I would love to try some serious formation flying using the T-28 Trojan that's available as freeware. This is an excellent freeware aircraft and should be well suited to use for formation work.
I would like to practice with someone who also has this aircraft and has some experience flying it.
Teamspeak is a must as well as a headset for realtime communications.
I have found several servers that have Teamspeak capability with them that we can use. Most of these servers don't ever have anyone else using them at the time.
If you're interested I'm in the Eastern U.S. time zone (GMT -5). Drop me a PM.
