What droop settings are you guys using? Do you have to change droop as tires wear?

from 1front/4rear to 2front/6rear (from bumpy/tight track to wide/high bite track)...................

I don't use to change downstops to a 5min qualify and a 30~45min main final.........

Yes, ideally you need to adjust your droop ( downstop ) to match the foam thickness. However, in reality most people set and forget it.

There are some downstop combinations depending track condition and driving preference:

2 Front 5 Rear ---> most stable ( good for high traction )
1 Front 5 Rear
1 Front 4 Rear
0 Front 4 Rear ---> most responsive ( good for slippery )

nop....the lower the number you measure the higher is the droop setting......droop is the negative travel of the suspension, so more droop is good for low bite or tight tracks because you get more off throttle steering and less on throttle steering.......

Default Uneven spur gear wear?

I have not had any problems with my 2nd gear, but I noticed my first gear(59) has been interfering with the lower suspension arm to the point that it ground a small groove into the arm. The spur looked like a 45 degree cut along the outside edge of the gear from the contact of the arm. I think the pinion is now uneven because I replaced spur (58) and it ground same 45 in new smaller spur. Rear lower arms feel a little sloppy on the pins? anybody heard of this?

Thank You

Is it the inside or outside of the gear that is getting worn down?

I just had this same problem. I think you will find that if you take off that rear arm you will discover one of the following. A broken rear arm at the rear pin location or the the lower pin is bent. In my case the lower arm was broken where the pin goes through and allowed the arm to move forward and hit the spur but enough to really be that noticable or come completly off.

Oops I just re-read my post and I missed a word.

Here are the parts that can be transfer to build MTX4 clutch from MTX3 ( I build it recently ) :

Flywheel
Clutch Shoes : 4 pieces + 1 round
Centax Disc : Metal
Spring
Flywheel Locknut

That's it.

You need to add MTX4 original parts such as three small bearings, Spring Locknut Adjuster, Clutchbell, and pinions 17/23 or 18/24.

Yes, you can put the whole MTX3 clutch system directly to MTX4. However I don't recommend it unless your home track has very long straight like 120 meter plus.

No more gear stripping when using mtx3 gears ? I don't know.
