UPDATE:

The Sonic trainer (top / shoulder wing) flies great from what I hear, but I have mixed feelings about the low wing version of the Sonic. It's fine with a .25 but many power it up to a .46, and the plane doesn't seem to track well with that power on it. A friend flew recently with his with only a Enya .35 on it and we both handed the radio back and forth and just couldn't believe how erratic it was. I can't imagine every plane being like this, sometimes a fluke happens, but thought I'd give you fair warning.
