I like 3D printers...
And kersplat again lol. Got one flight and landing, and then another flight with more of a crash into a bunch trees instead of landing.
Think I was pushing the CG back too far trying to gain elevator authority. Flew fine until I touched the rudder and the plane went nuts. Big time yaw instability with differential thrust input.
I'm repairing the damage, adding slightly bigger rudders and adjusting control surfaces instead of pushing CG back further. Both the V-173 and XF5U had full flying tailevator thingies. On mine, the outer surfaces were only ailerons. I'm going to make them act like elevons and see if that's enough.
If not, I'll increase the outer control surface size. And if that doesn't do it, I guess I'll be going with full flying surfaces. Shouldn't be too hard to do, they're already separate pieces after all.
