To help ensure a positive and steady progression in our ability to fly slope aerobatic manoeuvres T.O.S.S. have made a change to the layout of our aerobatic league. Moving away from optional K Factor based manoeuvres to mandatory manoeuvres chosen to create a firm foundation of flying skills.
The T.O.S.S. aerobatic league will now consist of three classes A, B, C Class. Competitors will have to start in the C Class and will only move to the next class once they have scored a 60% plus score twice in succession.
