Beryllium Dragon

Didn't work, at 30 m/s the LY-05 failed with the front wheel friction at 0. Following that I made an attempt and got to 134 m/s on the runway when an LY-01 failed. Putting the LY-01's at 90-270 seems to resolve 95% of the instability issue.

On the last attempt I was able to get the basic craft to 85m/s before instability hit. Take aways are: Phantom force When placing LY-01's they must be perfectly perpendicular with the ground (so try to place them at 90 and 270 on Mk1 fuselages) Small craft must be able to lift off at < 85 m/s or will tumble wildly in the sky Due 1. small craft must be perfectly stable, see 2. and 3.

Yeah, the one I linked had landing gears slightly inverted to keep them level with front gear, when I re-ran the craft with the gears at 90/270 point on fuselage it had better stability, but still did the whole "flip in the air" thing at 70m/s (which is about 40km/h, and you'll never get any real craft off the ground at that velocity). I think what is happening is the force is small, but large enough that it has a significant impact on lighter (smaller) craft.

Steam is awesome! Screenshots in Steam is F12, which is also the Aerodynamic Forces overlay key. http://imgur.com/a/Lvakq The base craft which is just wheels, Mk1 inline cockpit, and a top mounted Juno assembly. While under acceleration the arrow directions usually point north, which means the force is being applied to push it north (which is left). With the steerable wheel there is no indicator (if this means anything I have no idea). The four wheel assembly can generally move up and the down the runway fine (except when turning and the whole thing flips over). Now when you add the steerable and watch the aerodynamic indicator you can generally get a feel for what the craft will do. Without SAS it should drift in the direction the force is pushing it, and with SAS it will overreact violently.

I't not the Juno being attached at the sides of the 1.5m. There is a degree of instability with the craft direction, even at 10-15 m/s I was noticing slight changes in the Yaw as the SAS tried to compensate. Something is causing craft to drift (usually to the left), crafts will spin at high speeds if allowed (and not using the tier 1 steerable wheel). Bad things happen at 35m/s with the steering sensitivity causing significant craft instability. The bouncing we see I suspect is due to craft attempting to stabilize their headings. --------------------------------------------------------------------------------------------------------------------------- The low level of changes in Yaw were noticed while attempting to use a single Juno on the top of the craft. ----------------------------------------------- That craft spun and crashed out at 22m/s

Wheels are totaly broken in 1.1.1, will drift (usually left) and if you have SAS on the controller will overreact destroying the craft.
