I'm not really looking to upgrade this heli (not for a good while, at least), and a good thing too. Finally had my first major "hard landing". I let it get a little too far away at a fairly low altitude, and lost orientation. I most likely would have been able to get it sorted out if I'd had more altitude. I'll have to keep it in mind to only fly low in close. About $60.00 to $70.00 of replacement part damage was done. CNC and CF parts would have just upped that figure.
