RE: Trim Problem
So what happens when you fly inverted lines that don't need much if any down elevator like 45's up and down....?
Or what happens if you only need a touch of down elevator...Enough that mix doesn't really come in enough to keep the model flying straight while inverted but when you push negative corners the model yaws the other way.
Does this mean you use a curve mix?
I have never had a model that used this type of mix. Regardless of how wide body it was.
I guess different strokes for different folks.
Billy check your model for wing tip weight. Are you sure its just yawing and not rolling even a little? The best is the long vertical downlines and pull out and push out in hard corners. This will show the heavy wing very readily. The next thing is to trim it dead leevl upright....and flip it inverted and only apply the little down needed to keep the nose up. Many model will roll ever so slightly here and it means that the wing tip weight is off. Now this is something I find very common. I have only owned 2 models that needed absolutely zero wing tip weight. It is surprising how much a 4-5g weight on a tip can make a huge difference in the model flying.
