Hi,
A manifold pressure gauge is a mandatory LAA requirement - you may as well
use the one supplied by Smart Avionics. Can't see the advantage of using
anything else.
It's pretty likely that a 2 bladed prop would be unacceptable to the LAA due
to the increased diameter. The standard 3 blade prop is just on the limits
of what they will accept for a mono-wheel (especially the original Classic
engine installation). The newer engine mounting/ cowlings have the engine
about 2" higher off the ground than the original design.
Hope that helps,
Carl

Subject: Europa-List: Re: Propellers - Woodcomp SR3000/2W
Frans and David,
Thank you for responding to my general query on the Woodcomp propellers in
the MP thread. I'm responding in this one as it seems more appropriate here.
David, I read with interest you article in last years Europa Flyer regarding
the higher twist performance of the SR3000. I assumed that Woodcomp had made
this especially for you and wasn't readily available. I imagine the LAA will
now accept this prop on the mono. I suppose one complication may be that I
have the 912S engine?.
Fran, Like David I have the monowheel and although the two blade version
would be attractive, would the smaller blade performance be acceptable in
the two blade version. If this option were chosen I imagine the LAA would
require extensive testing to be carried out as well. It could be an
expensive experiment.
So, I will get a quote for the SR3000/3W 1650mm complete with backplate and
spinner. David has done all the hard work in getting this accepted by the
LAA. All that I have read would suggest that the Smart Avionics controller
is well suited for the job. Would either of you recommend their Manifold
Pressure transducer or did you go for something else.
