@alan0043 No kidding!
This is kinda fun to see, I've been building little things like this for a quite a while using parts from the toy quadcopter bin. I've been using 8mm motors, little Chinese receivers, and micro brushed esc's for a long time. Its fun to have one with some stabilization to play with! I've had the best luck on ones I've designed in the past by using an elevator channel too. I wonder if there will ever be a way to add that to this system?
A lot of my micro builds have had 4 channels but the "ugly duckling" only has differential thrust and an elevator:
I've done some more tuning on this ^ little guy since the video. Actually flies really well now.
I see some other sea ducks on here already, I think I'll have to do it again with the new EZ system and see how it compares!
