RE: Lengthning Fuselage
Buzz, I had, with a captial H, a Laniar Explorer 40 trainer. It never flew right. On approach one day a few months back, I got way off line and decided to go right for a go around vs trying to go left which would have brought it over the pits. My instructor thought I was going to hit the power lines, so he grabbed control and tried to go under them. At slow speed, a little down elevator was way to much and he tagged the top 2x6 on a rail fence. Photo below.
The wings and tail were in OK shape, so I built a stick fuselage using the wing and tail. The trainer required a lot of weight under the engine, so I decided to stretch the nose a bit, so I added two inches there. The elevator didn't have any control at landing speed, so I increased the size of the elevators by about 15%. At the suggestion of my instructor, I also added three inches behind the wing. What a difference. I flew it for about a month or so and then lost it in the creek behind the field. I'm not sure just what happened, radio, structural, ???, but it went in like a lawn dart, right into the thickest part of the creek bed, never to be seen again.
I liked that plane so well that I sat aside a 4*60 I was building and built a clone of the one I lost. I had bought a spare wing kit for the explorer, so it was not a big project. I did cut the length ahead of the wing back by 1/2". I needed about 2oz of lead under the engine before, but now there no lead required. It balanced just fine with just a minor move of the battery. I also increased the elevator size a bit more. All I can say is that it is a real pleasure to fly a plane that does what you tell it. I get a lot of comments on it at the field. "Who makes that one". I decided to call it the Rogers phase II.
