Heh...bad idea!(I would never do that)
Good idea about the slipperential.You can also use a b44 center diff(not sure which is cheaper)but I don't know about the durability of this mod.

Tight gear mesh can heat up a center diff. But so can a crazy huge power plant! haha....

Ok just to update, forget it! this trucks wheelbase is just too short for 4s, I know this is really an 1/8th buggy setup, so not surprising really. I dropped the diff oil down to 3k and put the punch control to 90% (first tried 30, then 50 , then 70) and STILL cant stop the front from lifting, problem is it happens at about 80% throttle where its already going at 40mph or so, so once the wind gets under it, its gone, flying through the air.





Dog bones are UJ's both ends, they are 1/8th uj's I made a collar so I could fit them to the front and rear diffs, the shafts were then cut and welded at the right length, the center diff is obviously 1/8th, not the original crt one.

If you were driving it only on road,you could set the ride height lower (lower center of gravity)and prevent this from happening.(worked for me)

Making a new chassis, going to put the motor at the front to tame the wheelies.



Standing the lipo up so I can have straight prop shafts, 10mm longer than before, dimensions are more or less that of a Rustler.



milled some areas to loose some weight.



put the servo flat as there is room now. Just need to make prop shafts up.

I have been working on this quite a bit, have now switched to a mamba max pro esc with an Orion Vortex 8 (2050kv) motor. Its the motor form the Kyosho Inferno VE, only a 2 pole so less torque BUT im going back up to 4s . A Zippy 4s 5800mah, made up a wheelie bar but in this test run the ground was damp and not much grip to be had.
