Flywheel Alum vs. Steel??
I am installing a new flywheel in my Losi 8T 2.0 and I was wondering what the advantages and/ or dis advantages are for an alum vs. steel flywheel. The steel flywheel does weigh 2x as much as the alum one. Any comments? Here are the 2 flywheels. Thanks

IMO the only advantages and disadvantages are weight and durability, the only other thing is the steel one might be a little more true and more ballanced.

Go Steel Frank.

With all the rave about lightening the out drives, drilling out the spur gear and light weight axles and hubs it just seems weird and out of date to make the fly wheel heavier. I am looking for more torque from my GRP's I dont want to take torque away? Will it do that? I don't know anyone with actual experience. Does it actually prevent flame outs? Will it decrease amount of torque on tap? What are the pros and cons you have experienced?

It WILL tame the bottom end. If you are looking for more torque the steel flywheel is the opposite of what you want. It will smooth out idle and could help prevent flame outs, but at the cost of bottom end snap. It is just like you said. all the lightened driveline parts will help spool up/snap, and the steel flywheel does the opposite. I can really only see using it on a brutal bottom end type engine, or is slick conditions.

I made one several years back but it ended up being to heavy for my likes. ( hind site I'd do new ones on a haas mill and make a little lighter) so I chucked it in the desk does any one know what this one weighs ? also how deep is the knurling on it ? & I had a problem with one of the shoe pins. when we knurled mine I didn't get real deep knurling on mine and it didn't last to long in that area. got a PN on this one? I'd like to try another one.
