Carl,
How old are you blades and hub? I understand the newer versions have a
mechanical stop built in so the hub cannot move the blades beyond the
"fine" setting. This all makes perfect sense to me - thrust reverse
option would scare the living hell out of me. Do I really need thrust
reverse is such a simple aircraft as the Europa?
I bought a 2 blade SR3000-2 with scimitar blades I hope to put into
service this year. I bought it disassembled and the factory provided me
with a detailed assembly manual as we in Canada live far away from
Europe and the very high associated shipment fees. I opted for the
variable pitch only because I do have an additional set of glider wings
and feathering seems to make sense. Also, the performance
characteristics of both type of aircraft require a different power/prop
pitch curve for each set of wings, that is, a fixed prop might want
adjustment every time I switch the wings - not ideal.
I have chosen 2 blade because of less resistance in gliding mode, but
also because I could save about 8 pounds weight right at the front tip
of the aircraft, not making it too nose heavy. Prop and hub come in at
8kg compared to 12 kg - a significant difference. Not much more than the
Warp fixed 3 blade! The scimitar blades look beautiful and are very well
made. I like their progressive twist towards centre compared to the Warp
as the Classic requires cooling close to the hub which will also be
positively provided by much broader blade chord in this area. I think it
is a nice combination - the top cowling also comes easily off which with
3 blades seems to be more difficult.
Why don't you ask the factory for a modification - or upgrade? I have
had good experiences with them (not with the Canadian Retailer in B.C.,
though - but this is another story!).
I am attaching the detailed manual.
Best,
Christoph Both

Help !
Does anyone amongst the UK Europa fraternity have experience in dealing
directly with the Woodcomp factory.
I have one of the older Woodcomp propellers that I was hoping to fit to
our
Europa but the PFA have decreed that it requires a factory modification
(or
a dispensation from them to do the mod myself). The reason are these
blades
are capable of going into reverse and the PFA require stops fitting that
would prevent this.
Conrad Beale was the UK agent but has recently ceased in this role. The
new
UK agent RotoSport have told me they cant help because they havent got
their
agency set up yet.
Also does anyone have a factory maintenance manual (or experience of
assembling and disassembling the hub unit) - as I need to dismantle the
hub
and am reluctant to do so without proper instructions.
My other option is to scrap the existing blades (which are brand new)
and
order a new set directly from the factory.
