Using colony hub in my contruction make Y and X axis inverted #54

Closed sp991 closed 9 years ago

sp991 commented 10 years ago

The axis is inverted in a manner that SAS or MechJeb can't control the ship as every command result in the opposite direction that it is supposed. Very weird and if I remove the colony hubm then my ship fly straight again. I've tested if in flight!!

...Ok I found out that this bug only happen when the active engines are above the colony hub. So it make impossible all lifting ships impossible to operate.

For sky cranes, toss a probe core on top and control from there.

I had a probe core on top of everything and thought I was controlling from there as it was unmanned but I will try again. Maybe I forgot to right-click and "control from here" on the probe. On Jun 23, 2014 12:49 PM, "Bob Palmer" notifications@github.com wrote:

Closing as this module has been deprecated

sp991 commented 9 years ago

Hello, it does exactly the same thing with the new module! I tried something else and I was able to reproduce the bug with other parts not from your mod. I found out the problem appears when I use a section of light structure as shown is this screen shot. Can you try something like that to see if you get all your control inverted? It's pretty annoying.

inverted axis bug

Stick your engines out more. Stuff gets really weird if it is too close collider-wise.

This is actually just a flaw inherent to KSP. You've put your engines above the center of mass, but the gimbals on them don't understand that, so they still gimbal the same way. So, you try to turn left, they push to the right(which if they were below the CoM would turn the rocket to the left). But the engine is about the CoM, so the rocket turns to the right. Long story short, lower your engines below CoM or turn of the gimbals and let reaction wheels/RCS do the turning

Thank you Andyleap, now that you say that I remember reading exactly the same advice on another forum where people where discussing interplanetary ships built with the engines pulling instead of pushing in order to be more stable as the sipd was assemble in orbit with docking port.
