Ok, this is the last question hopefully!

Do I have to disassemble gearbox to adjust the diff?

Thanks

No and you can get the instructions at http://www.teamassociated.com/ look it up in the manuel, its pretty simple [&o]

In the manual is says "Its not meant to be a tuning option" but I read in the other forums that you can set your diff depending on track surface.

Does Lock or fully tight diff will cause you to strip gears?

The dif can be used as a tuning option, but it is not recomened. Its sole purpose is to allow the outside wheel to turn faster than the inside wheel during cornering.

You diff should not have any slip in it at all. I usually run my diff on the tight side. Tighten the adjustment screw till the diff spring is compressed then losen 1/8-1/4 of a turn. An excessively lose diff will do nothing for performance and just wear out parts sooner. Don't confuse a smooth diff and a loose diff. If built propery, your diff action can be very smooth with the proper "tightness"

If you are running an a low traction surface, it is better to losen the slipper. That is what it is there for.

Good luck.

Unless you are drag racing, there is no need to fully lock your diff. If you need to do so, build the diff without the diff rings and balls, but I wouldn't recomend it. You are not gaining any acceration by locking the diff.

On overly tight diff by itself will not strip gears, but combined with an improperly set slipper (too tight) and hard landings with the throttlle pinned could strip gears.

Thanks...I did read through the manual but looks like there is no short-cut to adjust the diff. It's because it is new and just ran 4 tanks so diff needs to be checked over, re-tightened if needed.

Correct me if I'm wrong, isn't it possible to adjust the diff using the rear wheels while holding the spur gear? I read GT2 RTR review, a reviewer found the diff was a bit loose after few tanks so he re-tightened it!

Right, you had to disassemble the rear truck to check the diff? Thanks

No,

You do not need to disassemble the gearbox to adjust the diff. You will have to remove the camber tie rod, to remove the cva. You can then access the diff adjusmtnet. I only adjust the diff when it feels to be getting to lose.
good luck

Thanks, just what I wanted to find. Manual doesn't mention anything about checking the diff or accessing to it!

Cheers

take the rear dogbone out, and stick a screw driver in the little hole in the gear box (the thing the dogbone sticks into) (forgot which side it's on), tighten the screw all the way down then back off about 1/3 or so turns...in answer to your question no you don't need to disassemble the gearbox, and yes it is a very helpful tuning option...also make sure you have some good grease, or lubricant so your diff is smooth...

too tight- wheelies, bad cornering, will spin out easier

too loose- slower through turns but more forgiving b/c you won't spin out

One of my xtreme rc magazine articles had everytihng about the diff in it...check out rc411.com
