This month’s column is based on building the Stinson SR-9, blog No. 10, on rcmodel.com. For direct access to all of my blog entries on this (or any other) project, go to the archives tab partway down my home page and click the appropriate subject under categories.
It’s been a while since I have done any work that counts on this airplane, in fact, I have to confess that I’ve been letting it gather dust in my shop for about a year. I set the Stinson aside to work on the old FlyLine Great Lakes Trainer kit. That project turned into a twenty-nine-installment blog series… check the archives tab on my home page if you missed it. Just as that project ended up letting me finish it, it became clear that I needed to build a pre-production TigerKitten from the new kit my friends at Premier Balsa Kits are introducing, in order to help check out that new product for them. As you have probably figured out by now, I’m not capable of doing anything relating to model airplanes the quick way, so the Stinson spent several more months getting dusty on the back workbench.
At the point I made the last blog entry on the Stinson project I’d gotten the tail surfaces built up along with the left wing to the point of adding all the leading edge sheet and the capstrips. What was left to document was the final sanding to shape of the wing structure along with building the flap and aileron. Since building the right wing is essentially a mirror image operation, I planned to do that off-camera, intending to pick up the blog as I started work on the fuselage. All that worked out just as planned, but while I was working on those two other airplanes I had to replace my old computer. The new one works way better, but in the process of changing to a new operating system and to different image processing software, guess what happened to all those images of building the aileron and so on?
So, I shot some after-the-fact images of one fully sheeted and sanded wing along with several views of the completed ailerons and flaps to give you an idea of what that part of the structure is supposed to look like. In the event you might be using my notes as a guide to building your own SR-9, don’t worry. The kit instruction book is more than sufficient to get you through without my help. Let’s have a look at these catch-up photos. (All this stuff is covered in Stinson blog No. 9 on www.rcmodel.com)
Let’s get on with building the fuselage. In order to provide the most useful evaluation of this kit for those of you who are reading this, I’m following the construction steps in exactly the order they are presented in the instruction manual. The book says, build the tail surfaces first, then the wing panels and finally the fuselage, so that’s exactly what I’m doing. Speaking of the instruction manual, I’m going to suggest that you not even think of trying to build the fuselage without it. Unlike smaller models you may have built before, the fuselage formers on this one are not one or two complex shapes cut from appropriate pieces of sheet balsa…they are built up, most of them from over a dozen parts each, and you can’t identify the players without a program. With all that said, let’s build.
That’s all we have room for here, but there’s more. Go to http://www.rcmodel.com/2012/07/building-the-stinson-sr-9-10/ to see all the rest of the details of Stinson blog No. 10.
