I strongly recommend against this idea, for the following reason:
Once you fully discharge the 7 AH battery, the 18 AH battery still has
half of full charge, and will continue to deliver current through the
discharged battery; this will, in effect, reverse-charge it. The
effect is similar to conne
I've examined one of these track links and the drive sprocket. The
track itself looks great, but the plastic pin seems a bit fragile for
the kind of heavy use the active guys give their gear; I'd replace it
with a steel rod. As for the sprocket, it seemed to me to be a bit
lightweight, the teeth lo

Alas, you won't get precise movement tracking with a tracked vehicle,
because the tracks slip when turning, to a degree that depends on the
surface they're on. You'd get more accurate (but still not totally

more casters, as the whee

Ok, Since receivers have a voltage output of 3-7v roughly, does anyone
know of a way to convert that so that you can control a 12vdc relay?

relatively simple; otherwise, one might as well pony up the cash for a
Spektrum DX6. Any details on the work in progress?

Let me add my voice to the chorus of praise for your craftsmanship.
Wow! Those tracks are quite incredible, and the chassis looks
excellent as well. It will be quite fascinating to see how the vehicle
looks when completed. (You'll need an external antenna for the radio,
of course)

My solution to the problem was to mount a large pulley (custom-made
from sheets of thin plywood) centered under the turret (which rotates
on a lazy-susan), and drive the pulley, and thus the turret rotation,
with a toothed belt (salvaged from an inkjet printer) and a small
gearmotor with a toothed-
Two words, there: Nylon Washers. Won't be very visible even in the

That's a stunningly simple and elegant suspension system, I must say.
Of course, you'll want much stiffer springs on the first and last
bogies.

Looking back on the hull construction process of My Tiger II to date,
I think that if I were going for repeatability (and Rommel only knows
why I'd need more than one beast of this size unless I planned to
sell'em, which seems an unlikely proposition),
Crunchies!

You know, it should NOT be necessary to use a laser for this purpose.
A decently high-brightness red or blue LED (and there are some VERY
bright blue LEDs out there) with a lens of reasonable diameter can be
used to make a collimated beam good to a few dozens of meters;
modulate it at 10 KHz or so
