Seems like the 100 would be easy to make it swing to the side. Just make a quick release on the motor side and modify the hinge side to swing wider. Probably need to keep an air strut to control the swing.
Here's the tech of this: Does anyone have a rattle coming from their 100 windows? I noticed some play in the plastic motor arms. Easier to replace or need to sleeve the pivot?
