Marian Miller (aka TankGyrl), the weight or material of the flywheel has absolutely NOTHING to do with how the clutch shoes engage! The engagement point is determined by the diameter of the clutch SPRINGS and the weight of the SHOES, and nothing else. A heavier flywheel takes more energy for the engine to spin than a lighter flywheel, and will smooth out the bottom end hit compared to the same engine with a lighter flywheel. Why would EVERY clutch manufacturer, (Ascendancy, Werks, M2C, etc), state that a heavier flywheel will smooth out the bottom end of an engine if it wasnt true? Wasnt it you who said if a person isnt a verified buyer, they should not comment on a product? Yes it was. Rather than comment on a product you have NO experience with, why dont you try a heavy flywheel and feel the difference for yourself BEFORE you comment...
no disrespect Marian, but Esteban is right. the fact that it is heaver only means that it takes longer to increase rpms and that's why its smother, just a little bit less aggressive. the only thing that determines at what rpm the clutch opens is the weight of the shoes and the springs. so the steel flywheel will open later but at the same rpm as the aluminum because it takes more power to turn steel.
Ok I hope I get this right. The difference between the two is mainly weight, the steel one is heavier and helps by giving less wheel spin and a more controllable feel off the line and through bumps and ruts. That is the theory, hope this helps :) .
Esteban I didn't say it wasn't smoother dummy , I said it opens the clutch faster , that's a fact when dealing with centrifugal force sorry if I'm a woman who knows what she's talking about !! A lighter weighed flywheel is "OBVIOUSLY" going to take more rpm to open & stay engaged smart guy .
I was talking to an engine expert and he said that the steel is superior on a buggy with a high power engine to help reduce wheel spin and add control. On a truggy he said it could go either way depending on the driver, track conditions and engine combo. I am going with it on my race buggy.
Six reviews, all rating the product 5/5 and all for the steel flywheel and collet variant for the Losi 8IGHT and 8IGHT-T. Reviewers largely agree that the steel flywheel's extra weight smooths engine bottom-end response and reduces wheel spin, improving control off the line and over bumps and ruts. They disagree on whether flywheel weight affects the rpm at which the clutch engages; some say only shoe and spring weight determine engagement, while others say a heavier flywheel changes how quickly the clutch opens. One reviewer notes the benefit may depend on the vehicle, engine and track conditions, and recommends steel more firmly for buggies with high-power engines than for truggies. The reviews contain no notes on durability, fit or installation problems.
