About NASS and Control Line Speed

North American Speed Society - NASS
is the Special Interest Group of Control Line Speed and is associated with the Academy of Model Aeronautics. As such, NASS helps formulate rules that promote the interest of the speed fraternity and supports speed competitons in North America. It is recommended that speed fliers join NASS so that NASS can represent your views and ideas to the AMA. The AMA has called upon the SIGs to run the National Aeromodeling Championships (NATS). NASS now runs the speed portion of the NATS.

The NASS newsletter available to members is called SPEED TIMES and is published four times a year. The newsletter is approximately 36 - 42 pages, and contains contest listings and results; construction articles and plans; advertisements for planes, engines, and other parts; a list of the members; and a list of speed equipment suppliers.

What is Control Line Speed?
The purpose of the speed event is to fly a control line (tethered) model airplane over a fixed distance in the shortest time possible. One of the model's wings is attached to the control handle with the use of a thin steel wire (or wires), the control line. The handle is held by the flier, who rotates around the center pole called the pylon while controlling the flight altitude. Speed competition is divided into classes based on engine size/type and aircraft design. Control line speed planes are unique, they are small and very streamlined to minimize drag. Some models are of unusual asymmetric design, with only one wing on the inboard side of the fuselage and the stabilizer on the outboard side. The purpose of this shape is to have as much as possible of the control line wire hidden inside the wing to minimize drag. Some models look like real planes and are beautifully finished. Speed models use high performance piston and pulsed jet engines to reach high speeds that have hit 200 mph.
