Default flywheel

Does changing the flywheel make any difference in the performance of a nitro truck. I have to change my fly wheel because my bell chewed a hole in the flywheel.

Yes, the weight of a flywheel can affect the performance. How exactly did your clutch bell chew a hole in the fly wheel???

I do know that putting to light of a fly on a nitro will prevent it from idling correctly and it will make dificult to tune as a result.

flywheel changes will affect the vehicle, but only by an ever so slight amount. You probably wont notice unless you are racing or are paying careful attention.

A heavier flywheel will allow an engine to idle more consistantly and make tuning errors on the LSN and ISS a bit less noticeable

A lighter flywheel will increase acceleration but will cause the idle to be slightly erratic and make the engine a bit more sucseptable to tuning errors.

Thanks for the replies,

I have the stock flywheel on my t maxx. It is kind of cheap looking. Should I replace it with a stocker or does anyone have some suggestions for different fly wheel.

For ease of tuning I would advise a stock or slightly lighter fly. But its really up to you and how patient you are with tuning.

A lighter flywheel will make tuning more difficult. A heavier flywheel will make it easier. You have it backwards. Although, lets not forget - the difference is very minimal.

Nitro, what I meant in that post is, If you must go aftermarket stay as close to stock weight as possible. thus slightly lighter being the catch phrase. And tuning differences will be quite extreme depending on engine. On my MT2 I had an extremely light fly on it when I bought it and I couldn't get it to idle right to save my life. It either idled so high it would overheat or it would idle so low that it would die any time i slowed the truck down. I switched back to my stock fly and it fixed all of my problems with with my idle.
