[TANKS] Re: Here's the first video

Both 18ah batteries and one 4ah battery weigh in at 2 stone even.  And
a bushel is not a weight measurement, even in Jersey. Working on the
hopper this week. Looks like we'll be operational on the 29th.

RE: [TANKS] Anyone tried the ESC "RoboteQ Speed Controler?

[Guy Gregoire]

Hi Chris,
 
Its a good idea of course to protect circuits inside a plastic box, I just 
appreciate the design
of Roboteq that have his circuit well safe inside an aluminum case with wings 
to turn the
container as a heatsink so it dont even need a fan to keep it cool.  The RS80D 
I was using
was in plastic, with bigger opening than needed with in extra, a big fan on 
top.  My ESC
smoked after a miss connection " my own fault", but this said, why not, when 
its time to
buy a new ESC, give credit to a "seem to me" better design.
 
Also as I mention before, the third channel for accessory seem very accomoding.
 
I might be wrong and forget important things, its why I ask opinions before I 
spend
the $ 500.
 
Greg.

RE: [TANKS] Anyone tried the ESC "RoboteQ Speed Controler?

[Guy Gregoire]

After 4 years of loyal services my RS80D smoked, just like yours Derek.  ESC is 
an expensive part of a tank and I
want to buy a good one to do many years over it again.  Yes Vantec is an old 
tuff one that I might go for.  On that
Roboteq there is a thrid channel provided I can use for the door actuator and 
it seem pretty well build with no open
space for a little screw to go in and short something.  I will continue to look 
around before ordering as once its done
you have to live with it.
 
Greg.

Yeah, no experience with them.  I have used the Vantecs, IFI Victors, and the 
Robot Power RS80D.  All were nice controllers except the RS80D.  Mine smoked, 
but there are people that have had better luck with them.  I still have the 
RS80D and maybe someday I will try to repair it.  The Vantecs and Victors are 
pretty bullet proof.

[TANKS] Re: Model T Experiment

[HV]

I was away yesterday, but sorry to see the thread died, as I thought
Frank's questions were worthy of serious responses. I'll offer a
couple of thoughts toward answering the questions.

I have been only peripherally working in the hobby on and off,
starting with building a minimal-cost wheeled chassis, then going off
on a tangent and building a minimal cost and much smaller robot. Both
of these were considerably less expensive than Neil's 750-950 UKP
estimates, if I consider only the final parts and not the parts that
were tried and found wanting.

I wanted to answer the question of what is the smallest/cheapest
vehicle that I could run in my backyard. I figured that the 1/16 scale
tanks were too small, and that grass would foul up the tracks, so
something a bit bigger with decent ground clearance would be needed.
Some lessons learned were that a small wheeled vehicle of dimensions
w= 15", L= 12", 6" wheels, 4" ground clearance can operate on some
relatively benign outdoor terrains such as lawn grass, gravel, dirt,
quite well. This vehicle used four $10 motors, very low RPM, so the
thing is very slow, but very CHEAP! A single 7 AH battery easily lasts
an hour. I guess it is similar to an RC rock crawler, but simpler and
cheaper. However, most people are interested in tracked vehicles,
including me.

Earlier this year I started work on a tank. Like my previous efforts,
it is more of an experiment in reducing size, weight, power, and cost
than anything. I was therefore gratified to see that the Pitellis were
thinking on the same lines. I spent/wasted a lot of time selecting
what I thought would be the simplest-to-construct tracks. I wound up
choosing hinge tracks. I chose a tank that has narrow tracks (Russian
"Sprut" assault gun) because at scale, 2" hinges are about the right
size, and these smaller hinges weigh less. I wanted to use plastic
hinges, but couldn't find any that would work. I'm still not happy
with this choice though.

In my opinion the track/drive system is the biggest hurdle in building
a tank. I would vote for that as the core of any kit. Some more
thoughts later. Got to run.
