I believe RCLogger uses off set gear motors from Servocity for his dozers (check his thread in the construction section). Here is a link to the motor (I think):

thanks ken are they geared do know

Some of them have a worm gear on the shaft. That is about all I rember as it has been a very long time since I have had one of them appart.

Also check "surplus center" sometimes they also have small air and hydraulic cyliners for a few dollars.

They are located in Lincoln Neb

Hey Trevor, if I remember correctly, Greg's D8 weigh's around 28 lbs? So if you double the torque of his motor's, then you should have a baseline starting point for motor choice's. Cheer's, Neil.

I wasn't suggesting he use those motors, i said there are plenty like that, obviously he would have to find one's that meets his specific needs

also i do not know who greg is or anything about his D8 (guess i haven't read everything here yet) i was simply making a suggestion

sorry about the misunderstanding

have you look at some of the new 11.1 volt drills ,you could check your local pawn shops and find them cheap or yard sales , plenty strong and even a clutch you can adjust to not break tracks lol
