Can some one please clarify the purpose of wanting a lighter or heaver flywheel. What aspect of performance does this affect. Just wondering, thanks.
 
There are many differences. One of the first things you will find is quicker acceleration of the engine. There is less weight for the engine to get spinning. Your engine will be more responsive to changes in RPM.

Is this good? Depends on your situation. It is used to help tune for the track and driving style.
 
one thing eddy failed to mention, is that in a bashing format, a heavier flywheel is usually better. The heavier flywheels allow for less loping in the engine, and create a much smoother idle. this isnt a concern in racing, so the lighter the better for increased acceleration.

Keep in mind, however, that the differences between the heaviest and lightest flywheels will still be very minimal.
 
Thanks guys, that clears thing up a bit, I do more bashing so I think I may get the Heavy one. Are flywheels a difficult thing to change?

no, not at all. However - DO NOT replace the flywheel just because u can. You will be wasting money and time, and will notice a very small, if any, performance difference.
 
Remove your engine, clutch bell, bearings, clutch in that order then there will be a nut, separate or connected to the shaft depending on the setup you have. Hold the flywheel with a channel lock or a flywheel tool and remove the nut. There will be a cone shaped washer and possibly a spacer behind the fly wheel.

Put everything back on in the order it came off. Make sure the nut is tight.

You may want to carefully lay everything in order the way you took it off.
 
That sounded frighteningly enough like an invitation to something better saved for the bedroom...where you two can have some privacy.
 
i agree with maxx. anyway so since I'm hopping up my rs4 3 ss for racing getting a lightened flywheel is a good idea? along with the very f-ing expensive break aluminum breaking system? thanks

Yeah Sky they're freaking me out man...hehe.

Nitroaddict is correct and IMHO in most RC applications I would go with a stock or heavier flywheel.

In REAL cars lots of people make the mistake of adding a very-light flyhweel to their tuned cars. YES your cars revs allot faster but the revs drop just as fast. In most real car applicatoins a "lightened" flywheel will help but not a s super lightweight one.

I'm not sure how this applies to RC motors as I've never gone with a super-light flywheel but I probably wouldn't want one.

Peace
 
did nitroaddict get banned? I'm gettin a lightened for racing

damon
 
yes he did but it may just be temporarily look for the thread that explains in the search
 
Yeah Nitro got temporarily banned for suppsedly making a racist remark......although the manegment doesn't believe he's a "racist"...lol.

Peace
 
Rotational weight. Round things get heavier as it spins.
A heavy flywheel will have more rotational force behind it to help the engine when going up hill and the engine has to actually work. Or going through grass.
Light flywheel has less rotating mass better suited for smooth tracks that have short straight aways.
