Re: Cheap drive motors? [TANKS]

["Mike Calvi" <mikecalvi-at-gmail.com>]

try these instead DCM-231 (from the same site). 

they have a longer drive shaft and it is slotted so it fits perfectly into a Powerwheels gear box.

 

While i am not building an RC tank per se, I am building a tank type robotic lawnmower and using the powerwheels gear boxes.  Since the weight will be significantly less, I am not too worried about the plastic gearing.

I bought a couple of these motors a while back:

3-24V range, $3.50 per.

I didnt buy them for the tank. they were going to be used in a 1/144 battleship when I got around to building it.

I have since reviewed the specs and even saw a website for a guy who upgraded his Powerwheels with them.

I figure that a 3:1 gearing will give 5-6 mph at 12V.

I am not good with specs when it comes to electric motors though.

Any suggestions?

If worse comes to worse, would running 4 of them (powering the "idler" in addition to the drive sprocket) make a difference?

Thanks,
