As a side note, I have always setup ring and pinions in RC cars exactly how Kyosho now states in the ST-RR manual. Its just something you do with actual real car diffs and transmissions that most don't know. Most brands don't mention diff shims at all.

The ST-RR instructions went into details about how to correctly setup the ring and pinion backlash. It mentions about the break-in period also.

Here's a link to truggyracers-there is an excellent step by step in the build tips if the link does not work. BE SURE TO PUT SHIMS ON THE PINION GEAR, OR IN BETWEEN THE PINION BEARINGS. I purchased my truck used and had a problem after 2 races-then replaced the geard and shimmed them according to this process and now have 4 gallons and counting on the diffs.
Other than that just watch out for the fuel tank if your track has extremely large jumps or you have a few extremely rough landings. The STRR is a dream to drive.

Does anyone make a hopupped up Hub carrier for this truck? What about arms?
I took my truck out for the first time and found out the hard way that the guys saying this truck is brittle were correct
First time I broke both the right front hub carrier and arm. (What is the easiest way to change arms, very difficult to get that inner hinge pin out and put eclip back on). Second wreck was the truck doing endos and broke the right front hub carrier again and both screws snapped the conned the steering rods to the steering plate. I was using Tony's screws.
I liked the way the truck drove, but this appears to be a very expensive truck to drive. I hope someone makes hop ups for this. I'm going to try to boil the parts next time, if they still snap like twigs then I'll stick with my Losi. It doesn't drive as good, but I've yet to break a part on it with MUCH harder crashes.

Yeah it must be intermittent with parts breaking. I’ve had my ST-RR for about 5 months now and I’ve only broke one suspension arm. But that was user error, I clipped the wall after the back straight at Revelation. It was a solid hit, so a broken suspension arm was understandable. Other then that, the thing has been solid!

Take the front bumper off, then slide the arm off the front.
You broke the screws on the steering rack? That must have been some serious hits! I've driven my ST-R for over a year and haven't broken a front arm. This has to be the toughest truck I've seen on the track. Maybe it's because you are going so much faster with the Kyosho so it's putting more energy into the crashes...

8-hole pistons are more of a buggy thing. I ran them at the Nitro challenge on the truck and while they felt good, i just don't think they had enough "pack" for the truggy. Now if the track didn't have a whole lot of big jumps and was very rough / had a nice choppy rythm secton then I think they would be dialed! ;-)

Yes, both screws. But that crash was simply clipping a tube with the left front that sent the truck doing cartwheels down the straight
I do race on hard packed clay indoors, so the surface is much harder than outdoor tracks.
Also I bought the stiffer servo saver spring and have it cranked all the way down, wonder if that caused the problem?
Either way, I'm going to try and make this truck work for me. I turns so nice

Also for reference you can't compare one crash to another. Who's to say the the endo's the truck was doing weren't more violent then any other time. All it takes is hitting something at the right ...welll, wrong angle and any vehicle can break.
