Complete unmolested X-factors are getting scarce. That is not to say VALUABLE... just scarce. I've got one, still mostly unmolested for now, as well as a "bazturdized" electric version.
There are few hop up parts left for it. Everyone who has 'em is hanging onto them 'cause these things stopped being made a few years ago.
www.xtm-dealer.com is my favourite place to shop for my XTMs, and John barely lists anything for the X-factor anymore. You may be able to get some bits from there or from
www.hobbypeople.net, but they're getting rare.
If you can get or build a wheelie bar, do it. These things are hard on the rear muffler!
As for bodies, I'm not sure what fits. I've got an old school hardbodyz cage for mine and have welded on body posts for it, and have a Pro-Line F650 on it. Anything that fits the LST2 or MGT should fit the X-F, but don't bet the farm on that: I said "should".
One thing that I'm contemplating doing on mine is flipping the diffs to spin the wheels backwards and moving the steering servo to the "rear" axle, so that the truck becomes a front engine instead of rear engine. Then using a buggy pipe should be pretty easy and with the improved weight distribution it should handle a little better. I can also get rid of the recoil at that point and use my spare LST2 spin start mechanism.
The axles are pretty weak for a high speed vehicle, and they tend to break (especially in the cold). You can get rid of the upper link mounts and mount the uppers on the axle, which besides eliminating one weak point has the added benefit of more axle/chassis clearance.
I also switched my wheels for 17mm hex drives and installed some of my spare Mammoth ST hubs. You could go right to the Pro-Line 23mm hubs if you like, with the proper adapters. Even LST2 hubs will fit if you want to go that way. I'm using some XTM MMT wheels/tires I got off e-Bay - they're a bit narrow due to the high offset of the MMT wheel, but they look just fine and hold on MUCH better than the stock junk.
I don't get much drive time with my X-F - it's a bit tough to drive because it's so bouncy & top heavy, and being that it's pretty fragile and parts are getting tough to get, I kind of take it easy. Still, it's such a goofy mother that I had to have one.
