Hi, i want some help for the High Dynamic centax.
From what I have read so far is that the correct way to build the HD centax is the same as the standard (0.6-0.7mm gap and 1.0-1.1mm preload).
When I try to build it that way the clutch slips and the car does not start.
After experimenting I have found that the only way that the HD centax operates properly is when I build it with 0.6-0.7mm gap and 0.0-0.3mm preload.
This way is operates properly. My problem is that the clutch works properly for the first 5-10min of a race and then the preformance starts to degrade.
Could you enlighten me on this?
Like Drew says...
0.4-0.5mm gap
I always start with around 0.75mm preload and adjust until the clutch starts slipping. Then I back out 1/4th of a full turn and that should be the spot.
I also use the small set screws in the shoe and have found that this produces a more aggressive clutch. Also, the red shoe is a great improvement over the white or yellow.
You should also take a look at the XRAY hard spring for the clutch. I have had trouble helping others with their clutches and always have found the problem to be in the spring being too soft.
Check these springs:
-RCAmerica Spring
-Xray HARD Spring
-Shepherd VCC Spring
-Mugen MSR Hard Spring
All of them are very good springs. Careful with the MSR spring, a friend of mine bought one recently and found it was too long to fit the clutch... But I believe this was just a bad batch or something went wrong with it.
