Can a slipper clutch be added to this system? I would like to like to get this as rugged as possible. It is a great truck as far as performace especially with a Lipo, all of the shaft damage was done with NiMh battery. The shafts didnt break but instead the pins in the universal cups fell out. Since I have upgraded to all aluminum chassis and a-arms the truck itself has held up really well.

It is still my intent to build a buggy bumper for you, I just have not been in the shop lately. I have the specs now for the frame and will do my best to keep it low profile since its not a Monster Truck. <br type=''_moz'' />
cool...
I didnt have much issue with dogbones on my volcano or my tornado. I mean, a dogbone every 10 pack or so would snap (one of the ends) but thats not that bad IMO. Had many a traxxas model that had the same issue with their driveshafts.

The ESC punch control will still help, even if you run nimh packs.
As I said, I didnt like the CVD upgrade parts. I went back to dogbones. I found that putting nitro fuel tubing in the cups and setting up the shocks for lessor angle on the driveshafts (lower ride hight) helped alot.

There is no way I know of to add a slipper clutch. MAYBE, with a good deal of modding, the slipper setup from a traxxas slash 4x4 could be made to work. Youd need a 32p pinion to match new traxxas' 32p spur. Im not sure if there is even enough room between the diff and motor mount to put a slipper.

taking a trip to a hobby shop and comparring the epx's dogbone to other brands may reveal that another model out there has the same length/ball size and could be a stronger dogbone.

If you havent owned a traxxas Brushless model, you cant apprecieate the dogbones on the redcat stuff. The traxxas slider shafts tend to twist and then snap off. Over the years I must have replaced 30-40 of these! And the only upgrades are made by MIP and cost $50 for the 2wds...$100 for the 4wd models. My buddy bought all 4 MIP shafts for his slash 4x4....and broke a front MIP in the 1st battery pack! Man was he ticked.

The nitro fuel tubbing really can make a difference. Without it, the dogbones move around in the drive cups....metal hitting metal and wearing each other out.
