Tony,
The pressure transducer is for the stall warner of course. However,
there is a problem with this install with the adjustment and
maintenance. It appears he has a tube for adjustment of the sensor from
below the panel, but Redux permanently mounts the sensor. I sure hope
it never fails. Getting a cutter in that area means pull the panel and
cut Redux. I also noticed his com jacks under the floor of the shelf.
Again, not easy to service and a bit of a hunt to find.
I prefer the stall warner in the wing next to the tube passing through
the spar. I mount it on a couple of bolts through the ply and run the
wires to the cockpit. Tubing is harder to run through a conduit than
wire. However, the easiest to ajust was put into the cockpit module
just forward of the rudder pulleys with a hole to adjust. Makes it easy
and fast for flight test adjustments in flight.
I normally put my com jacks in the upper aft area of the above head
console. If you want them in the panel, we have installed the pilot
jacks on the far left panel bottom and have made a simple foam shaped
piece for plugging into the pax sides for direct plug in of your
headsets. With it on the panel, the inspector may want it labeled but
that is only in a few examples.
Regards,
Bud Yerly

Hi Jos,
I have been reviewing pictures on the EuropaOwners website for my
instrument panel, for ideas, and came upon this photo. Can I please ask
what it is??
It appears to be a pressure sensor, a pneumatic pressure sensor. Is
that right??
Regards

The good news is, that this will be my last contribution to the
list. After this message i will unsuscribe, and withdraw from the Europa
community. I will not go again through the horror caused by a failing
prop.
The one question remaining is which Woodcomp SR3000 was tested by
the LAA?
The following are quotes from private messages from Woodcomp owners
in no particular order.
"I think I was wrong in my guess that the pitch might have gone past
the normal fine limit as the defective switch was the back up one."
"I have heard of a Woodcomp prop stripping off some of its carbon
fibre sheathing in heavy rain, but having said that probably the
majority of the guys that I have flown with (& my own plane) have
Woodcomp props that have shown absolutely no effect. "
"but yes I have tested my mechanical stop It is strong enough to
stop a runaway electric motor I guess 100hp more powerful than the
fitted one and comes into action a degree or two past the usual position
so still capable of producing reasonable thrust"
"Jos, I thought I would bring you up to date with the prop. On
taking off
the motor I found that the drive gear that is on the end of the
motor drive
shaft was not on the shaft. Instead it was inside the hub, loose."
"Incidentally there are mechanical stops on each of my blades in the
form of a bolt which projects into a groove in the blade root. The range
is limited from 9 to 29 degrees as measured at the very tip. You can see
---From the picture of mine (with the loose bolts) and an earlier factory
one, that they have not always had this feature"
"On each occasion they replaced almost everything that showed any
signs of wear. Brushes, gears, micro switches, wiring etc and the blades
when returned could be mistaken for new"
"Found that one spinner screw was missing and gota complete new
spinner fastening set free of charge"
"I had two motor failures, and now always carry a spare"
"More recently like last year I mentioned a small amount of play in
my blade set, and they sent me a kit f.o.c.
for the hub. It was an upgrade consisting of different gears and
spring washers, which I installed myself and everything seems fine now."
"someone having some teeth break on the gearing that determines the
pitch angle of each blade and this was promptly dealt with by Woodcomp
replacing it both on new models and retrospectively with a slightly
heavier version of the gears"
"I had my SR3000 motor burn out which took my pitch to fully fine
and on to the stops"
"since my propeller return to service I make a point of flying it
manually if the conditions are poor"
"I am very pleased with my SR2000 approaching 300 hours. I have one
failure though"
"To avoid problems as much as possible I always switch to manual
before take-off and landing"
"Back on topic, I only had it checked once by a local dealer because
of some play of the blades"
"Forget about automatic pitch control below 1000 feet"
"I am also not convinced that Woodcomp engineering is really robust"
"We made the special propeller for David"
"Do not underestimate the speed of the woodcomp pitch motor: It will
go from fully fine to fully coarse within one second"
Regards,
Jos
