From this video. 2:20 or so.

By 3D I mean more than 1.5:1 thrust to weight to get punch out of a hover and the ability to do high energy moves. My Katana is close to 2:1. My Mintor 22 power Velox is more like 1.5:1which is floaty and adequate. I know I am probably asking a lot out of this size motor as glow engines really did not cut it, hence the exclusivity of electric in this size for the major manufacturers.

I was also checking out the pilot-rc 53" models as they look like a simple cut off of the motor box and an overlay of some light ply and you could easily mount up this baby. Kind of pricy for a experiment though. The Value hobby looks more economical as well as using inexpensive standard servos.

The seagull model looks like a lot of fun. Like to see a video.
