Also remember that I'm not running easy removable shocks (Have full screw+nut). And that I have extra electric cables to hookup the telemetry system. Also, what engine/pipe you running? I weighed a Rossi and came out at 230g while my RB V12 was only 215g.

I see a few connecting rods breaking on that straight.

I know this subject has been treated before, but could anyone remember what page deals with 2nd shift spur gears getting stripped? First I thought this would only happen if I got sloppy with the mesh. This never happened to me with my Serpent 710 or Kyosho RRR, so I tend to think this issue is kind of critical in the MTX 4.

I am concerned now becuase that had not happened to me for so long and now I am seeing this in my car quite often, as well as to a friend of mine.

I am sure my spacing is right and the engine is very tight in place.

Will it make any difference if we use the aluminum tensioner that goes between the rear bulkhead and the radio tray? How about the 4mm chassis? Is this a chassis flex problem?

Anyone remembers any page numbers in this long post's history?? It would take too long to read through all this again.

Thanks!

gtrmx, I think that one of the known causes is the inside clutch 4x8 bearing going out and the clutch bell being allowed to kinda shift and strip the spur.

I dont think it is a chassis flex issue, but I could be wrong. It rarely happens, but sometimes it does.

Can you imagine your MTX4 run top speed 100 meter ( 328 feet ) straight ? The engine will scream to death

The only MTX4's I've seen stripping gears were caused by one of those two issues:

- Faulty mesh of the gears.
- Incorrect angle or too much angle on the engine..

Some gearings (rare, but happens... ie: 16/22 one tooth under stock gearing) the clutch bell collides with the 2nd gear bell (watch for this if someone using an aftermarket 2nd gear housing... some could be slightly thicker and touch). The remedy to this is to install the engine at a slight angle giving the clutch bell and the 2nd gear housing a little more clearance.

Watch if you have an off centered or warped clutch bell and/or housing. I've sent mine 2nd housing to being milled and balanced because was a little off-centered. They returned me a perfectly balanced housing (they tested up to 8000 rpms and their maximum run-off is 0.004 grams).

For a correct mesh, if you have some difficulties, dissasemble the 1st gear and mesh the 2nd gear first and reinstall the 1st gear one time after you meshed it perfectly.

The tail of the chassis is a little weak, but you might double check if the brace that runs from the center pod to the rear bulkhead is tightly assembled. A monoblock engine mount and/or an aluminium brace there could be of interest, but didn't found a suitable one.

Thumbs down New pinion tool from Mugen.

Yesterday, received the new pinion tool from Mugen (part no. B0532).

Doing a quick test with some of my clutch bells found that some pinions, simply doesn't fit on the holes for grabbing the pinions and unscrew them (as usual, the 1st gear ones come out easily, the tough ones are the 2nd gear). One of those cases is the 27 tooth pinion (0.8 module for MTX3), doesn't fit on any of the holes...

Is very possible that other pinions will not fit here (i'm going to try with a 22 & 23T 2nd gear pinions for MRX3/4 to see if this happens). My largest pinion now for the MTX4 is a 24T and fits on the hole... doubt if a 25T will fit on the tool. So beware and carry spare clutch bells if you plan to mess with those large pinions on the 2nd gear).

And my question is... Mugen has tried to use it with their own available pinions before launching a tool that doesn't dissasemble their own gearings?....

This is great news, I just got the same tool.
