For as long as helicopters have been in operation, soft terrain landings have created balancing problems during takeoff and landings. DART Aerospace Bearpaws are constructed of a high density polymer, not plywood, aluminum or composite; this polymer resists cracking, chipping and breaking. The one-piece machined construction ensures consistent and deliberate load transfer. This flexible material deflects under high-point contact loads when landing on rocks or roots; its inherent memory ensures the Bearpaws return to their original shape upon take off. *19" wide footprint.
