I’m not sure about the single seaters, and I think some builds have the mounts for the control cables on the flaps and ailerons on the top (or bottom) opposite to mine, which allows you to unbolt the cable and fold them further giving a tighter fit. But I deffinately had to remove my wings to fit my 2 seater in my garage.
The opening is about 2.3m and the tail feathers are almost that, the wings wider again.
Not a huge issue for me as my wings had to come off anyway but I did expect it to fit!
Maybe mine is different?
