But I am back with this direct to diff outrunner idea as we now have a good solid programmable 6s esc (MMM) better lipos with higher c ratings, and the cost of motors is slowly going down. So this is getting more viable.

But we still do not have any shock protection, or do we???

New idea, make the outrunner mount absorb some shock. Well not too new, I said it on page 1 3+ years ago...

But I have figured out a way to do it. Imagine the pressure plate on a manual transmission clutch. It has springs setup radially around the drive hub to absorb some shock by allowing the pressure plate to move slightly in the same direction as rotation. The springs are strong and stiff, but will give under heavy loads and provide some shock absorbsion. Or for you motorcycle guys, the cush drive on the rear wheels of a chain drive bike.

Same idea, just between the outrunner and the mounting bracet to the chassis. Imagine 2 disks, with springs setup in recesses that can act on each other. One disk mounts to the chassis bracket, and the other to the outrunner. The driveshaft from the outrunner would have to go thru the center, and both disks would have to be held together solidly to support the weight of the outrunner. But when shock was transmitted thru the tires,diffs, back to the motor this would allow the motor to "twist" a few degrees and absorb some of the shock.

So whatcha think bout dat?

use a centrax clutch, or just mount the motor on rubber bushings, or make a 2 peice motor mount designed like an old servo saver to take off the shock loading

just some ideas for you linc

Just what I am thinking. I have the design mostly worked out. Pretty sure this will be in an emaxx, as I have a 3905 roller with lst diffs just hanging out.
