Third servo is used to twist the diagonal spars fastening points and to help with turns ( when one of them goes up another one goes down and vice versa)similar to the next video :
Pls watch the last tird of the video.

I wonder what the three-axis stabilization system is- think they have gyros in this thing too? Wonder if it has a glide-lock function.

Fixed Wing 3 Axis Gyro System Overview (6 min 23 sec)


Not sure about the glide lock .Regarding pictures it doesn't have one but if the average dihedral and flapping amplitude aren't very high then it can glide relatively well when the wings are in upper dead point -which usually happen by itself when the motor is stopped.

you can try using this 3 axis gyro to save weight..

I use FY-41 AP for my newest gen. Eagle Orni .. i also have a gyro for the pan and tilt camera onboard ( it's heavier but my big orni can handle the extra weight ).

The frame ,tail assembly remind me on some early Kinkade models.
I personally want to see how it turns only by the this third servo without tail assist.

My understanding is that it will come already equipped with this gyro stabilizer .
I beleave that is better to sale the ornithopter without it and to lower the price with $10 - 15 .
As about the weights

I have one in my collection guys, and my recommendation is - don't waste your money. The design is not bad. It is a little on the fragile side, which I expected, but that wasn't the real problem. Each wing was twisted wrong and came with a shredded dime sized hole in them; bolts were mismatched; nuts were missing; bolts were missing; push rods weren't set up right; heavy adhesive was applied to secure one of the gears; and the nameless brand 3axis gyro was completely defective - leaving the bird with no servo control what so ever. Making matters worse there was no instruction manual either, and the manufacturer is a complete ghost - no name, address, or contact information anywhere, not even on the box. I knew it was a risky buy to begin with, but I still expected more for the money. On one hand I was pissed with all the problems, but on the other hand I bought it with the idea in mind that I was going to remake it completely anyway. In the end it would have been easier and cheaper to build what I wanted from scratch. Lol

Oh I almost forgot, it was assembled with the 3axis stabilizer mounted in such a position that it was touching the smaller gear. Turning on the throttle would have shredded it for sure!

I hope whoever assembles yours does a much better job than the person who did mine. Best of luck.
