No mate, I'm referring to the side mount with the 4mm hole that the cabane is bolted to. There is a big step up to where it meets up with the top turtle deck. It looks like you have filled it out to match the alloy cover. On my pic it has RH OUT wrote on it.

Right. I certainly did add filler to both front and back strut mount locations. Mine is not going to have the bent up aluminum strut covers so I had to handle them a little differently.

Thanks, I had not even thought about the rear mount as of yet, I was leaving my options open as to how I was going to handle the alloy in these areas as well.

The redo of the foam on the bottom has worked out very well. Mich would you have any close up pics of how you applied the filler for the front and rear cabane mounts? It looks as if I will need to run some thin .8mm ply butting up to the top deck ply on the sides as well.

Id be happy to add some detail shots of that area, Terry. Unfortunately I’m out of town so it will be a couple days.

I found that I had to fill the areas where the edges of the .8mm ply terminate - all the way down the fuselage. I used fairly dense balsa. If you don’t do this you’ll see unsightly terminations under the covering.

Terry, here's how I filled the cabane front mount areas. I used a hardwood disk (without the bolt hole drilled out yet) for the mount hole area and a soft balsa triangle around it. After glued in I drilled from the inside out using the existing hole for perfect alignment. All of this has to be sanded to desired planes, of course. Fortunately, it doesn't have to be exactly perfect because all of this is ultimately covered with sheet metal.

EDIT: I saturated the hardwood disk, which was end grain, with thin CA glue for better compression strength.

You'll also see how I filled the bottom of the .8mm top sheeting all the way to the back of the turtleneck

I sawed the hardwood disk out of a wooden rod.

Balsa filler below the .8mm sheeting all the way to
the back of the turtle deck.

Thanks for the pics and cometary, pretty much what I had envisaged. I think I may need to add some thin balsa all the way along the fuselage to get that smooth transition of the fabric.
An up date on my Pilot.
