Airbrakes change CoL (different behavior in VAB and SPH)

[g00bd0g]

Putting airbakes on any vehicle results in a drastic change in CoL regardless of deployed state. CoL does not seem to change with deployed state. Seems to always affect CoL as if deployed. Subsequent airbrake installs do not affect CoL at all. Wierd...

Edit: Further testing show it to be in the VAB only. SPH behavior seems normal.

Pics!

Same craft in SPH and VAB

Well, the reason why it works this way is how the code is handling a lifting surface at zero Angle of Attack. Yes, the airbrake has a lifting coefficient associated with it. So in the VAB (where there is zero AoA), the CoL indicator is moved because the tail fins aren't creating enough lift to overwhelm the airbrake lift coefficient. In the SPH, it's different because the tail fins have enough oomph to override the zero-lift associated with the airbrakes.
