So I've finished the GP PT40 I bought mostly completed on craigslist. Ended up having to cut the tail feathers off and reposition them due to an axial twist in the fuse that was unfixable. Someday I'm going to start a thread on why people use CA on these larger kits... Anyway, got the tailfeathers level to the wing saddle. Had to buy a REALLY long drill because the original builder didn't drill through the bulkheads for the control rod tubes. I went with two aileron servos in the wings instead of the one central one with torque tubes. Let's see, custom motor mount for the brushless...Everything else was pretty straight forward. I spent just enough time on it to make it flyable and not hideous but at the same time recognizing you can't make a silk purse out of a sow's ear. I did experiment with the covering. Multicolored panels and using the monocote solvent to make 'stickers' out of the film for transitions.

I like to take lots of pictures while working on a kit, I've posted most of them on my personal site. Here's a few highlights...(If for some reason anyone is compelled to see all of them, PM me for the url.)...Continue Reading

Craigslist recently brought a partially built Great Planes PT-40 into my shop. Wing and Fuse are mostly built and the rest of the parts, plans and instruction book were all in the box. The guy I bought it from had been building planes since the 70's and got to this point on this one and decided due to failing eyesight and arthritis, he couldn't finish it. We talked for awhile and I gave him what he was asking for it. I gave it only a precusory look while at his house. Once I got home I could see where he had struggled quite a bit, but overall it had good bones. Most seems to be nothing a few hours with the sanding block won't fix and perhaps redo some of the wing sheeting.

So I'll start with a few pics starting with the craigslist ad photo and then some I took once I got it home.
