I did an Athearn R/C HO scale crane three years ago using Deltang R/C board.

OK then, let's see some more operating cranes, etc. How about an operating crane (Brownhoist) that not only works but is capable of running by itself from job to job. I have seen such cranes do "double duty" as switch engines-in a pinch I suppose. Might make for some interesting operations on the layout!

The running gears were the same type of gear motor (Polulu have better starting characteristics than the cheap eBay ones) driving through a pair of plastic bevel gears to the back axle.

I finally built myself a four-joystick transmitter to drive this thing, based around a DelTang TX. It now handles very well and reliably.

Hi Giles.  Can you tell me a little bit about how you built the joystick transmitter using a Deltang TX?

Hi Rod. Given that a Deltang Tx module is more or less the same as any DSM2 stick radio innards, you would probably be better off simply buying any DSM2 stick radio.
The most difficult thing to build are the gimbals that connect the sticks to the controlling pots.

Tony, I am only familiar with DT tx / rx.  Some DT rx models can be controlled useing a DX3 tx.  I am going to put R/C into some 1:87 vehicles.

Can you tell me anything about DX3 txs'?
How would I choose a DX3 transmitter over a DSM2 stick transmitter?
