I was just wondering what the cheapest / best motor gearbox wheel combo is these days. I was gunna just go red wheels + drills but I am rather reluctant to pay $30 for a drill.

at supercheap they have 12v drills for $20.

and they have some 2 speed 24v hammer drills for $75 as well andrew, they look like the ones you used in the game.

schweet, will get to a supercheap first chance and have a gander

Found the stray pinion tho so besides a plastic fan in one motor disintergrating and falling out in pieces everything is there to rebuild the drives

On another note anybody know where you would go to get largeish o rings, for my beetle i wanna get large o rings and lathe a groove into some ali stock as pulleys

thanks

JW if any of you might understand how this transmission works.

I think its called a regenerative steering system,

very cool is that the kind they used in the first churchill tanks? cause i think that was called a dual differential gearbox or merit brown something like that. according to this crappy tank book anyway.

Apparently the unit is based on an actual Leopard and in that assortment of gears are 3 diffs, This would be so good, tank steering for tanks actually sucks.

Electric lifter control

I just realised I don't have much of an idea about controlling the position of the arm on my electric lifter sportsman bot. It needs to turn the arm about 90 degrees and is capable of doing some real damage if it overruns it's limits. I don't really need full servo control, something with limit switches would od just fine.

The 2 ideas I had were a jumbo servo controller, which would work with minimal setup, or a regular Victor ESC and a custom weapon controller with limit switches and a MCU - any other ways to do this?
