I’ve wanted to build a FPV warbird for a long time and now I finally got to do it!
The airframe is a 1600mm EPO P-51D Gunfighter from Hobbyking.
Enough talking, here is the first part of the build log

The Avatar Gunship Project
I just love being at Chad’s. One evening I asked Chad; Wouldn’t it be cool to build one of those Avatar gunships?
Chads reply: Yes, lets build one now.
Two days later it was done. I did the electronics and Chad did the esthetics. It turned out so well that we did a flitetest episode on it:
As I usually do when I build stuff, I took pictures. Here is the build log for all of you that want to see how we built the Avatar Scorpion Gunship.

Avatar AT-99 “Scorpion” Gunship
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:
In Chads basement
Now that I spend so much time in Chad’s basement, I though I would snap one photo every day I’m down there working and post it so you guys can get a glimpse of what we’re working on. Who knows some of these things might or might not be in the future Flitetest episodes.
Since I’m already behind I’ll post 4 photos today:
This thing will definitely be in a upcoming episodeContinue Reading
Anyone going to the JR Indoor?
Hi guys! I’m finally in the US.

This Saturday the Flitetest crew and I will attend the JR Indoor Electric festival, we’re not going to shoot any official episodes there, just have fun. So if you happen to be going I would love to meet you! And if you’re nice I can introduce you to the flitetest guys as well.
