Well, I've started working out the future layout for the hyper. I managed to find a center diff in my spare parts that will take a nylon gear (ofna ultra mbx iirc), it's longer than the hyper 7 but that's fine as I was going to relocate the CD anyway.
I mocked up the 1518 with a trimmed toilet paper roll :-) I plan on either making a diff/motor mount, or buy the RCM universal set that puts the motor over the diff, but that would be a large portion of the budget. Either way I want the motor centered over the center diff.
I found a 16mm x 6mm dog-bone to put the CD right at the rear diff, and with the spur gear towards the front of the buggy it would locate the motor just above the center of gravity on the chassis. I'll either find the correct length front driveshaft or build a 2 piece with a carrier bearing and cva.
I could locate the batteries on either side of the chassis and adjust them front to rear to change the weight bias... That's the way it's planned today anyway
