Hi,
I am looking at control options for my 1/8 scale locomotive. I am
interested in the possibility of controlling it by R/C. It isn't your
typical locomotive, though, in that it is ten feet long and weighs
nine hundred pounds <g>. In other words, it is a "ride on" locomotive.
I have looked at some of the conventional R/C systems like Futaba,
etc. and they are simply much more sophisticated than I need, with
the exception of eight or nine channels.
What I need is a simple system, preferably one that I can mount the
transmitter in a sturdy handheld case and install the necessary
controls myself. The system would require four high torque servos,
one or two on/off switches, a couple of variable pot equivalents and
one off/on/momentary on switch for the ignition.
Is there a manufacturer that produces something that might work or a
couple of manufacturers whose products I could cobble together? The
electrical source is a twelve volt automobile battery.
Regards,
Britt Harrington

'Fraid I can't help with your requirements (other than to say that
4-channel land-based FM radio sets are about UKP120 from either Futaba or
Hitec), but just thought I'd point out that there's a potential problem
with R/C rail.
Apparently intermittent metal-to-metal contact tends to scatter radio
waves, and the action of steel wheels bouncing or skittering at all on a
steel rail has the potential to cause problems. I've never tried it
myself, so I don't know how much of a problem it is, or whether you could
cure it with some sort of sliding earth contact on the rail or similar, but
just thought I should mention it...
