Anyone running a two blade Ivo prop on a 447. Do you run it with or without
the spacer blocks? I have a brand new prop. When I unpacked it, I could tell
by finger calibration that the blades were thinner than the spacers. I
thought they would squeeze down when the prop bolts were torqued to 200 in.
lb. per instruction sheet. Did the torque and there is still a .015/.020"
(calibrated eyeball) gap between the plates and the blades. The holes in the
blades are loose enough that the blades move, both in the plane of prop
rotation and fore and aft.
When I called Ivo, the response was, "take out the spacers, they're just for
looks". ??????
The only Ivo I have is a three blade that came on a 377 powered Minimax.
Torques up just fine. I'm torn between following instructions from Ivo and
putting them on the Bridgeport and milling them down. This aircraft is not
mine, I'm just the delivery agent, and I'm not comfortable with either of
these solutions.

if it wer mine I would Mill the spacer blocks down to match the blades

I had a 66" two blade IVO on a 447 for 600 hours with no problem and still
going

1. The prop is brand spanking new, shipped from Ivo within the last month.
2. I flycut .018 off one side of each spacer to fix it.

Please call IVO.
Something isn't right. They probably sent you the wrong block set.
I surely would not run it that way.

Rick,
This story has cured me of any chance of ever buying another IVO prop,
used to have one for the Loehle, but sold it before I had very much time
on it.
Makes me wonder if your prop blades are the right thickness.
Their attitude is ridiculous.

Richard:
I have a 2 blade on a 447...
The fact that IVO recommends (and sells) stainless steel tape pieces to
stick across between
the blade base and the spacer block in order to detect slight blade
movement in the hub (if tape breaks, the blade
has moved) is what is known in the intel business as an "indicator"....
It appears to 'ol Beauford that, based on this,
the IVO folks consider blade shifting in the hub to be a significant and
undesirable event. If I were you, I'd want
100% of that 200 in/lb. directly on the blade bases...
The rubber spacers may or may not be real players in this matter and I
have often wondered about their role....
While assembling my prop, and noting the casual way they fit against the
blade bases, it doesn't
surprise me that IVO says they are only ornamental.... just looking at
my assembly, I personally don't
see how they do much to fix the blade base into the hub with any
precision-- it looks to me like a blade
would really have to shift a lot before they would become a factor in
restraining it.
I'd be inclined to go along with IVO advice and put all of the hub
pressure (torque) on the blade bases... they
are structural...(I don't think the rubber spacers are).... and then
mebbe try some torque seal between the hub and the
blade base to see what is moving and what is not...
Worth what ye paid fer it...

Gene, As I said, "When I called Ivo, the response was, "take out the
spacers, they're just for looks"." So much for calling Ivo. :-)
Once the Minimax is sold, I'll never have to deal with them again. I did go
back and read the warning on the web site, apparently it's only applicable
to engines with 3:1 gearboxes, so I probably could have gotten away with
running without them, but now they're fixed.

Denny, The blades are pressed in mold, the spacers are cast in a mold, too.
So I doubt anything has changed, unless their plastic molding guy has let
the mold go to hell. There's no evidence of that, the parting line looks
clean, so I guess that's the way they've always been. Makes me appreciate
the Warp Drive and the Powerfin all the more.

Rick and all
Brings to mind my little bout with Ivo props... Eveyone said that a
three blade 60 inch ground adj IVO would work on my Firefly with the
447.. They were correct...A call to IVO cleared the matter up.. My blades
were labeled 10+ at the base..Meaning that they were made with a minimum
pitch below which I could not adjust for the 447.. I switched to blades
that did not have the + and all was well..
IMHO---IVO blades are good for certain applications and likely bad for
others.. I have never had a problem flying in front of them.. with and
without the filler blocks..I use a three inch spacer.. As IVO said
...the spacers are just for looks... Herb

Guys,
When transporting with wings folded, I assume you are keeping them mounted
to the universal joint at the main spar.
What about the outer end of the wing? Do you still utilize the small cross
tube that goes through the boom tube, with safety clips, to support the wing?
Seems that the weight of the wing, while traveling over bumps, would bend
that tube.

That's what I used. The fellow from whom I bought the Mk III showed me how
to make pins from a clothes hanger that had an extension handle so that I
didn't have to stretch to reach in to put them in. I've never seen any
bending of the tube, at least none that caused them to bind, or made the
cross tube loose in the boom.

I thought that the little tube through the fuselage that hold the wings would bend
also. I have trailered it 4 times now and it has not bent. One of these
days I will build a support because it does not look very strong. Vic in Sacramento

I have to go with Steve on this one, I think we have to much paperwork and carp
in this country, I could not imagine trying to operate in a place like Europe
or Britain... If it were me, the government, the CAA, or big brother would have
never known that I damaged my plane just so I would not have to jump through
so many hoops to get it back into the air. [Wink]
