Lightweight Flywheel

[rs4evo]

*EDIT* i appologize, i asked if this flywheel would fit and forgot to tell ya'll what flywheel i was talking about...brain fart...sorry. here it is http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXTG76&P=7

i was wondering if this flywheel would fit on my RS4 3evo with rotostart? what is the difference in a pull-start vs. non-pullstart flywheel? will there be much advantage to the lightweight flywheel? i know on 1:1 cars this is a good idea because it reduces rotating mass. sorry for all the quesetions.


on a side note, rather than making another thread, i was at a LHS that i saw the other day and decided to check it out for i needed some glow plugs. the guy thought i was nuts for even thinking of putting a novarossi in a RS4. i would like to maybe do this, after i have had a lot more experience in nitro r/c. or AM i crazy? i would beef up all the drivetrain first of course as well. practical or not..is it doable?

pull vs non pull start I would have to assume that the pullstart one would be smaller and lighter... It would be smaller becasue it is start with the roto start(pullstart) with a non pullstart motor it is started with a bump box and the fly wheel is a little bigger so the wheel of the box can touch it.
With a light flywheel you would be quicker off the line and faster over all( I think) but it would be harder to tune the motor... the sweet spot is a lot smaller.

Actually, pullstart flywheels are usually larger in diameter. The reason being is that the engine sits higher on the pullstart engine mounts, to make clearance for the pullstart housing.

Both pullstart and nonpullstart flywheels ride close to the same exact clearance to the bottom of the chassis. The pullstart flywheel is just thinner.

They are also the same mass, roughly. Just different shape.

This is the case with the RC10GT; I'm sure it applies to this car as well. If your LHS has both PS and nonPS flywheels in stock, hold each up together, and compare.
