Ted,
For those of us who have Stuart's....Thanks for getting busy with
them and showing a "slowpoke" what can be done...I for one am ignorant about the
electronics but I can copy a system if presented on a "low" enough
level...
Good Luck,

Subject: 1/6th RC Stuart drive
electronics figured out
FYI, spent an hour or so this evening and figured out the
Stuart drive electronics. There's a 22 pin IC on the main board
labeled 8A991AP that's apparently an RF decoder. I was able to probe
out the pins that enable the right forward, right backward, turret left,
turret right, MG & cannon 'fire', etc., etc. This'll save a lot
of time interfacing a standard RC system to the tank as all the drive
electronics can stay stock and you still get the sound effects.
Pull
the pin(s) positive (high) and you get the resulting movement together with
sound effects. It'll be pretty simple to interface
to servos/microswitches. I'm gonna play around with some logic to see
if I can figure out a joystick mixer. If not I'll resort to 4 small
SPDT relays and a diode/relay mixer. I might even incorporate a
little RC switch circuit and 555 timer to toggle the cannon 'fire' sound
and resulting brief recoil (drive motors kick back a little) AFTER the
paintball marker fires.
Anyway, ends up being pretty simple. I'll
post out on my website when
it's complete.
Regards,
