hand side tank which operates the reversing lever, i think the standard RC installation disconnects the reversing arm and a servo moves the valve gear direct.

The second servo for the regulator is on the floor of the cab, with a fine brass wire linking it to an arm on the regulator spindle. I've used the smallest servo i could find for the regulator (Ripmax SD100). The brass regulator arm is made of some brass strip silver soldered to a brass collet.

The servo mounts are made up of brass sheet cut to size then bent to shape. Brass nuts were the soft soldered on, making it easier to screw the servos on to the mounts.

I've put one of Brian Jone's RC signal smoothers in the right hand side tank. The receiver and battery pack just fit in the undercab box. Routing the ariel was the main problem, the best place is to have it come up the side of the loco and into the cab. I will eventually diguise it as a hose pipe.

Still to add safety chains, lamp brackets, driver etc. May also replace the black knobs in the cab. Milton Engineering have just brought out a lovely regulator arm for Edrig/Caradoc.

Then there is the DJB Engineering whistle - must get one. I will have to find some room for a third servo in there somewhere!  and that will be the feature of the next article. This article is now live and can be found by CLICKING HERE.
