Title: Whaty engines do these mufflers fit? O.S. 843 and 702?
Post by: frank mccune on July 09, 2015, 12:36:14 PM
    Hi All:

    I think that 702 fits the older .19 and .25 engines but have no idea as to what the 843 fits.

                                                                                                            Tia,

The O.S. web page lists 843 as just a muffler extension. Should fit an OS .35FP?

Hi Jim,

B-29 or B-50?  One of the old Kyosho kits?  I finally found my "Holy Grail" kit (that I could afford! LOL!!) a Berkeley B-17.  Now I am not so sure I will build it! LOL!!  Might scratch build a Royal B-17 instead. ;D

The picture file name says B-29, so I'd bet $ on that. I'm not usually much of a gambler, but that's one bet I'd take.  LL~ Steve

Yes, 702 fits old Max 20 and 25.
843 fits many OS 28 to 46 engines, mounting pitch 35.5mm.
