The frame has a base from the upper face of which radiates a plurality of arms which engage the underside of the skids of the helicopter. By means of a winch mounted on the base, the load frame can be snugged up into a stable flight position beneath the helicopter with the arms firmly engaging the underside of the helicopter skids. There is also disclosed a reel for attachment to the load frame which conveniently can be used to pay out a fire hose or the like from the helicopter in flight.

Abstract: Safety restraining apparatus for a model airplane under power comprising an inverted U-shaped member having a hinged member mounted on the top. The hinged member consists of a pair of spaced arms and legs which limit motion of the hinged member to one direction when the U-shaped member is inserted into the ground. The aircraft with propeller turning is restrained by the hinged member coming into contact with the horizontal stabilizers. The aircraft is released for take off by withdrawing the airplane permitting the hinged member to drop to ground under gravity to be out of the way. One advantage of this invention is that the arms drop out of the way when the airplane is withdrawn. Another advantage of this design is that once the device is mounted in the ground it can be reused any number of times without removing it from the ground. Thus, for a full day of flying, for example, the device is installed, used repeatedly, and then removed when the equipment is to be put away and the area is left.
