Lightweight flywheels and spur gears have their ups and downs, it really depends on the terrain you are running on.
The up to a lightweight, is that you will be able to spin up to full speed much quicker than normal, since there is not as much weight for the motor to push.
Yet at the same time, there is also going to be a reduction in torque.
Now granted I do not have the expierence with this in RC cars, but the above stands true for real cars. I would assume that logically the same would stand for nitro RC as well.
I think it would really just depend on the application.
Yeah I understand their benefits on real cars, though I know a drop in torque production at the wheels doesn't make sense. I know that with real cars (specifically manual transmission'd ones), a lighter flywheel means it is more likely to stall during takeoff. In that same light, I just wondered if the reduction in rotational inertia would make it die much easier when it would otherwise already be close to dying (when starting up, if the engine loads up).
But, I think I might try it out! At the very least Ill lighten a stock flywheel.
