I would say without doubt the HBFP V2. I have that and a CP V2. The CP is very unforgiving. We all crash when learning and the CP will get damaged no matter how small the crash
I got my CP first because I wanted a better 6 channel heli. I fault that a 4 channel would fly different.
Trust me is does not. I am not saying it is as good when you know what you are doing. What I am saying is that for a newbie learning to fly it's the best heli IMO
I have hit my wooden chair legs, the metal legs on my treadmill the floor etc and all with so much as a broken blade. I would do a fuse mod to protect the 4 in 1 as that is a weak spot IMO.
Also if you can the Phoenix flight sim is fantastic.
You just spend loads of time and money on the CP trying to keep it in the air. 5 - 6 hours charge on a standard battery. Only 1 - 2 hours for the HBFP V2.
