Just starting to get past the "wet behind the ears" stage with this TwinStar and for the life of me I can't figure out what it is aerodynamically that causes the a/c to "shimmy" just before touch-down and right after t/o? It's really nice and stable all the way down in a vertical landing from a high hover and then POOF! It wants to dance within 2 feet of the ground... Conversely, coming up it wants to REALLY jump with translational lift immediately after t/o and then gets super steady about 2-3 feet up coming into a hover. WTF over? There's gotta be something I'm missing here cuz I can't understand what about the ground effect is causing such a huge change right before/after ground contact. If someone with more knowledge and a better grasp of the aerodynamic principles can explain it I'd appreciate it! Thanks in advance! Avbug, you've GOTTA have something to say about this one and I want to learn!
