I bought a Tailwind W8 in August. Has an 0-200 for power and a Warpe Drive ground adjustable 3 blade prop. The protractor came with it. This video answered the questions I had. Very informative for us " first timers" with a ground adjustable prop.
Seems like a jig made to go on the flat face at the hub, and and adjustable outboard portion on the TE/LE of the blade would be simpler, maybe supplied by the prop manufacturer.
But a propellor has a helical twist... Closer to the center has a greater angle of attack... further at the tip has a shallow angle of attack. So if I have a 50 inch prop that must be set at 30 inches forward for each rotation (50x30), every point on the blade should go 30" corkscrew forward for one rotation. So the degrees I set it has to be calculated for an exact radius out from the center, not just some random point on the blade where the measuring tool stops or some space somewhere at the tip.
But the tool will stop at the same point on each blade. All that matters is that the blades have the same angle. The exact pitch isn't important and can be changed, that's why you have an adjustable prop.
Could have measured from the prop tip to where the tool becomes snug as a way of double checking that the tool is placed at exact same radius from the center of the hub. This of course assumes the distance from the hub center to the tip of all props are the same.
Francis Castiglione No, you don’t need to compare different props at all, it’s strictly about the props angle relative to the plane. You want to be consistent between blades on the same prop but you treat other different props as their own thing.

Good information, but way too much explanation. I hope most people don't need to hear the same thing three different ways... If they do they probably shouldn't be learning about balancing a prop lol

Thank you, helped me
Thanks, that was a good video
great job !!!

Very nice.... thank you
What is the theoretical distance (as % of total prop length) from the center of hub for setting pitch?
propeller material from carbon / metal material? thanks
I think you should also be checking the 'tracking' so assure the blades are all going through the same arc

Its basic training for beginners here!! sounds like you need no help go play!

How much sir! Aircraft
Thank god for the fast forward button! 18 minutes to explain what the whirlwind instructions do in 3.
And your videos take how long?

If you're not into redundancy you probably shouldn't be flying.
This guy is using a torque wrench as a ratchet??? Yeah, I'm not buying or listening to ANYTHING this fool has to say.
With a name like yours who would listen to you?
