Worlds Fastest RC Car Challenge take 2.

Well, the Slipperential would definitely help keep your front end down. This means you will run 4wd. If I recall, the new rules still do not require 4wd... I think in the end ir would be better to have a solid center axle driving only the rear wheels (or even both wheels) as it will ensure that the motor power is not wasted.

For top speed purposes, I would say a center driveshaft with a slipper would be the best. The slipper would protect the drivetrain, but there will be no gear reduction and less rotating mass with just the solid center driveshaft. If you don't understand what I mean here, I basically mean a slipperential without the differential.

John, I will be going this year as well, though I hope to enter a truck this year. I am going to start working again to build up funds.

I believe MetalMan will be entering as well...maybe we can make up team RC-Monster?

With a huge amount of power the center diff will not stop wheelies. I do think a center differential is the way to go. The center diff will weigh less and have less rolling resistance than a transmission. Also you can have some crazy high gearing with a center differential.
If you will be using 2wd or worried about power loss just get a spool for the center diff. Ofna makes one for there center differential.
My trucks were always faster with a center differential. Not sure why, could have been the less rolling resistance or the higher gearing.
