Hey guys, I built an f450 quadcopter model. I want to purchase another battery but I don't know how to go about choosing one. Any ideas, thoughts, or recommendations when it comes to batteries. Also, in my research for the right propellers for my drone I've come across two different designs. One is more rounded and smooth shaped. The other is more sharp and triangular in shape (it is this shape that I see on toy rc copters). I also see this prop shape on most youtube videos I see concerning drones. My question is does the shape of the propeller make a difference? Is one more efficient than the other? Cheers!
Hello! I am new in the community and want to ask you a question. I built quad on F450 with APM 2.6 on board. Electronics works good, everything calibrated. APM is vibro-dumped. But it flipped several times because of wrong pids settings. First time it flipped when in guided mode it banked back for airbrake. And second flipover was whan in RTL it descended. There was huge diagonal wobbling and crash... ( When in Stab, AltHold or Loiter mode - it is good and stable on slow speeds. I`m really upset because I can`t be sure in my copter and I can`t fly as I want - high, far and the most important - safely in all situations. I also built several planes on Arduplane - very satisfied with them. Can anyone with advice how to setup comfotable trustworthy pids? I read a lot articles about the issue, but theory is not practic ) Thanks in advance! And sorry for possible mistakes in English)
