It looks like both spars broke in half. Niether were reinforced and the bottom wing looked like it could use a little more epoxy as there was very little bonding the wings together. The top wing had an adequate amount bonded to the metal center rib because there are torn wood fibres still bonded. Pretty sure the bottom wing failed first then the top wing seperated....but it was still instantaneous. Still haven't hosed off the mud from the DL-50 so dont know if it survived but it looks like most of the electronics came out OK...we'll see tonight.
