Firstly, I have to say I absolutely love this plane, but.....
1) The nose is too light.. So when you get one, DO NOT throw away the clear nose protection that it shipped with, keep it there and tape it on.
2) Never fly in any kind of wind, fly it when the leaves on trees are barely rustling...otherwise the wind will control it or take it on a long ride ;-)
3) Take time to work out the controls, and remember it is proportional to a certain extent.. so don't push the controls to extremes all the time (otherwise you'll just keep stalling it)
Once you have had a good few flights, I'm sure you will get it above tree level as I have and also flying back to your hand!
Hope this helps...good luck
