Avatar AT-99 “Scorpion” Gunship

By: David Windestål

First time I saw the bicopters in Avatar I knew I had to build one, some day. That day has now come. Together with Chad from flitetest we created our take on the dreamed up copter.

Brass tube bent for the dihedral of the motors


Carbon fiber tubes that will act like bushings for the rotating arms.


Square carbon tubes with a round inside diameter that perfectly fits on the carbon tubes.


I sawed of two small pieces and glued them to the base to act as stops and reduce the friction of the rotating carbon arms.


Servo horns mounted


Servos mounted along with the string that holds the arms together, preventing them from sliding apart.


Motor mounts.


Motor in place.


Plywood plate to mount the KK board.


HK-KK board flashed with the ”Power tower” software.


Prototype done. It hovers quite nice but pendulums when you pilot it incorrectly.


Changed to Hobbyking MI servos for better control.


Trimmed in and ready for the body. This is where Chad comes into the picture.


Shroud made from depron.


Cockpit made from dollar tree foam.


The body taking shape.


Body painted.


Attaching the electronics.


Shrouds in place


Lots of hotglue.


Tail fins in place. Not much left now.


Almost ready. Just need some guns. However I didn’t take any pictures after this point and you just have to watch the video to see more:

What was the total cost? and could the same parts be used in a skeleton/frame design?

Could you make a smaller version with, say, two turnigy 1811 2900kv and corona 9g digital servos?

A simple fix would have been to add an inexpensive gyro, bananahobby has one for the mini f-22 raptor that can be used in most any bird. Sure would like to see this fly with stability, very cool build, and one that could be a kit. Keep up the great work, you guys are AWSOME!!!

Did you guys ever get the pendulum effect fixed? I'd love to see this fly smoothly. How about any other bicopter concepts. I've kind of been obsessed with the various motor tilt mechanisms lately.

I'm working on a design that would fly perfectly with this general setup! Could I get some direction as to where I can purchase these parts? I would appreciate it so much.
