Building Possibly My Last Multicopter
I left the hobby in 2022 after the crash of my Tarot Ironman due to a propeller blade separation resulting in complete destruction of the aircraft. Since then I have been flying an old DJI MAvic Pro that I bought used from a photographer who wanted to upgrade. Anyway, recently l've thought about wanting to build one more multicopter. I enjoyed the challenges of building one plus the satisfaction of flying something I built. So I decided to once again embark on a build project. My needs…

hi,I am fresh. Now, i was researching the copter with four fans. However , i was confused about the problems, like" how many size of the fans and speed of the motor for loading the copers? so, if anyone know how to solve the problems. could you help me for recommanding some material or send to my email: jacob_fan@foxmail.com. Thanks!
The process of elimination to the root cause can also be a bad battery that goes low in voltage with a current drain yet shows a good float voltage when not used. I know that if the battery is drained it tips the copter if I try to use it again. Make sure the level routine is done properly with trims neutral.
One thing I do before trying lift off is to throttle up on the ground just to the point where I can move the quad, but not enough to lift off. Then nudge all my sticks to see if they move the quad in the direction that I want it to.
Chris is right. The APM is oriented for +, so you MUST use + mode.
His APM is oriented for + (facing an arm), too. So it should set for + mode. I'd guess that the motors are connected in the wrong order.
After looking at your video the quad is attempting to "roll".
I had this same issue and found that the quad was set for X rather than + . Your quad has red tape on only one arm which implies a + configuration and it may be configured for X but may be trying to fly in the + mode.
Try clearing your configuration and do a config from the very beginning.
Also: run the "Motors" test in the CLI, which will tell you if you've hooked up your PDB right:

Check your radio pitch trimming. Make sure everything's in the middle and calibrate the radio. Either that or the motors are not turning in the right directions or the props are on wrong. Put up a slower shot of the motors moving, and a still shot of the props, so we can see better. (Oragne arm should be CW, and the other arm should be CCW)
Ethan: ok. I will try that. Thanks.
Adli Shahanza:
I had an issue very similar with my quad at first. Triple-check the correct wiring on the power distribution board. Make sure you have the orange and white signal wires going to the ESCs in the proper order (front, back, left and right). I'm fairly certain that's what the problem is.
Randy: Already try both of it (+/x mode). Still the same.
