Model aircraft control

Claim 1

In combination with model aircraft having wings, fuselage, a motor assembly and throttle valve lever, and a pivotally mounted elevator, a control comprising: a handle housing being fabricated in complementary section halves which follow a line of cut corresponding to the center line of the thickness dimension of said housing, said halves forming a grip portion having a cavity into which the index finger maybe disposed and a second cavity into which the remaining fingers of the controller maybe disposed, and a hollow housing portion including a center bar disposed in substantial alignment with the radius formed by said model aircraft, said center bar being slidably mounted in a slot disposed in said housing portion along where said radius, a pair of radius arms being disposed distally from the terminal end adjacent said aircraft and projected sidewardly from said center bar and being pivotally mounted at the terminal end opposite said center bar to said handle portion, said radius arms and said handle bar being pivotally connected by links, said handle-housing including operating lever disposed journally perpendicularly to said center bar to the side of said handle housing having said index finger cavity and being pivotally mounted distally adjacent said index finger housing, said operating lever having a rectilinearly disposed slot in its terminal end opposite said pivot point to ride on a pin of the terminal end opposite of center bar opposite said radius arms, said operating lever being provided with a portion projecting from the exterior side of said housing as a handle and with a finger pull ring fastened to the terminal side of said operating lever adjacent said grip portion in registry with said index finger cavity; in said aircraft a T-plate having its central leg disposed transversely of said fuselage away from said housing-handle and the arms of said plate being slightly angularly disposed toward said housing handle, said T-plate being carried at its center or fulcrum point on a pin which is itself slidably carried in a slot which is cut transversely of said fuselage, an asymmetrical U-shaped plate having oNe leg longer and somewhat straighter than the other in the manner of a hook, and being fastened on the terminal end of the longer leg on said pin fastening and between said T-plate and said portion of said fuselage having said slot, said hooked portion of said U-shaped plate being disposed forwardly with respect to said mounting slot, and a link pivotally fastened distally from the terminal end of said longer leg of said U-shaped plate and a connecting portion which projects away from said housing handle and forwardly with respect to said fuselage; control lines including a pair of elevator control lines fastened substantially parallelly from corresponding ends of said radius arms and the terminal end of said arms of said Tplate and a connecting rod connecting said central portion of said T-plate to said elevator or actuating said elevator and a throttle control cable fastened to the terminal end adjacent said aircraft of said center bar to the terminal end of said shorter leg of said U-shaped plate adjacent said housinghandle, the terminal end opposite said control cable of said shorter leg being connected to said throttle valve lever.
