Painting: Left Wing
The wings are now complete and painted. Following are pics of finished product for left wing. I discovered during this phase that a handheld vibratory sander works great for sanding primed coats. I found can manage appearance of orange peel by reducing paint 25% on first pass, and then 40% on second pass of cross coat. Biggest challenge now is avoiding runs.

Paint Scheme Design: Revised Again
I'm back to considering a variation of my original design. I wanted to maintain symmetry around the spinner profile centerline: this is accompolished with the white middle stripe up front. I also wanted the split color scheme to merge at the aft corner of the fuselage, which is done here. This design also eliminates a zigzag stripe, which adds more complexity; everything is linear here. Finally, I wanted to keep the top of the door exterior white so there was not an awkward color transition to the white interior at the top of the door.


I'm hoping to just paint the plastic tip bow covers red, so don't have to fool with painting wing or ailerons red and likewise making sure the stripes match up.

Grass Airstrip Design
I've decided to move forward and design an airfield for the plane someday. It's located on a 40 acre parcel I own, which is entirely wooded. I will have a 200' wide swath logged and the proceeds will go towards development of a 1,400' by 75' wide landing strip. The 75' width will be completely grubbed and regraded. Topsoil will be stripped, stockpiled and then replaced. Seeding, fertilizing and mulching will then follow.

Following is my initial shot at a regrading/drainage plan, based off a site topo survey I performed. Proposed ground in pink, contour interval=1'. Stationing=50'. Several PVC culverts will be constructed under the strip.
Next figure shows a profile of the finished grade centerline, extending at -0.3 and -1.6%, respectively.
Next figure shows some of the cross sections. In general, the runway will be crowned to drain at 1.5% in each direction and then side-slopes will be constructed at 3:1. The site was designed to balance cut/fills with a net quantity moved of 2,800 CY.
