Max Pitch diff between blades?
 

Please help me out with this...

Given identical locations what is the max diff in pitch between blades when mounted in the same blade holder?

I am seeing 3* + on the new Woodies I have.

A little history:

I am relatively new. Had a boom strike the other day and put my Raptor 50
back together... Spindle mainshaft blades links boom and belt, all new.
I took it out today and started to check it out and the first thing was that the blade
tracking was way off...

What I found...

I mounted 2 separate pair of carbons on the head and the pitches from blade to blade were virtually identical. + or - < 0.5*

When I mounted the Woodies, one blade would hold at 0* while the other would be -3*.

What does everyone say? Send them back? Or adjust the head for better tracking?

Thank you...

Sounds like one of the woods may be warped a bit.... Try checking the pitch at a couple of points along it... It may also just be because of the way the root glues on... Chances are if you just track the head you'll be fine....

Checked the pitch at three points along the blades.
All consistent. Looks like bad a bad root.

I find woodies are often inconsistant. Won't fly them any more. Had too many problems with them with just what you are finding.

I am still learning and have already flown some carbons.
I have also crashed them. A little painfull at this time.
The good new is that the place I purchased them from will
send me a new pair.

Good service fom Heliproz.

TT blades are pretty cheap, good training gear help keep your blades in one piece, and not going too far too fast helps too. Can't say as any of my students have ever broken a set learning, but I don't let them just fire it up and fly around. they stick to a pretty tight regiment. Once they start getting better, they progress to the next step. If you try too much too fast, you will break them. I got lucky, never broke a set till I started looping, but that was 20 years ago long before glass blades and gyros.

There are nothing wrong with the wooden blades. I flew last season with TT 600 woods last season doing a lot of flips and rolls. They really aren't as bad as people think. Yeah carbons fly better, I agree with that, but for the price, I think that wooden blades aren't too bad for the price and performance.

Th reason for the broken set of blades is simple.
The brass sleeve on the tail slider separated. Threads and sleeve were
left inside the yoke and the rest of the sleeve was separate and thus
no tail rudder control. Happened and I came down a little hard on landing
Boom strike...

Simple as that...
