Oh yeah...the big airwolf is my pride and joy. so many hours put into it. i dont want to go through that again.
The little ones do require a lot of patience as well. Assembly time is almost 5 hrs each from start to finish. Painting is such a pain.
As for mechanics for the little ones, all are NE 260A. It's nice to control 15+ helis with one remote
The Big Airwolf is a 500 T-Rex clone. The walkera Airwolf is 300 scale i think (maybe 250).
Not sure about Mike. He must have moved on and away from this hobby, or maybe just trying avoid shipping overseas. Have you tried these sites:
Kinda pricy, but a lot better quality job than Mike's helis.
