[ION] Can someone explain this? Anti-Gravity? Bug?

[vinny]

Hi Everyone, i play KSP for a couple of months and i must say that i love this game.

I Was reading today the challenge with ion powered crafts and decided to do something for my self, but turns out my small craft keeps bouncing in the air with no power LOL, i think its a bug with the game but its funny to see this, when this happened i was like "what the hell, you are supposed to fly"

I made this video to show how it behaves when it takes off

I don't use any mods, since the OSX version im running has poor performance in comparsion to the windows version

Looks like you built yourself a basic infiniglider. See, most of the parts you used were massless, so the engine deals with them in really weird ways.

Shouldn´t this been posted in the Gameplay questions section?

Id check the center of mass and center of lift if i were you. to me it seems that the center of mass is a good bit behind the center of lift. In my experience aircraft works best if the center of lift is slightly behind the center of mass, it makes the aircraft more stable in high G turns and easier to recover during stalls.

That said, I recently on accident made an infiniglider when trying to rebuild the Fi 156 "Fieseler Storch", a WWII german STOL plane. First I did use a jet engine with nothing but a radiator flap intake with its 40 units of fuel to rely on. The STOL performance was outstanding. at 4 tons takeoff weight it took off at less than 20 meters per second and at low altitude was the faster and more maneuverable than any other aircraft thus far. I later discovered the fact that once airborne pointing the nose 15 degrees up at zero thrust caused the plane to hold a speed of 17-18 m/s and gain half a meter of altitude every second. Goodbye physics. I think Ill make a more detailed post later on with pictures and stuff, since thats not my only plane that I rebuilt from that era.
