RE: Diving on downwind?
Hhhmmmmmmmm! Well, lots of ideas to consider. First, the question centered about a plane that flew very consistently regardless of wind conditions, and didn't seem to need any major elevator changes upwind, or downwind. Then, fighting it to keep from going into a dive on the downwind side. I have to examine the power issue, possibly the engine is gradually losing power, though it would seem I'd notice that more on the t/o and climb-except it's a big wing with lots of lift. Another thought is what would happen if the thrust angle of the engine changed? Or, perhaps a loose elevator hinge. The wing is held on with rubber bands, maybe I've somehow changed the incidence without knowing. I have started to tear the plane down and see if I can figure it out. It's kind of like you get in your car one day and notice it just isn't running right, and the mechanic says there's nothing wrong with it.
