Axle suggestions?

[jerry56]

I think the space between your frame rails might dictate what you use...
The heavy duty planetary gear motors are over 100mm long but they have the torque your going to need. The 90 degree worm drive motors might work. Or you might have to machine or somehow build a gear box.
if you have room you could look at 550 80 turn motors and a 3 or 4 to 1 gear reduction feeding a crawler axle but I'm thinking some type of direct drive to the wheels would work out best....
I'm looking at some of the same limitations for my Tournarocker and tournadozer
