Doug, these are basicly the same motors that Mike used and burnt out. Steve 
suggested venting them.  These motors are air tight, not a hole in sight.

Re: [TANKS] Re: AMX13

['Mike Mangus' via R/C Tank Combat]

the S-tanks motors didn't burn up.  They did severely overheat though due to 
too high gear ratio, running at partial throttle settings, and basically using 
the wrong motor for the gear ratio.  

If building the S-tank again, I would probably ise the sprocketed geared motors 
Steve found and add a sprocket to the drive hub to reduce rpm even more to the 
tracks.  That would let the motor run at full throttle and multiply the torque 
to the tracks.

Don't do it ! I'm not aware of anybody in this hobby overheating a motor. Has 
anybody done it ?

Motors should stay sealed. There's a lot of dust, dirty, grime, and paint at an 
R/C Tank battle. The last thing you need is any of it getting in the motor. 
Drilling vent holes is too much risk and too much effort for no gain. If you 
feel strongly, use heat sinks and fans, but leave the housing in tact.

On the idea of venting the motors, think its possible. Cracked one open this 
afternoon to take a look. There is about a half inch of space between the 
magnets. That should give enough room to drill a series of 1/4 inch holes along 
the length of the side. I think i can maybe even get a few holes around the end 
too.  Did not drill any today as winter has eaten my shed.  The motor even 
worked after i managed to get it together again, impressed with myself ;).

[TANKS] Bare Bones 9K22 AA Chassis

[Tyler Porter]

Hi, i'm totally new to this, but i thought i would share my bare bones test 
chassis, for my future 9K22 Build , as it sits right now it weighs about 
59kg, at ≈4.5 feet long and ≈2.5 feet wide. it likes to do monster truck 
style doughnuts if only one track is powered. it runs off of a single 08 
civic car battery, and 2 winch motors that have had the planetary gears 
modified for higher speed, it is completely, (minus the 2 tension arms), 
made of steel. each track is about 25kg, i welded the steel plates directly 
to the roller chain and they have held up to quite the abuse so far only a 
few have come off in extreme tests,
Thanks for your time,
Tyler Porter

Re: [TANKS] Re: AMX13

[srwh74rn]

Sorry mike, my mistake. My starter motors are exactly the same (looking at 
them) as the ones Steve found. As for set up, i would too make use of the 
sprocket to run chain to another larger sprocket to reduce rpms at the drives 
and improve torque.

Re: [TANKS] Re: Expanding the S.C.C.'s Arsenal: M3 Halftrack Build

[Caleb Smith]

The motors came on Monday.  I'm pretty pleased with them.  They are very 
easy to tear apart in case they need cleaning.  
One of the things that concerns me though, is that the main reduction gear 
is plastic (nylon?).  I hope it will take the torque. :)  The 
main difficulty with these motors is the shaft.
It's threaded, and I am a little stumped on how to mount the drive sprocket 
securely to it.  I would appreciate any ideas/suggestions. :)
Here's a link to the motor.
