I wanted something a little different to build. Had to be fixed gear and fit a 20cc gas .
Found plans for the PZL P11 on Outer Zone. It was smaller than I wanted so had to enlarged them. They didn't look too clear but thought they would be ok. I decided on 20% so took the file to kwik kopy. The plans are low res. Lots of the text on the plans are unreadable, but the outline and formers looked ok. A quick measurment shows about a 64in ws. Laying out the engine shows dle20cc a little too big. So going to use my evolution 15cc instead.

As each wing has 3 sections and a 3 piece spare, I chose to tackle that first. Measuring ribs and spar position shows a variation on the middle section ( could be from the low res and my chosen reference points) so that had to be compensated for.

It was time to start cutting.

Started assembly of the first wing outer section. Ribs were glued to the outer spar. The middle and inner rib sections were left floating to allow for adjustments.
Assembling the wing panels shows the first big mistake. The inner spar was glued to the top of the middle spar instead of the bottom of mid spar.   Embarrassed
First pic shows the spars laid out and I have them out of position.  Cry

Had to cut out the spar and build a new one. Building the rest went better. I also managed to line up the two wing spars fairly well,

The fuse was started as I would need this to be able to work on wing center section.
Plans call for stringers but I am going to sheet it to match full size. This meant some changes to the build.
I made a box structure and added formers. Then it was time to start sheeting.

Added anchor points for the struts and some landing gear block.
With the planking far enough along some of the box structure was removed to save weight.
Fuselage needs a good sanding but that will wait for another day.

Started on the tail frame. Probably going to sheet them too.

Sheeted the tail feathers and gave them a rough sanding. Still need to be hinged and install on fuselage.

Spent time figuring out how I was going to mount the wing and blend it into the body.
Once that was done, the next step was sheeting the top inner sections of the wings. As each wing has 3 sections with diferent angles, they needed lots of sanding to get a good  fit. Finishing the wingtips  and cut out the ailerons are pending.

Discovered the wing twisted while skinning the center sections and I haven't been able to remove it.  Cry
I removed a wing skin and applied a new one while 'reverse' twisting but that failed to make any change. I think the problem is due to the difference in airfoil taper in the sections. Wondering if a rear spar would have helped hold the shape.
I am abandoning this build. May use the fuselage for some future sport build.
