This is my third budget 5-inch copter project I have submitted this year. The frame is a chinese iflight XL5 V2 clone, while the engines, ESC, FC, camera and VTC are elements from the Eachine, Tyro109 models. Flysky 8ch receiver. Geprc 5040 propellers, cheap and great at freestyle.
The frame of this copter is relatively light (115 g), but most importantly, extremely durable and resistant to accidents. This copter will ultimately be used for daily exercises of new aerial figures, so the priority was its endurance and I hope that it will cope with this task ;)
I used the arms mounting in the opposite way than in the original, which gave me a full 30 mm space inside the frame for comfortable installation of the stack consisting of 3 elements. Thanks to the built-in and compact design, it protects electronics inside.
The total cost of its construction is about 120 USD.
