search helipro' south under discontinued engines...and a cross check of the OS parts listing will give you a second source as well...they are not unique to the sf/rf series engines

Does that engine have a collet type drive washer? If so any engine that has the same dia. shaft where the collet rides is a compatable donor. An example of this is that I once needed one for a Rossi .45 and found that the one off a Saito .82 fit because they both had an 8mm shaft.

Either one of these should work for an OS 61 RF rear exhaust.

This is the replacement drive washer for the following OS engines:
.61 SFN-H w/6B carb .61 SFN-H ABC w/6B
.61SF .61 SX-H Heli SE
.61 RX-H Heli RE.61 RFN-H RC
.61 RFN-H ABC RC.61 RF
The 61SF or 61RFrequiresthis thrust Washer http://www3.towerhobbies.com/cgi-bin...?&I=LXCW52&P=7 Also works on any of the above engines.
It will also work on OS 61FSR and OS 61VF's sometimeswithoutthe addition of the Thrust Washer.
All these engines use a 5/16 prop nut. From .61 to theFT120/160 http://www3.towerhobbies.com/cgi-bin...?&I=LXCT59&P=M
