At the motor output? The conventional control signal is a 1-2 ms
pulse every 20 ms. It would be simple to convert the control pulse to
an output pulse at the same rate,
My Hitec servos show 20 millisec pulse repetition period.

have any direct experience with the kit but I know Frank built a
couple and had issues with them. Maybe he might elaborate.

Would response time be a problem for this method?

Now that, Steve is good intel! I am VERY interested in the TLE 5206-2
driver. I am ready for the Paul Harvey, (the rest of the story) whenever
you would like to post it. A simple (very simple) diagram showing what to
connect where and perhaps a socket part number would be useful. I have a
I was researching better steering and found this youtube video on a
similar idea of using a wiper motor to steer with servo feedback.

Steve,
The SSR option looks quite interesting. How would this be coupled with the
hacked servo? I've only seen schematics for H-bridges, how do they
interconnect?
I may in fact go with the commercial H-bridge. At best I would save $20
building a MOSFET H-bridge, even less building one

The Pololu board would not work to amplify the current capability of
a standard r/c servo. The Pololu board is a bit to intelligent in
that it has it's own processing capability and determines motor speed

You also need a mechanism to handle the jolts and bumps without transmitting
the shock to the servo (or gearmotor).
Agreed. A thought I've just had is that since the system we are
discussing involves a

Steve, you must have been reading my mind. I was just thinking about a
solution for the BT-7's steering. Have you tried this? Seems like a good
choice for large wheeled vehicles!

I've been wanting to do this as well for a project. Every time I look into
it however, I keep running up against the Tecel website, which turns up an
access forbidden message on the D200. I make a note to call or look into
it further, then other things come up.
I have several motors I could use

I have not personally tried this yet but I see no reason why it will
not work well. Some possible gearmotors for steering our armoured
cars could be:

Ah, thanks Steve. I'm sorry, I hadn't read through the bottom of your
