9 times out of 10, the problem with the belts is oversized diff pulleys OR the belt not riding on the pulley correctly. In one case, a guy actually had Losi pulleys that were deformed causing the belt to never ride correctly. I always install and let the car roll without a motor in it. That helps me to know the tension is just right and the belt is seated correctly. Others are correct, the belt does take time to break in and stretch. However, stretch is limited as the belt is Kevlar re-inforced for longevity.

I just ran out of my stock, but due to renewed interest I will be getting some more. It's just taking longer than it normally does because of work obligations. I also don't log in on here as often as I used to. I've still got other stuff in the development pipeline if people want it, but the market is shrinking as people throw their stuff away.

Broke the XXX-S out today, it had been around 3 years since I last drove one. The car was a beast on carpet in VTA, I really forgot how much I like driving one. A win in the class was a nice reintroduction to active duty.

fingers crossed that jhwnissan and fathead get us some nice new bits for these old-but-capable cars .

Should have belts next week. Will let you guys know. I'll be getting belts only 2 times per year after this. That'll make my life a little easier which should be less stressful and I should be able to keep you guys stocked. (It'll also give me some time to work on that plate chassis XXX-S.)

Belts are back in stock and I've got some spare parts around too if anyone is interested.

Or just tell us here. Also, to repeat myself, what are you folks using for diff rings and thrust bearings, because old stock doesn't seem to exist.

Honestly... if you want to run a XXXS these days, you have to fully commit. When you see rollers for cheap on ebay, buy them for the hardware alone. The 20 to 40 dollar cars. Usually don't come with a belt, are dirty, and sold by the guy who "doesn't know what this is cuz he's not into RC cars" or whatever. Take the car and break it down for parts. That's what I've done, along with other resources I tend to keep to myself.


You're not going to find old stock of thrust bearings under the XXX-S name. All XXX branded vehicles used the same ones. XXX buggy and truck, along with the Sedan. Same with diff rings. Look hard enough, and you'll find them.

Sounds about right, lol. The obvious issue with these cars has been the sourcing of belts and adapters, though that is being addressed thankfully.

You do have to be willing to look and search a bit for parts, but it is worth it. Just don't be that guy that spends more time buying / hording parts than actually racing. These things were meant to run, not become a collectable obsession. I've been very happy with mine in VTA, I keep a small supply of extras with me but honestly nothing ever breaks!

My VTA car is a monster. In the last 6 months I've broken very little. That car only costs me in tires, generally. I've gone through a couple c-hubs, and bent an aluminum cvd, an a-arm once when I was have a really bad night. Otherwise, it's a tank. Best part... it's an extremely consistent, extremely fast car. VTA is the perfect speed for the XXXS chassis, and because of weight restrictions no other chassis really has a benefit over it.

I've been trying to land a trinity spur adapter, but $75+ is not worth it. As long as I keep finding 64 pitch 108 spurs, I'm fine. We have a 4.5 FDR rule at our track and with the 108 have I have no problems. The 118 works as well, because there is such a large throw with the motor cam for just about any size pinion.

I'm still racing with stock belts, but I have a few of the later re-pop belts. The stock belts have far less roll resistance. But, I've gone through two of them.

I race 2 XXXS cars, twice a week, every week. It's taken some creativity for sourcing parts. Since the cars were in production for quite a while, it hasn't been super hard. There is always someone at the track who shows up saying "I used to race one of those, I think I still have a bunch of parts laying around".

I do have two collector cars as well. One is a bone stock first edition car, and the other is first edition with full graphite upgrades (first edition graphite chassis) along with all but two pieces of red aluminum upgrades. The spur adapter (ugh..), and the front body posts.

Once I get Fathead's spur adapter in hand, I will give it a good weekend race test-session. It's pretty cool that he has taken up the task of trying to make these for us!

I'm on my third XXX-S. The first was a RTR that I put a legal 27t in, and won with my first time racing it.... it had been at least 10 years since I wheeled a car so I entered novice sportsman. Ok, so it wasn't the worlds biggest challenge , but either way it did the job and I had a soft spot from then on for it.

Next was a graphite car with all the MF and IRS bling you could throw at it. I parted it out and sold my stock of spares after a XXXS won a big VTA race (national), at the time there was nothing but the last of OEM parts (belts!) floating around... and people were buying the cars / spares up like crazy after the chassis made its mark. I made some good $$$ out of it all. I sold 3 original MF adapters for 40-50 a piece.

The current car is nothing special, a Stifezel chassis and a mix of graphite / rtr parts. A few touches of bling are present, but it is far from a gleaming shelf queen. It is my VTA workhorse and it has clocked in for work every time I have busted it out.

The only reason I was able to get it going again was because I found another MF adapter for $8 bux shipped . But if all goes well, the FH adapter is going to make dusting these cars off that much easier. As long as I can keep one going, I will.
