Personally, I think a self-flipping device would be much more useful. Sucks to have the truck really far away, it flips over, and you have to walk over to tip it back over...

Ha! With some of the crazy high torque high voltage servos that are coming out a "flipper" seems plausible:yes:

Actually, I was thinking more along the lines of using the motor and gearing of one of those cheap cordless screwdrivers set in high-torque/slow mode. Even tearing apart a brand new one would be way cheaper than a servo powerful enough.

I call it the walk of shame. Some big lots I bash, it's better to hop in the truck and drive to go flip it over. Anymore I save the crazy driving for the return side of the loop. Sometimes it flips, slides and cartwheels to a stop right at my feet. So at least it looks like a I was intending to destroy my r/c.
