This should be easy. Call 1-800-338-4639 and ask for Hanger 9 product support. Take some digital photos of the damage and offer to email the to them imediately while you are on the phone with them. They will likely say that it is not necissary and ask for an address where they can ship the replacement parts. If most of the kit is destroyed they will likely ask you to ship it back to them while they send you a new kit. Horizon Hobby/Hanger 9 has outstanding customer service. Do not waste time with the distributor that you originally purchaced from just have the name of the distributor and purchace date ready for the person you talk to.
