You'll need a joystick to start, a twisty stick, is recommended. Cheapo's cost about $30. Once that burns out, which for me was about a month, you can go to a more robost stick, CH I'll cost about about a buck. But dont waste money on that untill your addicted.
Peddles another buck. Which I hope my wife gets me for my burpday, which is coming up
Track IR another few more bucks.
Now they have support for multi-monitor drivers.
So as everyone says here, practice offline, get the flight controls down, and learn basic manuavers. Once done, the training arena would be a helpful place to go up with a trainer. THe schedules are posted.
Then check out the Late War, but please, alwas ask to jump in someones plane before you do that.
Cheers
