Jmnay_83 - My experience with the werks clutch is not very good. I tried to run one several times and everytime it seemed to make the engine run hotter than with a standard clutch.
You must not have had it set correctly. All of our engines run the same temps. We have 6 - 8 of these clutches on our track and all of them run really well.
We run Rulon/Carbon combinations on our stuff.
Engines will overheat if you let them slip too much. That is with any clutch.
The Works clutch does rule. I have also been running a lot of the Losi clutch.
Both are very good when setup right.
I have also been impressed with the Kyosho with all carbon and 1.0 springs.
Very easy and no maintenance for a whole season. No probs with slippage either. All are on the expensive side but well worth it.
Run the Works with Rulon and find out why every onroad racer runs it as well.
