well i have my new gen-x le built and ready to go,if it stops raining 
got a couple newb questions.
the side springs can be adjusted up and down,how are these generally set tension wise,do you wind them down till they just touch or are they adjusted with more tension ?
ball diff setup
i haven't touched a ball diff in about 6 years,when holding both tyres and then trying to turn the spur with your thumb,how hard do you try and turn it ?
that may sound strange but what is hard for one person may not be for another,or should it have pressure but still be turnable
thanks for any advice

As far as the diff goes, once tightened down, it should be VERY difficult to turn while holding the wheels- but not impossible.
Hope this helps

Side Springs: Generally you want them just touching the pod so the car will self-center (In related to the rear pod), otherwise your car will be tweaked when going in a straight line. I prefer a alittle pre-load on them (1/4 turn once touching).
As for the ball diff. A properly worked in ball diff, you should not under ANY circumstances be able to slip the spur gear, but the differental action (from wheel to wheel) should be butter smooth. If you are not sure if your diff is smooth or not, then check out some of the faster guys cars. A properly working diff is super important in pan cars. If you need instructions for working in a diff, check out the link below.

thanks guys that really helped
got my first run today,had a faulty steering servo issue but other wise it ran very nice.
now i just need to up the gearing,any suggestions ?
currently at 42mm roll out with a novak gtb/13.5t on 2s
track is large out door 1/8 scale.
ran today with the 42mm roll out and after around 15 minutes of run time
motor and esc were barley warm
was thinking around 51-53mm roll out

I would not make such big jumps in gearing to get to the sweet spot. Take your time in finding the right gearing for your track. It should only take a few more test runs to get there. Enjoy the ride!

I FINALLY got my Gen-X sorted and handling damn near perfect. There was so much dust on the track I was making mini tornado's behind the car going down the dtraight, and it still handled well.
The single biggest change I made was having a super-soft tamiya centre spring. I was jsut comparing my car to my mates X-10 and the spring was wayyyy softer, so I figured I had nothing to lose.
Anyway, there were other tweaks, but my car is now a weapon on unprepped asphalt

Should be interesting this year though, looks like the club is switching to WGT rules. That will have a change of the setup for sure.

WGT rules, bummer. I had something else I cam across too. Even if I tightened the king-pin shaft all the way in, there was still some droop, which I didn't want. It was almost 1mm. Not sure if anyone else has come across this?
I ended up putting a 1mm o-ring between the upper arm and steering arm to remove the clearance. Kind of a hack-job, but works mint

On my 1/12 I have some droop, so I added a small washer to the bottom of the king pin, just above the e-clip.

I assume that you are using the 1/10th scale king pins. So, which springs are you running up front? I ran reds with no droop.

but will slowly build up more pinions for fine tuning.
tried a diffrent motor/esc today,its a sensorless system,not as smooth as the novak but not to bad.
motor is 4000kv compared to the novaks 3300kv
was much better,lot more punch and top speed is around 50mph
plus esc has much more programming options than the gtb
these cars are so much fun to drive

OK, picked up a very nice used 10 pro, but the center shock needs some TLC. Either the shock body is dented, the piston is afu, or the shock shaft is bent. The full version (NOT LE) uses a different shock, and the manual says something about following the instrucion in Bag 7. Same thing in the manual for the Battle Axe, no joy.
Anyone got a copy of that instruction sheet and a parts list?

Any advice on what oil to start with in the original and the LE upgrade shock?
Also, anyone have a good set up for a large open outdoor asphalt track 1S 13.5?
