This is a remix of Phredie's great ducted micro frame.
I made this after speaking to a buddy over at quadcopter.at. He flew my whoop some days ago and we began to talk about improvements. So the majority of the changes I charge to noctaro.
I made the walls slightly thicker - my printer need needs at least 2 1/2 nozzle widths to stay together, otherwise they will peel.
I also removed the "swirl" in the end of the ducts and added holes to compensate for the added thickness and permit for air to flow better out of the ducts.
I feel, that this frame is more responsive than Phredie's original. And for me it does not break fast. It definitely is a top notch louder because of the holes.
When decreasing throttle, the quad sagged. Now I descent smoother.
This is also a customizer, you can adjust the engine diameter for more, wall widths, heights and the holes.
Print it with 100 percent infill. You can print it pretty fast with outcomes. I have set up that this frame prints in about an hour.
The default settings that are customizer are shown by the connected STL.

Micro Receiver of your choice, I use this one with my Turnigy Evolution.
I would highly suggest to get the 50C batteries, they are twice as expensive as the 25C ones, but have more punch get at least 12 batteries you can charge the first till you're done with the last.
Do not forget to break on your motors.
