Chris,

This may be of no use to you but for comparison =85 = Warp-Drive blades come (optional) with a nickel leading edge bonded into th= e carbon fiber.

I=92m surprised IVO doesn=92t offer this method, as = it is much superior to taping.

I had my forth flight yester= day.  I am still just circling the field.  Everything was going w= ell. Temps and pressures were all well in the green and I was "playing= ' (ok, a kinda cavalier term for testing) with prop pitch, trim and pow= er settings when I suddenly felt a distinct, slight to moderate vibration c= oming from the rear of the plane.  I called the tower and with calm wi= nds was cleared for any runway.  I did a tight right turn to 22 and landed.  Has it been mentioned that these canard= s really don't want to land...I floated quite a bit down the runway...gotta= not try to bleed off speed by slightly lifting the nose.....damned bad Ces= sna habits ;-)

Anyway, I landed and&nb= sp;taxied back to the hangar, the vibration had stopped.  I got out an= d did my quick inspection and it was immediately obvious that one of t= he prop leading edge tapes had departed the craft and another was starting to= tear off.  Well, at least it seems I quickly discovered the problem..= .kinda what testing is all about.

This is an IVO in fligh= t adjustable prop on my Velocity.  I have been using the stainless ste= el prop tape as provided by IVO.  I used the same tape during ground testing, but replaced it all just before first flight.  Interestingly= , it was pretty difficult to get off...as in it required quite a bit of for= ce.  I did have some issue with the tape un-attaching a bit durin= g ground testing at the edges but had hoped it would be okay once I replaced it and secured it better.

IVO has an online video= showing how to install.  It is quite straight forward, but I did note= they now add some superglue to the edges of the tape.  I do not recal= l that being a part of it when I got the prop, however, I did see the video = before the latest tape replacement and I DID add the superglue to the leadi= ng edge.  I also was very thorough when cleaning the prop before = adding the tape....I think I used Acetone for this step.

So? What say ye?  Ideas= , comments etc.  I had one person mention that they don't like the tap= e but understand its use to help protect the prop.  Do we know if it is doing more than protecting from minor fod and, I guess rain??

Thanks in advance folks.
