Be very careful with wind with that plane. If you're using the stock battery, it doesn't produce a lot of power. Enough to fly, sure, but not well in wind. A little wind is awesome, since you can point the plane into the wind and cut the throttle to float around forever, but too much wind, and that little motor won't be able to push the plane through it and all you'll see is a little dot floating away.

Consider getting a slightly beefier speed control like a 20 or 25 amp, and get some good 8 cell, 2/3A CBP1150 packs from www.cheapbatterypacks.com or wherever you get your batteries from. A good charger will get them charged up in less than 30 minutes.

Also consider getting some better servos with metal gears. The stock servos on the Easystar will strip their gears if you sneeze on them too hard.
