The first, and MOST important thing you need to learn is....
your going to get shot down A LOT !!! Get use to it.!!!
Even the "hot shots" get jumped and end up dead, so you are in with the right crowd.
Treat each flight as a learning experiance, and try not to get too frustrated. Its a game, have fun !! Lots of great people in both the training arena and the main arena will help you out.
Training arena---- ask for help in almost anything and most people will give you a hand weather its learning a trick or two, or just having someone be a target for ya to learn the proper lead.
Main Arena---- after you get shot down, if ya ask the guy who just killed ya "how'd ya do that?" or "What did I do wrong?", most will give ya a civil answer, those that don't most likely just got lucky and have no idea how they got ya
Good luck, practice is all ya need !
