yeah, that's the beauty of buying at a local vendor. The issues more or less what you are talking about are the motors and they vary quite a bit from heli to heli. So buying online you might be fine, or you might have to exchange it. Just make sure if you get it online that you get it from a reliable vendor.

Honestly there are not many forums for this heli over here. Check over at rcgroups. they have forums for this type of heli.
