Dale;

Tracy can tell you how many units are out there flying, but he may not know
operating hours.  I have 125 hr now on my RD1B on a 265 hp 3-rotor, and it's
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.

Subject: [FlyRotary] RWS reduction drive

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
to whether any of the reduction drives are actually operating
(relatively) trouble free.  It got no particular response.  Seems like
there are a lot more RVs flying with "auto-based" engines requiring
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?
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
to ask the questions. Is someone here that's also on an RV list where
alternative power is common who would post my three questions with a
feed directly back to me?

Thanks,
Dale R.
