Last outdoor season I was using blue rollbar front and yellow rear in general. Springs were Tamiya blue or Associated silver front and rear. Only at one race (German Champs) I was using yellow rollbar front and no rear with yellow springs front and rear.

Spent some hours on exactly this meself, last night.

First work out *what* is binding.

Is it your bevel pinion? Turn the shaft by hand... if it clicks once every revolution then its the pinion - It will be at the same spot all the time. Note where the rough spot is.

If it jams once every 2.6 turns, its the spur.

Then open up the gearbox carefully, don't pull the gears out yet. Look inside and take note of which teeth are touching between the 2 gears & mark them. Take out the gears and inspect their teeth around the touch point, you may have to clean out any molding excess etc.

If your centre shaft has been dropped on a hard floor before... you could have dented the tip also.

Sometimes just over-tightening the gearbox cover's 3 screws is enough to cause binding. Back them out a half-turn and try again.

Each car needs its own individual finessing, but it does work.

What were the conditions that got you down to yellow springs and yellow front swaybar only? Was it rain?

yes it is the bevel gear binding and it doesen't matter how many gears you put in its still there, i've also tried different shafts and still nothing.
I think the problem is the bevel gear is slightly made badly and it is of centre and i was wondering if anyone knew how to solve this

Not sure if you meant if you tried a new bevel gear. If not, I will try that first. If you did that already, maybe your bearing is broken or not fitted correctly inside the gear case.

Have you tried using one of the bevel gears with the back cut off? It was part of the fix for helping with the mesh on the 1-way to keep it from stipping.

That is a terrible idea. It would weaken your bevel gear and make it wobble.

How to get rid of some binding

One of the reasons why the people using the Tech Shaft have very smooth and "bind-free" drivetrain is that it requires the use of an extra bearing in the front plastic upright that the shaft goes through. Using the same idea, just buy a bearing the same size as the one that goes in the motor mount, put a thin layer of CA on the edge and stick it in the plastic upright. I have done this and there is no high spot anymore when using the standard shaft and it is as free as when I used the tech shaft

Never had to race in the wet since I have the EVO3.

No it was a very large track with a high speed sweeper and I needed more overall grip there for being fast. Tires were limited to one Spec tire so I had to change setup according to track conditions.

i just sold my tech racing 3 piece, just thought it was too heavy and if u inspect very carefully u will find there is the slightest binding actually there, i think its covered up a bit becasue of the weight of the thing.
I think im gonna put the front bearing back in though.... but it means getting rid of my shiny red one

Thanks
