Got two flights on mine then blew up my lithium ion (picture one). Here is where I am at now. Replaced the light ply with normal ply and triangle reinforced every joint back to the wing. The wing bolt mount looked a bit weak to me so I reinforced with epoxy and will put another plate on top of real ply. Loving inverted spins and tumbles it would only be a matter of time till they seperated and made the fuselage that much faster without the wing. Tomorrow I will glass reinforced the landing gear mount and wing center. Like the plane. Can't wait to get it back in the air.
