Fun plane, after you sort out the garbage undercarriage issues.. Easiest fix - Use the rear float legs in the box to reinforce the main gear. Bend the fuselage mount point on the rear legs straight, Take off the plastic main gear retainers, Place the float legs on top of the main gear legs, then flip the retainers over and refasten. The additional leg-set should loop behind the main gear, with the 90 degree bent leg ends pointing forward. Fasten both together near the wheel hub with a small zip-tie. Repeat for both sides. Fyi - Mine hasn't needed any adjustment since discovering this fix. also seriously reduces gouging of the fuselage in front and behind the wheel pants, and extends the life of the wheel pants themselves. Try 4S if you dare.. scary fun. Happy trails
