Yes, you can use metalic brake pads but I don't think it will fit ( I guess they are too thick so keep it original or buy the yellow pads ).

My turn to ask question : anyone have problem mounting the brake disc from mtx3 prospec into mtx4 ?

I have discover 2 problems : 1. the brake disc actually hit the bottom of the upper plate ( I had to dremel the plate to remove some material ). 2. The brake disc touch the carburator
i found the same problem with the tz os carby so i turned the carby away a little just enough to clear and adjusted the carb ball end around so it doesn't rub anyware andd didnt have to grind anything of the carb
looks like the prevois owner did mod the upper plate though
thanks asw for the tip
cheers
joe

On an other topic.

As mentioned earlier, I have fitted my mtx-3 prosepec brake disc to my mtx-4
with out any probs using an rb v12 now I changed to JP x-12
disc rubs on the carby, I guess I will dremel carby.

Interesting to hear other peoples comments.
Same thing happened to me. I used a sandpaper coz it rubs just a little bit. Using a dremel might over do it...just a suggestion

Sorry, this was a chart that someone posted sometime ago but only with Mugen shocks. Dk blue springs would fit between sky blue and white springs if im not mistaken.

Hey, what that brown file Rasps thing that everybody uses to file their foam tires after using the tire truer call? I'm trying to find one. By the way, I just finished running the Texas Biggie and did not have any problems in Tech with the MTX-4 fuel tank. But I did have more rear tire wear than the front tires. I'm running about 2 split and by the time I'm finished, the rear tires are smaller than the front. What would cause that? I'm running 30,000 oil in the rear so I think I should go back to 10,000.

I want one of those files also. I think they can be found at some craft stores but as yet I haven't seen them....aahhhhhh.......well not that I go into many craft stores!!

For 30+ minutes races I usually run more than 2 mm split. Something like 3.5. And actually the car feels pretty good at the start that way.

I think you're talking about the carbide file from Mico. I got mine at www.ashfordhobby.com give Robert a ring.

couple questions?

which sidebelt pulley makes front and rear drive ratio the same?

also, how do you adjust width using pivot balls to get standard setting equal on both sides?

thanks.

25t sidebelt pulley gives the same drive ratio.

I use a caliper to measure the width settings to get the left and right equal.

during Asian finals,we M'sian team did sitdown with Kenji and start to raise few problems and comments on the MTX4 kit.

1)Chasis ez flex : they already noticed and sorry coz they cant see in during design drawing,other than the option 4mm LCG chasis,they wil try to get the 3mm better material or such like that.

2)Clutch bearing damages : well we have to take the +&- or pro&cons about it coz smaller bearing rotates faster,you will have to maintain it and regular swap for heats and finals.Anyway,they will see if they can find better material for it.You can also try the rubber seal bearing.

3)Rear swaybar error: as he said,really cant see during the drawing stage but Japs drivers got no complaints about its touching the 2nd gear housing especially when you are tuning the car on the staterbox or holding it.But during the car is on the ground,it should be any problem,I did mentioned it is not good for good quality image..sales talk..

4)Tank capacity: I showed mine in M'sia we measured it is 77cc,i end up putting like tank insert and shorter line and manage to get it 74.5cc.He knows about tank problem but they solved it already and he will check again the matter.We took my car and he himself do the checking but end up 73cc.He said maybe our checking gadgets not accurate and ask me to take out the insert as in some Regulation,no insert or anythg else should be inside the tank.And i loose fuel timing too..

5)2nd gear housing bearing : they are improving that part as they bumps into it also,the bearing keeps coming out.

1)ok, but flex is very good at low bite tracks....
2)ok
3)just needs better quality control since some cars have clearance between the bar and the 2nd gear hounsing and some not.......
4)NO WAY AT ALL.......our measuring instrument is extremely accurate and ALL mtx-4's weren't approved while every 1/10 200mm car from other brands were easily approved
5)ok

just to add a comment about rules.......

you can use the insert inside the tank as long as it fixed...........loose inserts aren't allowed and the reason is obvious........
