Hi guys,



Has anyone had tie down rope clearance issues when mounting the pitot mast on the inboard side of the rib just outboard of the aileron bellcrank?

That's a bit of a tongue twister, so here's a picture that shows what I'm talking about (pitot is outboard side of bellcrank):

I’ve only got a few hours on mine and noticed it in a recent trip.  It really depends on the width of the tie down points.    If they’re narrow, then yeah.   If they’re wide, then no.  



But if I moved the mast outboard I’d still have problems at those places too.   So it’s as broad as it is long. 

I don’t think it’s worth the trouble to reinvent a location and move it from the standard location.

I did the same....pitot is one bay further out.

Mine are in the standard location and I’ve never had any tie down clearance issues in 9 years and nearly 1000 hours. Narrow or wide doesn’t seem to make a difference. I figured Van’s had flight tested the prototype with the pitot in that location, so the odds of having pitot/static accuracy issues would be minimized if I followed the plans on that particular issue.

It’s not an accuracy issue.  It’s the rope running into the pitot tube of the tie down points on the ground are narrow....

I understand the issue. Just putting in my $.02 worth and stating why I made the decision at the time.
