I keep telling my friends who fly APC, nothing else. After flying APC on one of our octos for months and not breaking a single one, I was told by a friend to try some carbon/nylon reinforced props from MK, and they broke so easily, super brittle, I felt like if I look at them for too long they would break, and I just can't fly with that in mind lol. APC just don't break and give great performance, efficiency and reliability.
Yep its no coincidence that quality kit works best. I often think its the reason people have so much trouble with their builds $10 speed controllers $15 motors and $2 props might not be the way to performance.
