I sold that helicopter about 2 months after the last video posted of it. But I do have an Align 600 Nitro DFC. Well, it is a DFC kit now lol. I'm actually doing a video series on it right now on how to go through a used helicopter so that you know you have a good heli to fly safely.
Full disclosure, the HK600GT is a sketchy kit. The metal on it seems softer than the other HK series helicopter from them. Do yourself a favor and either get an Align kit, or at the very least, get an ALZRC kit if you are strapped on cash. If you are looking to get a 600 size that is.
