Landing gear of Typhoon H, H520 is made of carbon tubes 12x11mm and 10x9mm joint by 2 alu-steel rivets 3,2x6mm through plastic tee. The 12x11mm tube possess 2,5/2mm hole through for gear actuator, for Philips head screw. Actuators itself are mounted by 2 hex screws to main frame of bird. I possess replacement landing gear for sale made of carbon/kevlar tubes and bracket riveted by 4pcs 3,2x8mm, much stronger than originals, packed with 2 black/white dampers. Anybody interested?
