I've found that the 3 axis moments contribute the most to a stable or twitchy characteristic of an airplane. Low values for the ixx (roll), iyy (pitch) and izz (yaw) moments yield very stable airplanes like they're on rails. Increase those values too much and you'll be lucky to keep it in the air. Most are set up somewhere in between as beginners complain about how unmanageable they are if the model rolls back and forth too easily. Adding weight to any model will help it "fall from the sky" as soon as lift drops. Try my Vought Cutlass F7-U. If you try to slow it down, it tip stalls out of the sky. The only way to land it is to come in low and fast and let the ground slow it down after landing. -- ggunners |
