Default How do you snap axles?

Hi. I was wondering how you guys can "snap axles at will". Do you do it by applying more throttle to get out of a stall and the torque exceeds what the drivetrain can handle? Or do you do it by trying to turn when going on flat ground at fast speeds and the stress gets too high (since the diff is locked). Or does this last case just make your truck flip instead?

I'm trying to figure out how fast is too fast for a locked diff truck on relatively flat paved ground (before it flips or breaks due to the imperfect travelling in a straight which places extra stress on the axles when the applied power turns from speed into torque since the diff is locked). 10ft/s = 11km/h = 7mph is the top speed I think the setup I am looking at will get. I'm wondering if it's ever safe to travel at that speed with locked diffs.

Simple equation...

Torque x Traction = Broken Parts

Driving around with locked diffs is just going to mess up your turning radius. The only way to snap shafts easily is to bind something up and thottle it.

EDIT:damned slow typing...

Actually, if you take the best care of your truck ever, and just like to drive it rough because it is fun, you could break an axle. It is usually when you get into a really tight situation and try to get out with your wheels jammed that you break your axle.

i found out it is not worth it to try to get out of a area when my tires are binding, i am going to start setting my slipper in extreme situations it will let up some!

THere are no slippers for Clods right? Maybe I should replace something with a crummy plastic gear so I can choose which part will break first (this is actually for a robot, not a crawler, and to get the crawling torque needed and maximum speed on flat ground, I need to use a motor that will be able to easily break the shafts if it's going at top speed and hits a bump or something and all that power goes from speed to torque.)

I tend to break shafts when I get a wheel stuck under something and I decide to try to use the truck to move a 60# rock instead of being smart and backing up.

i think usually its done very carefully while trying to avoid breaking somthing.

Tires bind up, you don't let up on the throttle quick enough and something has to give.

Torque + Traction = Rig drives over obstacle
