Ouch !
It depends on which prop you are referring to ' in the last year my
Europa
has flown with four (yes four!) different props. Someone (who shall
remain
nameless) keeps ground looping the plane and has trashed 2 Woodcomp
props.
Its confusing but we put the original Warp prop on for a while so
that=92s how
I end up with a total of four. Just waiting for the insurance renewal in
October ' can=92t imagine what 2 claims for =A33,500 each will do.
We have just fitted the most recent replacement Woodcomp SR3000 prop
(the
third one) which Kevin Dilks picked up at the factory in The Checz
Republic
last week and it was balanced by them after assembly.
Regarding the balance I have one of Mark Burtons dynamic PB3 balancers
'
whenever we fit a new prop it is checked for balance and we always
manage to
get the target into the inner ring ' bullseye (which is classed as
very
good).
So sadly it aint the balance ' wish it was as simple as that.
The fact of the matter is that most modern video cameras have
stabilisation
included as standard and this deals with most vibration associated
issues.
As it=92s the norm many manufacturers don=92t mention it as a selling
point. Im
pretty sure the GoPro Hero 3 has an image stabiliser built in.
For some reason VIO didn=92t include it in their camera but I am hoping
that a
simple anti vibration mount will deal with the worst of the vibration
and
the rest can be processed out when I edit the original footage. I have
Sonys Vegas Movie studio to edit my clips and this has camera shake
software
' this helps but doesn=92t cure the problem entirely (and degrades the
quality).
It=92s something I would like to sort out in the future but not top of
my list
of priorities.

Carl, Does your prop need balancing? Regards, David Joyce, G-XSDJ
