It all comes down to gear mesh and slipper clutch settings. Traxxas just came out with a kit to run the Revo slipper set up on the older Maxx, you might want to look into that.

I also think you should leave Jim and Jack alone....Crown will make you see things much clearer.
 
How tight is your slipper? If memory serves, you tighten it until the spring is fully compressed, then back it off 1/4 turn.

It's a 2.5 maxx right? The 3.3 maxx has a clutch like the revo.
 
Is it a 2.5 chassis with a mid-block bolt in or is it an extended chassis with a real big block? The RCS won't work with the 2.5 chassis. The clutchbell/flywheel for 1/8 scale is too long and requires another half inch or so between the trans case and the engine.

You can also try diff bearings instead if slipper pegs. I'm not sure which ones are the right size though.

Your only other alternative is to go with RRP's dual disk slipper assembly. Or a steel spur... You will need a new CB if you go with steel though as the stock ones are too soft. RRP makes all three. The dual disk slipper (replaces pegs with pads), hardened steel spur/hardened steel CB.

If you go with RCS steel spur, the HPI savage 3-shoe flywheel and shoes works well with the OFNA hardened CB's and that spur. That's what I ran on my BB maxx many years back.

Regardless how you look at it, it's going to take some coin to get the problem to go away. Personally, if I had it to do over again, I'd still go with the RCS spur, OFNA bell and HPI 3-shoe flywheel w/teflon shoes. It was a worry free setup after that. You get all the benifits of a 1/8 scale clutch, not just a stronger spur. Better off the line, less overheating of the CB, less wear/problems with CB shoes.

Here's a link to the RCS spur:

And a link to the RRP dual disk and steel spur:

Going with the dual disk slipper might be cheaper in the short term, but you will still have a 1/10 scale clutch on a 1/8 scale engine. I had issues keeping clutches from melting down on me.

Huh... I don't think I ever saw that setup before. I've seen a lot of BB maxx's, but nothing that used the short chassis aside from a weird new era kit that mounts the engine 2 inches off the chassis.

You should be able to use an 1/8 scale flywheel/clutch/cb and the RCS steel spur then. Unless you had to modify the crankshaft so it doesn't hit the trans.

With an 1/8th flywheel/CB on it, it will come about flush with the end of a typical BB crankshaft. If you had to grind yours down any to get it to fit, then your stuck with 1/10 scale setups.

Or, you can drop in a tmaxx 3.3 trans/slipper. The slipper on those is like the revo which is pretty durable. No more pegs.
 
How much longer is the wheelbase with the extended chassis. Must be quite a wheelie machine?

But yeah tighten your slipper,and if it's already tight, maybe ease up on the throttle. That's a butt load of power you have.
