Foxy: Ok, so then I don't need the ESC that you listed?
SyCo: I don't have a drive chain. I'm thinking you meant is "drivetrain". Yes, all the gears (including spur) are plastic. The diff internals (Bevels, spiders, and outdrives) are all metal. The actual diff gear itself is plastic. Also, the dogbones, drive cups, etc are metal. The hex adapters are plastic though. I have plowed snow with it before, (Had a terrible heavy, sheet metal, bent plow that I used) and didn't had any trouble with the drivetrain. That was using the VXL 3500kv BL sensor
less motor that cogged. So now, after building a new plow, I found that I can't have cogging, it just won't work for me, and that this year, it's going to work. I DO plan on plowing snow 1-2" (maybe 3") deep, so I'm serious about the torque. Thanks for thinking of that though.
If you have anymore thoughts, feel free to post!
