Paul, I am in a similar position to yourself and indeed asked the same question
on the forum and David was most helpful in the advice he gave. However then Frans
suggested the 2W option. I didn't find Woodcomp particularly helpful I'm
afraid. I had a little correspondence with Kevin and the factory but the bottom
line seemed to be you pays your money and takes your choice.
My view is that its an awful lot of money to spend only to realize you've made
a mistake and now Graeme has concluded that he would have fitted the 'normal'
ones (by this I think he means 3000/3 no W suffix).
So I was erring towards the 3000/3W but not sure again after Graeme's comment.
One thing though the Smart Avionics Controller would be my option.

Subject: | Re: Woodcomp Prop diameter |
As you say Malcolm, I have made up my mind I'm not sure!
I know the LAA mandate a max of 1625 mm (based on clearance calcs in CS-VLA, which
is not a requirement for LAA aircraft, but that's another argument!)... they
don't insist on 3 blades - Andy Draper said they have lots of 3000/2W listed
for Sport Cruisers, but I guess they have the ground clearance to allow for
longer blades...
I suspect 3 blades may be necessary to keep a decent blade area for 1625 diameter
(with a 1650 you have more area, so can get away with 2 blades I guess).
So now it's *just* a choice of wide vs. normal:-
Data showing W is better for 914 - but does this apply equally to 912S?
or a subjective comment "If I started again I would go for the normal ones" (like
you, I think that's what he means).
Decisions, decisions!

Subject: | Torque Tube Clamp Mod. into production ... |
Dear Bob
When I asked to be put on the list for the new torque tube clamps, I didn't
realize that they are intended to solve a problem that the older torque tu
bes had. My torque tube came with kit 631, shipped in January, 2012, and I
assume from the diagrams that it is a different and non-compatable design.
please forgive the inconvenience.
Fred Tower

Hi Bob,
My torque tube seems ok at the moment, but looking to the futu
re could you put me down for a set of your clamps.

Hi! Sorry for promotional but if it helps you to know we are now setting u

Paul - for what it's worth, I have got the SR3000/3W in 1625mm diameter for my
Rotax 912S, but the two have not yet been married together, and the airframe is
a long way from completion yet, so I can't report on the success of the combination.
The high twist of the W blade seems much better suited to the speed range
of the Europa, and should not be causing negative thrust, as some lower-twist
blades can, in certain speed ranges (David Joyce has done the sums on that).

Subject: | Re: Woodcomp Prop diameter |
yes and the rationale was,
a) David J had written somewhere that the twist on his 914 hadnt given him as much
as expected (and I am on a 912S)
b) they are standard blades and cheaper, and a single blade can be replaced if
you ding one (rather than 2000 for three).
After my ding I would have gone from W to normal IF I hadn't done all the flight
testing and been through the approval process with the W.
According to Andy Draper, 1625 is max on a mono due to ground clearance and then
two short blades wont be enough.
If anyone wants two fine 3000W blades I have them - good as new.

Thanks Rowland and Graeme,
Great answers and both valid in their own right (dammit!) The choices seem to be:
W for the extra twist needed (although not necessarily as much as expected).
Normal for lower cost & lower replacement cost.
I'll get whatever you decide, MalcolmH!
Thanks to everybody for all the very useful input.
