So I have an OS SF that I'd like to adjust for stunt timing by installing a stunt crank (stamped SF-S). Anyone have one for sale? Also open to buying a whole motor. My Pathfinder requires two ounces of nose weight, which I am thinking might as well translate to longer lines and a heavier motor than its existing OS LA 46.

thanks,

Peter

update: Plan to use the stock crank, for now.

Mr Aero / Smith had em listed . https://stunthanger.com/smf/aero-products/

Incidently , most of the 15 mm & clone cranks interc hange,

So you could throw a thunder tiger 46 one in,for 20 mm stroke . if the flywheel clears the case , we willum check it . Hold your seats . Tomorrow all may well be revealed ! .

Theres also a 21 stroke 50 FSR crank that may well fit. Perhaps . the SF is 22 bore x 19.6 stroke, like the LA 46 .the 40 SF is the same stroke . FSR 45 crank stroke is 20 mm , ands a straight swap .
