Re: Motors to replace the EV Warriors [TANKS]

[himself-at-adamwells.net]

Well, I had originally decided to build a Panzer II, and I ordered two 12 volt 
Dewalt motors with matching three speed gear boxes from robotcombat.com, along 
with drive shafts to fit them from teamdelta.com. I have to say that size wise 
drill motors seem like the ideal solution for powering low profile tanks. I 
decided to steer clear of the 24 volt versions, since their increased power 
comes with a doubling in battery weight and I was shooting for a fully loaded 
weight of 50 lbs with the Panzer II.

I've since decided to drop the Panzer II idea for a 36" (1:7.25 scale) T-62, 
since it'd be a more well rounded tank for my first build (40/4 rating, 
compared to 30/2 rating). So, I guess I'll find out soon enough if the 12 volt 
drill motors can power a MBT. I will point out that the 12 volt DeWalt with 
it's gearbox (450 RPM - 29 foot lbs) seems to have more potential than the EV 
Warrior on 12 volts with the 1:9 ratio (246 rpm - 32 foot lbs)  that seems to 
be the standard. The DeWalt could be geared down to the same RPM and be putting 
out over 50 foot lbs.
