Default O.S. .18 CV-R flywheel???

Ok asking this for my brother-in-law who got a O.S. .18 CV-R engine for his HPI MT-2 for X-mas. He got the motor mounts from HPI and a nice exhaust but it seems the shaft on the new engine where on a normal engine the brass collet goes, the new OS has 2 flat sides on the shaft that a big spacer with groves sits over it locking it in place. The flywheel is supposed to butt against it and then be tightened down but if ya take that off and try to stick the brass collet ont he shaft and then the origional flywheel on, no matter how hard you tighten it it slips when the piston get to TDC (guessing the collet slides on the flat side of the shaft). So I need to know what kind of Flywheel/clutch can he get to use the little flyweel spacer thing that came with the engine? Will an 1/8 setup work? I know the back on them is pretty flat like the CRT one I have on my Mayhem ST, or will a 1/8th setup not for on a .18??? So confused any help would be great!!!
