Can someone tell me what is the tracking tolerance on a 3 blades warp drive?
I have 1/4 ‘’difference one one blade on mine. The 2 other blades are tracking exactly the same and my pitch is set perfectly similar on each 3 blades.
Thanks

From the Warp Drive Website: http://www.warpdriveinc.com/faq.html
What is blade tracking and what is the approved tracking tolerance?
1/2 an inch is acceptable. Make sure the blades are all at the same pitch before checking the tracking.

When rotating, the tip of each propeller blade moves in a circle. This circle defines a plane of rotation. If each blade were tracking perfectly, the planes traced by the blade tips would be parallel. Due to several factors, the planes of rotation may not be parallel.

I flew behind a Warp Drive propeller. A half inch seems like a bit much
to me. I always got a little excited when it got close to an eighth inch.
I checked my Warp documents and they mentioned nothing about tracking, so
checked on line. I found one site that recommended 1/8" max. and another
that mentioned 1/16" +or-, which are identical recommendations. I do know
this, though, with a very slow moving ceiling fan, a half inch out of track
will set up a considerable wobble.
