The Aerobird Extreme handles the wind really well, it's quite heavy and has a huge wingspan (55"). It flies in wind that the Commander and Challenger just turn turtle in!
Indications that it the wind causing problems can be any of the following:
Fails to turn into the wind direction
Turns upside-down for no apparent reason!
Suddenly dives
Suddenly gains altitude, stalls, comes back down again very quickly

Yeah, what Tim said!!

The plane will just not be that fun to fly. You'll see what we mean when you give it a try on a 0 wind day or evening. It'll be a totally different plane and you'll enjoy the heck out of it.
