Title: F450 Quadcopter very unstable on KK2.1.5 board Post by: TopGunTejas on December 31, 2016, 04:38:56 PM :help:
Dear members, I am a student who is new in the RC world. I am building my first quadcopter with these specs: Motors: A2212 1400Kv ESC: Dys Simon K esc's Flight controller: KK 2.1.5 with steveis firmware ver: 1.9 Props: 10*4.5 Frame: 45 cm across Well, I have been trying to get this craft in the air since the past month. Once in a while it gets more than 4 feet in the air but it flips and falls down. Since I broke 2 props, I have tied its corners with ropes which are slack enough to allow the quad to reach six feet in the air. But, the quadcopter is very unstable and veers off in one direction or the other :banghead: I need to display this craft at an exhibition on 12th of january, so plzz help me!! I am attaching pictures of my setup. BTW.. I live in Bangalore.. so if anyone is here who could help...that would be greatly appreciated! Thanks in Advance, TopGunTejas.
