To train pattern flying is very tough.....especially the toughest manoveur of all is the straight line........not many people can fly straight lines........The most effective way of training is what i called the 5 man aerobatic training team. two man will stand at the end of the 'flight box' as known in F3A flying. they will tell u your flight line and whether your turnaround manevour has go out of the box or not.......it is a very important basic skill to fly the entire training flight in the box as flying out of the box is severe downgrade in F3A flying.......Then the caller as usual will tell u what to do for ur flight........then the last person in the team will be like a judge and score each of the manevour u had flown.....when the pilot has finish its flight.....everyone will gather and summarise their finding to the pilot.........this is how i actually train before for any F3A compeition.
