Please help - M4v2 wont arm

[ebross67]

Hi Everyone,

So, I'm getting really frustrated with the M4v2. It has such a high learning curve that I feel like a preschooler. Please help. I have read through the entire documentation and I'm lost. I just want the ladybird to fly. I have no experience in radio control equipment. The only thing I know are the easy RTF products. I bought a Taranis X9D Plus. I have mounted the M4v2 board and hooked up motors. I was able to get it binded to the radio. I think I got the right channels setup on the Taranis. In the QGC I can see all six channels working. I followed the steps on the m4 installation page. I can't get the copter to arm.

Would having the wrong quotos lic num cuase it not to arm?

Any help would be great.

Thanks,
Erik

Problem after problem. I finally got it to arm. The Flap switch is backward. It has to be up and the Aux2 switch centered. I don't know how to change it. My issue now is the ladybird flips when ever there is throttle added. Maybe something is backward. I don't know.

Sorry for inconveniencing everybody. I will battle through the wiki on my own. Thanks for the help to those who were genuine.

We know building a quad can be a challenge but that's part of the fun for some of us.

Flipping can be caused by many things. Many times people have the motors order connected wrong or they have the wrong rotation of the M4 board or the M4 board is flipped and not set to be flipped.

A good photo of the ladybird and your parameter file will lets us help if you get too frustrated.

All the info is in the wiki but it can get confusing at times.

Larry,

Thank you for your understanding. I've never been a big RC guy. I bought the DJI Phantom, because a coworker bought one and it was the coolest thing. Its been difficult to learn the RC lingo. I have googled and read many hours on PPM, PWM, Mixing, Magnetic Inclination, Calibration, and so on. It is fairly intense for some one with no electronic background. I was psyched that I soldered the connection without ruining the board, lol. I thought building my own Quad would give me a better understanding how they work in general. So I decided to take the leap. I will take screen shoots and upload the params file.

I was ordering more Ladybird propellers, and realized that they come in CW and CCW (that is what it says on the package).
Are the propellers specific to rotational direction? I might have the propellers on the wrong motors. I will check this evening after work.

Thanks,
Erik

I forgot to mention that the motors are CW and CCW and you have to have them in the right place on the Ladybird frame.

Motor one is in the front, left position and the rest in the clockwise direction around the frame. Motor one and three are CW and the others CCW.

I bet you're not surprised by the fact that a CW prop is used on a CW turning motor.

Keep learning, you're almost done.

Hi Larry,

I'm almost there. I have the motors and props on correctly. I built a dipole antenna and get a good GPS lock. I have a radio antenna. The bird is connecting to the radio and arming. My issue now is flight performance. When I arm it and try to fly in manual mode it takes of pitch backwards and rolls right hard. If I take it outside and fly it in position lock mode it stabilizes at a set altitude, but flies in a clockwise circle with no control input. I noticed on the QGS radio settings tab that my setting don't match the 0/700/1400. At 0 throttle mine says -42 and it stops at 3%. The roll is constantly popping at center between 50-58%. When I push the stick far right it pops between 99% and 75% constantly. I have done all the necessary calibrations, and set my areas inclination and declination. Below is the param file.
