I did not get as far this weekend as I thought I would. I had expected to accomplish the basic framming of the wings. Or things to do and I had more prep work to do than I originally thought.


I am going to use a more normal spar system, top and bottom spars on each wing. Those had to be cut. I had place my balsa laminate build board under the magnetic on, started positioning ribs and went oh crap. I ain't ready Where are my spar slots. And hey I can't count, I am short 2 ribs, and I thought I was making 1 extra for a possible RC version down the road. So make 1 more W1a and W2a and use the 2 supposedly spares.


Then it was time to cut spar slots. Well slow down Sherlock, you still ain't firing on all cylinders obviously. I had become pretty heat stressed when I went out this morning to fly my little OS .10 trainer. Ended up on the ground at the end of the 1rst flight.


So I made the needed extra ribs and put them all the rods in the correct order but doubled up. Top and bottom wing ribs slotted at the same time W8,W8 W7, W7 all the way to the middle were it was W2a, W2a, then W4a, W4a, W4a, W4a, and the back to W2a, and continuing the pattern to the last rib on the opposite wing panel. .

I removed the balsa building board from under the magnetic board to avoid it taking a set. I am building on top of a card table with a 2" sheet of insulation foam on top of it. So there are some issues with trueness.


Maybe later this week I can start framing the two wings.


Need to get 4 balsa 1/4" square spar pieces. Also some 1/16" balsa sheet.


I am thinking of building the stab and elevator a bit different than the standard sheet tail. I am strongly considering laminating 1/16 sheet balsa to a core of $tree foam board paper off. Stick L.E. and T.E.s. It should be only slightly heavier than a simple sheet tail, but a bunch stiffer. The stab/elevator will have an area of around 103 square inches. That is not real big but might possibly be pushing 1/8" sheet. I am very open to input about this.
