Kyosho & Tamiya Rock Crawlers

actually a worm gear can back drive.....iv done it

but oyur right on a rig like this, you can do some precision driving. But i really hope the casing is tough! cuz worm gears are rough on housing

I have a design for the axial crawler to use worm drive. I was going to use steel for the tubes and center section, mainly cause I can weld (and have a $1700 welder) plus they will be very sturdy, can be made more compact, and the weight is where crawlers need it, low. Also the steel parts should hold together better under the load of the worm. I will need some big bearings, and plan to offset the gears to alow for better servo mounting. Plan to use stock axial c hubs and knuckles. Axles may be custom, or I will integrate some sort of existing cvd axle.
