Except for the colour, this is the difference.

This is MS(I believe for all chassis except AR and MA ) basic tune.

1 pair 13 roller.
2 pair 19 roller.
2 pcs of bowl mass damper. (same with AR)
Pair of FRPs.

This is AR basic tune.

All 13mm roller.
2 pcs of bowl mass damper. (Same with MS)
Pair of FRPs.(Same with MA)

This is MA basic tune.

All 13mm roller. (same with Ar)
2 pair of adjust mass damper.
Pair of FRPs.(Same with AR)

Official tips u mean this pamphlet?http://www.tamiya.com/english/mini4wd/pdf/ma_1.pdf
That pamphlet suggesting the AR basic tune set for MA chassis is released(maybe last year?) before the Basic tune for MA is release(which is release this year).

And look closely at the damper .

EEEEEEEE!!!!!!
jom men tamiya ngan kuda pink :3

I already PMed asyraf. Still pending his reply.

My car also has similar problem with u, jimmylim85. My car did not landed properly, not overshoot. I suspect the braking is not good enough. Any other thought guys? My damper is very minimal. I only use the basic tune damper. (2 pemberat at front)
Chasis super 2. Roller 6. (front 11mm ball bearing, rear 13mm guided ball bearing)

if the rear rollers get stuck , adding one frp to the bottom will help prevent it ...
