1/2A Combat
1/2A Combat is an easy event to get into if you like the idea of combat! Motor size is 1.5cc with no restrictions on model size or fuel mixtures. 1/2A Combat is flown over grass with a 3 meter radius centre circle for the pilots to remain inside of whilst their plane is airborne. There are 2 competitors flying at once in the same circle, each competitor is allowed 1 model per bout.
Both competitors models have a paper streamer attached to the centre line of the model and the idea is to take as many cuts on the opponents streamer as possible. The winner is determined by, at the end of the 4-minute bout, the larger score of both airtime and cuts added together.
