Speed 400 racing in the CMPRA is run to local Calgary rules. These rules are set to keep things reasonably simple for beginners to both electric flight and to racing. The racing is both close and exciting. In summary the model rules consist of:

• 6V Speed 400 motor of Graupner or similar manufacture.
• Model must have a minimum of 150 sq ins wing area including any area inside the fuselage but excluding any tailplane area.
• A maximum of 8 NiCd or NiMH cells.
• APC 5x5 E-propeller.

A race consists of 10 laps of a triangular course 200' x 200' x 60'. Cutting one pylon results in a 15 second penalty, cutting two pylons means disqualification from the heat. We use a flying start with a 20 second countdown to allow pilots to launch and get into position. Crossing the start line early results in a cut being awarded.
