Well, from the thread back a bit about checking pitch in board from the tip 

I

decided to check mine.

72" 3 blade.

Blade one tip 17.5 deg, 580mm from centre 26.2deg

Blade two     17.7                                     26.2

Blade three   17.5                                     24.7

So I set blade 3 at 18.6 tip and 25.9 (at) 580mm. After this, to the eye 

viewing from the side when running one blade was out and in flight I'm sure 

not as smooth in flight!

So my thinking is perhaps the WarpDrive folk know something we don't. 

Anyway, tomorrow it

goes back to as was.

~j~

Set the blade by the 75% radii = 686mm from  center.

  

 It seems that one blade is off 1,5 deg, that is a  LOT

  

 Makes me wonder if they use different moulds or if  they pop them out before they have cured. it should not be more difference then  a 1/8 deg or max 1/4

 Most all that have measured there Warp blade have  unequal blades.

John,



Glad you found  similar reading to what a few of us others have found.    I 

re-adjusted mine so that all were the same at the 75% radii

point and tips were out a bit.  I never noticed it by eye but I did run it 

up and it seemed ok.  So I flew it a few hours like that and I never saw 

much of a difference but if anything it might have has a tiny bit less 

vibration and there was not much to begin with.



I have a GSC on now and if works about equal to the WARP in performance. 

And now with colder air ( 25F  this am )  takeoffs in 150 feet or less are 

the normal solo.



It would be interesting to see what difference you find with your prop at 

the new settings.  Heck maybe you might find it better than ever ?

Or maybe not.  I had to try mine to see for myself and personally  I don't 

think it makes allot of difference in my case at least.   As far as you 

thinking that visually is looks different, maybe so but hey IVO props flex 

makes me wonder about them too when on take off they bend 3 to 6 inches 

ahead.  But they seem popular and a good safety record.



Dave

Since the warp prop is being discussed. I'm curious about the mounting 

method which is not described in the documentation I have. I gather that the 

spinner mounting plate goes directly on the mounting flange followed by the 

prop hub. After that I don't know whther to use this blank flange I have or 

just washers and bolts.



I can back up the flange with self locking nuts but have not been able to 

locate 8mm cross drilled bolts. Length appears to be 70 to 80 mm although I 

have seen 80 quoted. I have the torque spec in the documents. I see warp 

actually sells mounting hardware for a very low price, is this a set of 

drilled bolts?

Dave.



The mounting plate goes on outside  of hub.



I don;'t  know if Warp recommends  drilled bolts.

I use to use drilled bolts but I don't now.  I use AN locknuts only.



I am sure some will argue about safely wire but I think it totally 

unnecessary.



As far as Bolts   -- Try Leavens in Toronto as they usually have a good 

stock of most bolts.

And if you a RAA member you get a further discount.



I have drilled many times my own heads and if you have the right length bolt 

now and are adamant that you want drilled head --  just drill them.

Yes Dave, I'll reset at the 75 percentile and see how it goes, but sure it 

was rougher after this last adjustment. Not sure if the visual tip track is 

a good indicator or not, we helicopter types are always looking at blade tip 

path…tip path plane is very important.

Wonder if the tip track is not very important for smooth operation on warp 

props and being composite, no sayng what is happening at 2500 RPM? 

Considering the lever arm at the tip, a degree variation might have a 

greater effect than pitch variation at a lower percentile.

No Dave, the plate goes on after the prop hub. I machined up a re-enforcing 

ring and drilled hub pattern rather than just use washers. ~j~

Lock nuts work ...especially if they are checked n the schedule recommended

by the prop manufacturer.  But....  You can't beat the look of a nice well

done lock wire job.  According to Ivo people don't like to cut lock wire to

check and retorque the prop bolts so they require that you not use lock wire

on their prop bolts.

AN metal stiff nuts are the go and if it's a bolt and nut situ, then lock 

wire has no place. It would be lock nuts or castle. ~j~
