Q500 Pylon Racing

Q500 Pylon Racing refers to a class of air racing for radio controlled model aircraft. The sport is similar to the full-scale Red Bull Air Race World Series.

The planes

The planes are made using a variety of methods as encountered with other types of fixed-wing model aircraft, ranging from traditional built-up balsa and lite-ply construction to a full-composite moulded model. The planes are fitted with a standard four-channel aircraft radio. Although the models may be hand-launched, an undercarriage is permitted to facilitate take-offs and landings. Engine size varies from 6.5cc (.40 cu. in.) to 7.5cc (.46 cu. in.).

Basic airframe rules

The wings must have a minimum area of 500 sq. in. with a constant minimum cord of 9.75" and a overall minimum span of 50" up to a maximum of 52". The wing thickness will need to be a minimum of 30mm for at least 47.5" of the span. The fuselage is a very simple construction, box with a 2.25" firewall.
