built 1:16 scale Lockheed EC-121R R/C model
See below YouTube videos for David's next EC-121R model

David Payne, who lives in Oregon, built this 1:16 scale radio control of the Lockheed EC-121R Batcat aircraft. This particular model depicts airplane 67-21493. EC-121R, 67-21493, flying as Batcat 21 was lost on April 25, 1969 with all 18 crew members on board killed.

Here are some specifics about this particular model:

Wingspan is 7.5 feet, length about 7 feet, which makes it approximately a 1:16 scale model. Actual airplane is 123.5 foot wingspan, 116 foot length.

Take off weight is 12 to 14 pounds. Actual airplane maximum takeoff weight is typically about 135,000 pounds (varies with equipment and mission length).

Powered with 4 electric motors with a total of 1.2 kw of power. With a total power of 1.2 Kw total power (all 4 motors), this translates into a total of about 1.6 horsepower (using 746 watts DC per horsepower), or about .4 horsepower per engine. Energy to drive the motors is from a battery pack.

Airplane is equipped with full function flight controls (aileron, elevator, throttles, rudders, retractable gear, flaps, functional oleo strut legs and on-board HD video cameras). The plane also has fully functional landing, taxi, navigation, beacon, strobe and ACL lighting.

David Payne built this radio control (R/C) model. This view shows an early test taxi run with lights illuminated at night. Color, about 143K. Added 07/02/14.

Here are additional images taken later with the R/C EC-121R now with camouflage paint and antennas. One half front view of the EC-121R now with camouflage paint. Color, about 108K.

During his first competition with the airplane, David Payne won first prize with a maximum possible static score and respectable precision flying scores. The first place win qualified David for his first time out for the national championship. This image shows the EC-121R with the award. Color, about 246K.

Images and Information of David Payne's next
EC-121R R/C model hand built to 1:10.5 scale

David Payne provided this information about his next EC-121R R/C model - I am building a new larger scale EC-121R. Will likely be tail number 67-21485. It will be 140" wingspan and 128" long. Covered in thin real aluminum panels and then painted the SE Asia camo. Everything will be detailed to make the plane look real including taxi lights, nav lights, beacons, scale landing gear, real fowler flaps, weather and exhaust staining/oil stains etc. Powered by 4 X 2kw motors. Ramp weight is estimated to be 50 lbs.

The plane will be competing in US Scale Masters (hopefully Summer of 2016).
