Help!
Sprite Drone Diy...

Hi to everybody! I apologize in advance for my poor english...
I have built a lot of ...copters, bi, tri, quad, esa, octo, X8, even a ball with a single blade, but i WANT build a model like the Sprite Drone.
But i don't understand how it control the flight. In which manner it can go left or right? There's any winglet? But i don't have seen no winglets... I'm going crazy...
And, the last question: can i control it with a normal control board like Naza?
Many thanks!

Check the principle of a coaxial collective pitch heli, is the same.

No, not with a dumb box as Naza

openpilot should be able to do it, but beware, is more mechanics than you think in this design ! The control board is your last worry...
You must embed the rotor of a coaxial with collective pitch. See attached

Understood! No pain, no gain! a flybarless coaxial collective pitch is not so hard to make! You are my rescuer!

I love making mechanical things, but that picture just makes my brain hurt!

A lot simpler, but where is the camera ?

I thought you want an exact sprite clone, for same purpose

An exact replica would be the best, and i'll follow this way surely, but for people that are searching for a simpler way, i think may be an alternative solution. At last, it could make the body like the Sprite's body...

What about using two brushless motors and some sort of concoction to drive two different co-axial propellors ? Like we have in those toy Co-axial helis..a shaft inside a shaft kind of assembly.

You need swash plate for at least one, to perform pitch and roll.
