I knew it was not me and later found stbd. ail. had seperated with all the hinges still in it and unbroken. They pulled clean out of the wing and were as slick at smooth plastic...no wood on the wing half of the hinges.
If you built the plane and maintain the plane and fly the plane then it was your fault!!!
Sorry to be so late in reply, they were Sig Hinges or Great Planes, will not use either again.
How can the brand of hinge be the cause. You said that pulled straight out and were smooth with no glue on them. Did you rough them up before installing them? Did you use enough glue??
Also I learned a long time ago to pin them best insurance against hinge failure.
Not trying to start a major war over this but IMHO all crashes are the pilots fault.
