Yarbles In essence it is exactly the same as the scrimmages with recorded results,
Plane matchups and the finer details are agreed by the CO's before the bout. It uses a challenge system, you could refuse a fight as long as you have 2 matches every 6 months. I think that is a little long to go without fighting.
Hopefully in time we will have enough squads to have weekly fights, get in touch with trotter to get access to the forums for it.
It's a great way to improve your team flying only way your going to do that is against better sticks.
