The Interstate TDR-1-- Part 2: Frame by Schwinn, Tricycle Landing Gear

Control of the TDR either came from a control aircraft, usually a Grumman TBF Avenger, with the operator viewing a TV screen showing the view from a camera mounted in the nose of the drone along with a radar altimeter's readout.

Or, the aircraft could be piloted by a human on board for test flights.

The TDR-1 had a remarkably simple design, with a steel tube frame constructed by the Schwinn bicycle company covered with a molded wood frame..  This was important because it didn't use much in the way of strategic materials so it didn't impede the construction of higher priority aircraft.

As before mentioned, the TDR-1 had the option of having a human pilot for test flights, there was a cockpit area.  In addition, the drone had a fixed tricycle landing gear that could be jettisoned during during operation after takeoff for improved performance.
