shock shafts?
What are the shock shafts made out of, I am assuming steel? Do they make ones of a differant material (IE: Titanium). That may help if you can switch shaft material type.
Looking at that jump, your going to need something STRONG!! But then again, iif you beef up the shaft, then what else may break? Worth a try I guess.

Cain, I snipped this from the cen forums for ya.
Now how you would measure them could be a challenge! I guess buy some tiny drill bits.
To check if you have the old pistons just check out the size of the holes in the pistons, the old #1's had a hole that was only about a 1mm in diameter. And the #2 was only a litttle bit bigger and the same for the #3.
The new #1's are 1.5mm in diameter I believe (maybe 1.75mm) Sorry I can't remember the exact size of the new pistons but there is an obvious size difference when you put the same number old piston to the new ones.

Cain,
I would suggest you try and find a set of round feeler gauges at an auto parts store that are normally used to measure the spark plug gap on cars etc.
From memory (not been a auto mechanic for awhile now!) there should be the right diameter gauges on something like this.
I wil post a picture of one if required, would just have to find it on the net!
Pretty sure snap on used to make a set...
Hope that helps. It would be alot easier and far more accurate measuring it this way rather than with calipers, particularly at that size.

lol.. well arent you just a wealth of knowledge! lol.. your formula i so wrong its just silly dude... factor in 30+mph at a forward angle next time!
i broke 2 shafts the first day out, period!! i dont care about your fancy quantum physics, they only work in your dimension..
is that clear?but since some people around here seems to think its virtually impossible for me to have broken a shock shaft, i just so happen to have recorded the first time out with my matrix!! i was by myself at the track, so i just had the camera sitting.. but i did record the breakage, even took pics before i moved the truck! i forgot about this vid...
before i hear "your bein too rough on it" just know weve been running on this track for a looong time, we built it!
its private...ive never broken a shock shaft out there on any other rc ive had. i was running a jammin last. weve got a bunch of brands that run out there.. many sportwerks buggies and truz, hyper 7 and 8s, a few losi 8s, too many jammins, a tazer, k cars, revos, maxxs, savages, some stadium trucks, even a baja.. and now my matrix, which by the way is ruling to loop!!
i cant remember the last time someone broke a shock shaft on the jumps.... i broke 2 the first day out?
in this vid i come up a lil short and land on the up side of the lander, but i stuck it, nose up! i would have driven away if the butt wasnt draggin.... or if i was drivin my jammin! lol..
right click and save.

ive done that exact same thing hundreds of times with other rcs and not broken a shaft..
i had it set at the long wheel base setting in the rear, i switched to the short setting and i didnt break one this weekend, still running the long shock ends. could that be it maybe?
obviously im not gonna get an answer for my question, but i just wanted to show the people who think its impossible for the shafts to break... on a jump, that it did happen!
splain that mr scientist! lol...
you didnt make it clear enough bro!the matrix rocks by the way.....
not tryin to be a jerk, but i cant stand the know it alls.. if you have an answer to someones question ya dont have to be rude about it! but in your case you didnt even have an answer, i just received the rude part? lol.. but i noticed in other threads robert hull get on peoples nerves, so im just pokin at the grouchy dude!
hope you can take a lil sarcasm?
ill stop now...
booya!!

think about the geometry in the shocks if the truck lands on all 4s no matter how hard the shaft wont been cause it will be going straight in but its hard on the truck or buggy

I broke a left rear arm on my Matrix the 1st tank of fuel on a track back in Jan of 2006. I have never broke a rear arm since. People usually have bad luck when they first get a new car. But if the same thing keeps breaking, then there is a problem imo.
Any part on any car can break, but most do not or rarely ever do.

I have not seen the new diffs, but the new plastic case is different, so you don't need any washers behind the gears.
If you want to keep using the alum cases or the old cases, then you need my cross pins.

Hey guys,
Got to run my matrix some more in track conditions, but had issues with the clutch I think. Matrix of course was the bomb!
Basically, the clutch locked up so the whole drivetrain would spin. Thing is, I check it before when it did this and the bearings and all were super smooth.
I am thinking of just replacing the bearings as I did put new stuff in for springs last time.
Loads of pinch on my OS VG .21 still, had to loosen the glow plug to get it to fire!
If I can just correct this clutch issue, I think I will be all set.
By the way, if the engine won't fire initially till you blimp the throttle some, but then runs fine pretty much, what do I need to adjust?

Engine Break-in
Should I be making adjusments to the engine during the first three tanks? I have not made any. Getting the car to idle for more then 45 seconds. I am assuming this is normal but I figured I would ask. Three tanks is going to take a long time at this pace. I have only run about half a tank through.
