im guessing this is what your supposed to use..but can i use my old one?(was on a os.15cv-rx)? I put the old one on...it should be fine...but im not totally sure.

if u want an unstable idle and insane spoolup use the small block flywheel but its too light for a .26 use the .26 flywheel

the new flywheel looks small...it seems to be the same weight..ill put it on a scale later

That thing you linked to is not a flywheel. It is used to mount a propeller or certain types of flywheel to your engine. If your flywheel uses a collet to mount it then you don't need that thing.
