Wade,
I have a Meade 12 inch truss scope. Each time I disassemble and reassemble the scope, I expect to have to collimate it. Each time I move it as a unit, I expect to have to collimate it. There is enough flex in components to change collimation when moving the scope and tolerances are not perfect, so there will be changes to collimation in final assembly (I should imagine even in a collapsible). Rarely, will I find a perfect alignment from one assembly to the next. Even a full tube scope needs a collimation check after being carted from home to a viewing site.
I had a lot more problems before I put heavier springs in my scope. The standard wimpy springs would not hold the mirror in collimation. So, whenever I undid the locking screws to collimate the scope, the mirror would just flop into a different orientation depending on the angle of the scope. See how you go with the heavier springs and Bob's Knobs. It may take some of the pain out of collimating.
Regards, Rob.
