Geoff,
We have a few recommended props depending on your mission.
For absolute speed with out robbing the engine of performance the
Sensenich WC62FK58 is perfect. Best speed and still good climb.
If you want a little better climb go with a WC62FK56.
Now the SLSA LS-1 lightnings have W60zk57G props. We get very good climb
with these and right at 120ktns for 2850rpm. This is again with no
fairings except our LSA wheel pants.
I have had guys run the W60zk57G LSA prop on non LSAs with full fairings
and still get near 130knts, but with exceptional climb, better than the
62-56.
The Carbon prop is fine, a little harsher in vibrations, the wood seems
to dampen things and give a smoother feel.
The only thing about the carbon is you won't ever get the same
performance out of it as the best cruise wood prop. This is because of
the blade stiffness, profile and diameter.
We have done lots of prop testing here, I have several that were ok but
not great and we now use them as loaners.
As with anything aviation most things are a compromise. And no one prop
will give it all.
Nick

Group,
Propellers - An old subject that still remains confusing (to me!). It
seems the 2 favourites are the 62 FK58 or 62FK56 wood propellers from
Sensenich
What are the current recommendations for the Lightning - both
Experimental and LSA. (I am building the LSA
Is anyone using the Ground Adjustable Composite from Sensenich? If so
what are your thoughts and what diameter is recommended - options seem
to be from 60 to 64 inches.
I have tried Emailing Mark and Nick but haven't received a response.
Thanks
Geoff Eather (Australia)
PS: There may be another consideration in prop selection as the LSA in
Australia is not restricted to 120 Kts

My machine is finished !! now just waiting for the Cof A paperwork before i start
my test flying.
Any suggestions and tips appreciated.
Nick, how long till the newsletter article ? If it still weeks away could I get

Thanks
