Kerbal Space Program

Please note that I am using version 1.0.2.842 - the drop down wouldn't let me select that.

I am also using Kerbal Engineer Redux, version 1.0.16.5. No other mods.

I am playing in Science mode.

When I place two items in a service bay, of the same diameter as the service bay, under certain circumstances, they violently separate upon loading into the launch pad. I have run several tests, mostly with the 2.5 meter service bay, and the 2.5 meter battery. I did a few spot checks with the smaller bay, and the 2.5 meter torque wheel, and they all followed the same pattern.

The following configurations appear to be OK:

• A single battery in the service bay
• Two batteries, one attached top, one attached bottom
• Two batteries in a 2.5 bay, one of then 2.5, one 1.5, stacked one on the other
• Two 1.5 batteries in a 2.5 bay, stacked one on the other
• Two 2.5 batteries and 3 1.5 batteries in a 2.5 bay, arranged large batteries top and bottom, with the smaller batteries connecting - see attached image for visual representation of stable arrangement

The following configurations are unstable:

• two 2.5 batteries in a 2.5 bay, stacked one on the other
• three batteries in a 2.5 bay, stacked in order, 2.5, 1.5, 2.5 - see attached image for visual representation of arrangement, and failure mode
