working fine.  I had to replace the mounting plate seal awhile back; and =
I
notice now I have a very slight leakage from the prop shaft seal - like
maybe a few drops an hour.  Otherwise no issues.

Hi All,

   Over on the COZY list, there has been some discussion centered around =

one flyer's most recent problem with his "PSRU".  A question came up as=20
to whether any of the reduction drives are actually operating=20
(relatively) trouble free.  It got no particular response.  Seems like=20
there are a lot more RVs flying with "auto-based" engines requiring=20
gearing down, and I've only heard of one rotary engine that didn't use a =

reduction drive.  Soooooo ...

How many folks here are flying with a RWS RD-nx?
What sort of troubles (if any) have you had with it?=20
How many hours flown since the last incident requiring maintenance?

I'd like to share the information I obtain with the COZY group, but only =

in the aggregate - no names (unless someone volunteers as a reference).

Also, as a COZY builder, I'd feel kind of silly joining an RV list just=20
to ask the questions. Is someone here that's also on an RV list where=20
alternative power is common who would post my three questions with a=20
feed directly back to me?=20

Thanks,
Dale R.
