You might want to consider a programmable radio. CNC is good, but I rather save my money for repairs while climbing up the learning curve. Well is just me, people spent their money anyway they like. I see people put in every blings they could get, MOD it anyway they can think of, got a prgramable Tx, High-End CNC head and tail, add heli after heli into their fleet, and I'm surprise to see that they still have trainings kits on their skids and barely can lift their heli for hover without a crash. Well again, people spent their money anyway they like.
