Status: offline 		Somewhere in there I started to work on making some templates for the starburst pattern common to decathlons and shown on the kit plans. I used a glass plate over the plans, and clear plastic material for the templates, straightedge, and a sharp #11 exacto blade. It was a bit tedious, but not that bad in the end. I intend to use a trim sheet to make the starburst pattern. My thoughts are that white covering won't be as white over the red covering on the rest of the airplane.

I sanded down the epoxy nightmare on the fins, rudder and elevator. One thing I learned in their construction, do not use T pins on small hardwood strips. I used some CA to seal the split. I also beveled the ailerons.

Happy flying and don't glue your fingers together gang!

Status: offline 		Kargo, I'm enjoying this thread. I'm planning to build that one.
I plan to use an LA .15 on it. I've heard that that plane comes out
a little on the heavy side, so sand it thoroughly and keep the
on-board gear light. Enjoy your project!

The one wing side I've built so far turned out very good and strait, the leading edge fit perfectly. That's a lot more than I can say for my last winter's project, which required a lot more sanding and fabrication.

Status: offline 		Hey gang, I've been doing a lot more family stuff and building than posting, so its been a bit. The progress to date;

Wing

I dealt with the gap between the trailing edge pieces with some epoxy, wax paper and a clamp. I pressed the epoxy into the gap with a piece of scrap. Unfortunately I didn't get a picture of the finished result. I'm sure its added some weight, but there is no more gap.

I was not comfortable with the way the servo was mounted, so I messured the length of the Blue Bird BMS 380MG micro servo

http://www.bphobbies.com/view.asp?id=V443293&pid=T886880

and placed to pieces of balsa between the ribs according to its length. I placed them so the sheeting would rest just on top of them. The instructions has you use two ply "servo rails" glued to the sheeting for the stock servo mount. I used those as well. There is 3 pieces of sheeting for each wing side/half (12 total). I soaked the front two pieces in water (which had the most curve) and used Titebond II with rubberbands, clamps and bag weights. After the sheeting was in dry I cut out the hole for the servo mount. The instructions say to mount the servo off-set of the centerline, and I mounted it right up against the wing joint. If I had it to do over, I'd leave some space.
