Barry,
The 86-91 FC housing is deeper than Bulent's Cosmo housing. The
FC housing places the prop flange 4.550" farther back than Tracy's
standard mount plate with the adapter plate I had machined. The
total distance from the engine rear surface is 4.550+3.550=8.100".
To this you must add the length of the RD1 gear housing (I do not
have it here). Off the top of my head I think it is about 11.5"
which is 8.100+11.500=19.600"+or- total distance from engine rear
housing surface. FWIW

Re: [FlyRotary] Re: RD1C to FC Housing
Hi Barry, I know that the distance from the engine block (where the bellhousing meets the engine) to the mating surface with Tracy’s RD is 7” on my installation. This is about 3” farther from Tracy’s standard mount. We also benefit from having smaller cheek cowls and have less disturbed air going into the prop.

Bulent,
The Cozy- Lycoming crowd has always been buying Judy Saber's 8" prop extension to push the prop out as far as possible from the wake of the main wing. While I understand that it's hard to generalize because the engine mount style makes a big difference, have you made any calculations about how far back the prop is pushed if you mount the RD1C on the 86-88 tranny housing? Is it roughly equivalent to the typical Lycoming O-360 on the dynafocal mount with the 8" extension?
