|

Where do you terminate the tape that covers the false rib to avoid an ugly seam? Thanks

I cut mine right at the very tip not going on the leading edge. Mine did not show this way.

my false ribs are 'blended into' the leading edge with body filler - were yours? There really isn't a 'tip' visible anymore.

I folded the tape in half, cut a 45 degree angle on it, so when unfolded there was a nice even point. I then put the point right where the rib joined the spar. This blended in invisibly.

No, I did not blend them in with puddy. I did sand them to a point on the leading edge. I ran the tape right to the very tip before the leading edge. The way the fabric lays it moved right over that tip and the tape was invisible.

Thanks guys.
Dave - I must be telepathetic. I just came in from the shop to read your post, having finished the job exactly the way you described!
Ready to cover left wing.

Are the Highlander false ribs meant to stick up above the wing surface and be a type of micro vortex generator? |

They all seem to stick up higher so I wasn't concerned when I saw mine doing that also. They wouldn't generate any vortex as they are inline with the airflow.

The small MVGs on the leading edges are also in line with airflow. I think Lynn's plane has them. Maybe I'm using the wrong term... |

the reason for the false ribs being slightly higher then the main ribs was to keep a more consistant airfoil between the mains. If they were the same height as the main ribs the overall average level of the fabric between the mains would be lower then at the main ribs. I"m not sure how much difference it would make to have them level but that was what I was told the philosophy was behing the difference in height. They definitely don't act as vortex generators.

Cool, so the extra false rib height is designed to maintain better air flow between the main ribs. Ours are 1/2" higher than the main ribs at the front, tapering down to even at the rib stringer. Would they need any trimming ? |

Dave,
I couldn't tell you if they need to be trimmed, I assume the factory pieces are correct. I didn't think too much more about it because I decided to go with the leading edge wrap :lol:
