Open Combat

Open Combat is the most frantic, exhilarating, eventful and scariest combat event there is.

This event allows motors up to 6cc to be used, these big beasts create awesome amounts of brute force, but it is an event which reliability is a major key to success.

Having reliable models and motors, which are user friendly and easy to start, will help the competitor go far in this competition.

These models are much larger than that of F2D and 1/2A, but fly just as fast and turn just as tight with no speed loss during the turns.

This event is the one most loved by spectators, as it is known that in this event there is a lot of mid air collisions and lots of confetti from foam models so 2 models are allowed to be used in each bout of open combat.

The winner of the 4-minute combat bout is determined by the amount of cuts and airtime added together.
