This is a remix of Phredie's great ducted micro frame.
I made the walls slightly thicker - my printer need needs at least 2 1/2 nozzle widths for the layers to stay together, otherwise they will peel easily.
I also removed the "swirl" at the end of the ducts and added holes to compensate for the added thickness and allow for air to flow better out of the ducts.
I feel, that this frame is slightly more responsive than Phredie's original. And for me it definitely does not break as quick. It definitely is a notch louder because of the holes.
With the original the quad always sagged quite a bit when decreasing throttle. Now I descent much smoother.
This is also a customizer, you can adjust the motor diameter for the holes, wall widths, heights and much more.
Print it with 100% infill. You can print it pretty fast with still good results. I have slic3r set up in such a way that this frame prints in about an hour.
The attached STL shows the customizer default settings.
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, also get at least 12 batteries, then you can charge the first till you are done with the last.
Do not forget to break in your motors.
