End of Construction Rules

Appendix 1 - Alternate Classes

Due to the varying nature of tracks and facilities, individual clubs may want to run with alternate classes. These classes have previously been used in WGT10, and may be more suitable.

• GT1: For 10.5T motors powered by 1S Lipo/Life with speed controller operating in ‘blinky’ mode as per BRCA approved Blinky ESC’s list. Weight limit 930g.
• GT2: For 10.5T motors powered by 1S Lipo/Life. Boosted ESC. Weight limit 930g.
• GT3: For 17.5T motors powered by 2S Lipo/Life. Weight limit 1150g.

Note: It is suggested that the number of turns is considered a minimum, so running a 13.5T motor in GT1 or GT2 class is fine.
