I broke my wings on my Axon as well. Did not fold them in flight, but rather, cartwheeled it on the ground. I was using a 1/4 " square dowel. I am able to just replace the spar and re-tape the wings - the rest of the plane survived...
Axon II will be better, be sure to keep us posted on any enhancements you make on the second iteration.
Thanks for sharing!
