Phoenix resurrection, for who is interested in “Taurus’ little brother crash investigation.”
The Orion has plywood ribs and spruce spars. The result of the crash is, one wing and the complete centre section is without any damage and the “impact” section complete fractionized.
The aileron of the undamaged side was still complete functional.
I will rebuilt both sides with lighter material, balsa plywood and the span of the wing will be reduced, 2 x 3 inch, see the study picture.
Study of damage is interesting and important to think over new construction methods.
Last picture is of the past. Complete destroyed midsection and the rubber bands still remarkably well equalized on the dowels? Clean spinner?
For me the servos are from high value, that’s one of the reasons I still mount them in the centre section far away from any impact, the mass of the pushrods of elevator and rudder is my enemy for the servo gear.
I did forget to tell about mounting elastic bands. When you also fly with gliders there is one more reason to mount the rubber bands from front to backside. The TE of the wings of a glider are more fragile. So “over tension” before equalizing can damage them. It is whatever you want.
