I store my planes without the wingspars installed so I can quickly remove the wings for transport and push in the spars at field. This Sbach fits in the back of my SUV without the wings being removed so idiot me I took it direct from my wall and into the back of my car forgetting there is no wingspar installed...
Well here's the kicker, first few minutes in the air I knew something was wrong as I could see there was a ton of wing flex and brought her down, but instead of looking for the spar, I just tightened the wing screws more and put her back up in the air ... and down she came.
