Hasn't been flown or built yet but i'm sure it's gonna fly like a Dream. Still currently sitting on my shelf. Awaiting monetary funding for the electrics. Its an on going fulfillment goal.
Went together easily. It flies like a much bigger heli. I really think its going to be a tuff little beater without being overly heavy. I though the gear drive was going to be loud. Surprisingly it is very smooth and quite. The only real complanate I have it the autorotation bracket have supper coarse self tapping screws. I believe it the only piece of plastic besides the landing and links. They keep loosing just enough to notice. Ill install a longer bolt with a lock nut on the inside. I think it will become 1 of my favorite smaller helis.
Durable where it needs to be. Fits together well. It has some ingenious, simple design in certain areas but overcomplication in some others, nothing egregious. I would prefer a different mounting system for the rear swash servo. It does have an external mounted servo for rudder, which I enjoy for ease of access. Very sharp looking. Started and finished my build today. Programming tomorrow with a maiden in the evening. Can't wait!
