The TARZAN TD-1c is the "work horse" of the Theiss Aviation fleet. The construction of the TARZAN is a unique combination of foam, wood, composites, and metal that yield a strong 18’ wingspan craft weighing in at 150 lbs. (empty). This lightweight aircraft is able to carry a payload of 105 lbs. in it’s unmatched payload area totaling over 9 cubic feet.

Because of the construction method and materials used in the TARZAN, harmonic vibrations and shock loads are absorbed throughout the airframe. This ensures that the onboard avionics and payload are protected from potential in flight damage. The TARZAN incorporates a dual control system for safety and system back-up. Each control surface (i.e.: elevators, ailerons, etc.) are split into two surfaces. Each surface is controlled by its own servo. This assures that there will still be positive control of the aircraft should a servo fail in flight.

Because of its light weight and design, the aircraft is able to operate out of small areas. The TARZAN will break ground in 450-475 ft. (fully loaded) and climb out at over 700 ft. per minute. With a usable ceiling of 14,000 ft., the TARZAN cruises at 50 mph. and has a range of 245 miles using the standard 5.5 gallon tank (range may be increased by use of optional auxiliary tanks). When returning from the mission, the TARZAN lands within 500 ft., and can use less distance by utilizing brakes. The aircraft was designed primarily for use by the U.S. Navy, and was fitted with a rugged, spring aluminum landing gear for shipboard use.














For transport or storage, the 18’ wingspan craft folds into a 6’L x 6.5’W x 4.5’H unit using the Theiss Aviation patented folding system. Because of the TARZAN’s ability to fold/unfold (as opposed to being fitted together with parts and tools), and given the light weight of the craft, a single operator and 15 minutes is all that is required to set up or breakdown the complete TARZAN System.

The TARZAN is powered by a Lightning Aircraft Engines (L.A.E.) 302cc powerplant. L.A.E. has been producing some of the industries leading engines for the past ten years. Their engines have been successfully used by various UAV manufacturers in a variety of UAV airframes.














The 302 is noted for its lightweight, hi-output, hi-endurance capabilities. The two cylinder, two-cycle engine with CDI ignition produces 28 hp., and is coupled with a 150 watts, 24 v DC alternator for avionics operations.

The TARZAN is equipped with the Airtronics 94161 Z Servos. Airtronics 94161 Z servos feature custom I.C.'s, Surface Mount Technology (SMT) construction, and splined output shafts for easier control surface adjustments. Molded neoprene vibration isolators and injection-molded servo cases ensure superior strength and long lasting durability. The 94161 Z servos are manufactured with rugged heavy duty gear trains, giving long service under heavy loads.
