Instructions stipulate to use paper between the gears for correct meshing, but it seems that you have to have the pinion and spur as tight as possible to ensure that they don't strip.

It is weird, as one ensures that the meshing is extremely tight, they bind, which could cause many other problems.

Does anyone have any experience with this?
Any help would be greatly appreciated.

Mike Here is everything I checked:
-replaced the plastic chassis brace (I replaced it with an aluminum one)
-make sure you aren't using too long of a screw in the rear chassis brace. You will think it's tight, but it may be hitting the bearing.
-make sure the motor is not moving. Again using too long of a screw will cause issues.
-replace the clutch bearings. It may be a bad bearing causing the clutch bell to move away from the spur.
-make sure there isn't too much slop in the 2-speed. It may be shifting so hard that it is causing the issue.
-I had issues with using the Kyosho TI 2-speed shaft (others have not) with it flexing. I now run the YBSlow, it is made from good quality Titanium.
-replace the rear bulkheads, the bearings that the 2-speed shaft over time can open up the plastic and have a little movement.
-I set my mesh tighter than I used to. I set it with just the 2nd gear on and just loose enough it isn't grinding (the gears will wear in) then check it again with both spurs installed. If the mesh is too tight on 1st gear i will leave one engine screw just loose enough I can pivot the engine and loosen the mesh. I also usually will remove the pipe so I'm not fighting that.

It ended up being that I needed to replace the rear bulkheads. The first time I replaced them I didn't have any new ones and got a set of "lightly" used ones from a friend (big mistake). The 2-speed shaft bearings had opened the holes just a tiny bit to allow movement.

I hope this helps. Let me know if you need other ideas, I know this was a very frustrating problem.

Hi!

IMHO there is nothing for low CG then two small o-ring ;-)
It should provide more flex then stock top deck.

In my combined Evo I cut off rear top deck mount like on pics, add some o-ring between plate and tank. Tank should NOT touch main chassis, if need more place,
just a little cut off some material from VZ211.



Regards!

I did this about 1.5 years ago when I went to a lipo battery. I lowered my tank about 2mm and if I was a bit more motivated to do a bit of grinding on the chassis I could get another few mm's.

I did this from day one so I can't compare to running the thinner rear tower. I used a glue called E6000 that comes in a tube. It is available in the USA at Home Depot. I put the glue on and then used a vice to hold them together while the glue dried overnight.

Here comes the dremel

I have a LiPo ready for operation which i guess its lighter, by the way would it really aid the few mm, thinking about it it should as the tank filled up is quite heavy.

Will check it out

So the KM is needed just to be able to fit an XRay tank ?? What so special about Xray tanks ???

Copper is quite soft, but brass is a much stronger metal as well as much higher in resistance to corrosion.
