After cleaning everything I put on a new shoe and tried again. Once again, the top of the shoe was shreaded to dust making it too small to be used as a clutch shoe.

I have never seen this behaviour with any centax clutch.

Being a 120km from the nearest hobby shop, and only having one shoe left, I swapped out both the clutch bell and went back to the old flyweights. Car working just great now but I want to use the new weights.

Can anyone guess why the shoe would get all grinded up. I've never had a defective clutch bell before and I can't see how the flyweight could cause the problem.

Thanks in advance for any suggestions.

I have seen this happen one other time. However, in this case it was a change from the standard clutch bell to the light weight clutch bell that caused the problem.

I use the new 903199 flyweights in my clutch and I have not had any problems with them. I like them better than the standard weights.

Lee/Pyramid:

Some questions?

1) Are the weights weighted (i.e. with grub screw) or not (i.e. without grub screw)

2) Are the flyweights on pins or between pins?

3) Which spring? 1.7, 1.8 or 10mm 1.8?

4) How much tension on the clutch spring? 1.0mm 1.1, 1.2, 1.3?

5) Clutch gap? 0.4, 0.5 , 0.6, 0.7?

Thanks.

going4#1, I had the same problem...
But atleast, I stopped before I completely melted the clutchshoe (training)

My experience is also that the flyweights are a bit lighter then the standard ones, so even if your clutch engages at the correct RPM, the flyweights don't have enough power, so your clutch will slip.........

2 options here, a lighter spring, or go for the grubscrews in the flyweights...
This is what I did, problem solved (for me)

Thanks for the tip. Did you go on-pin or between-pins? I see a lot of guys going between pins and having success. Makes me wonder why Serpent doesn't recommend it.

Does anyone know if the parts will have the same numbers or will be different numbers? Will the parts be out separately soon? FD looks cool but I already have most of the parts. Be a waste to order the FD upgrade just for the plastic.

My shoes where on the pins, as I think they react more agressive then, being pushed by the pin ofcourse and not trailing the pin......
I don't spend a lot of time (money) in practice, I only race, so don't have a lot of time (money) to experiment.....
But my next experiment will be, to put another grubscrew in and place the weights between the pins, as they are shorter and they can be placed in between......

I recently got a Serpent 960/Mega ZX-21 DSII (thanks to Team Kamikaze) and I just finished putting the car together. I have very limited experience with 1/8 scale cars, but after hearing and reading comments about the car and the engine, I am sure that my decision to switch to the 960 is a good one.
My local track is at Revelation Raceway and I have seen the experts run the 960 and was impressed at how fast they can go around the track.
I know that I will never be as fast as you guys, but itís nice to know that I have a very capable car.
Any advice on setting up the car and properly shimming and tuning the engine will be highly appreciated.
Looking forward to running and meeting you guys at the track.
Thanks.

dbl, my advise:
Leave the car and engine in the stock set-up for the first couple of times you drive it, FIRST learn how to drive fast.......
