:) I like the connectors to 'look' like they have noting on them. I also put a row of dots using the same black sharpie down the white signal wire close to the connector - allows me to see the connector number after they are plugged in. Happy flying!
I am building a quad and am unclear as to how you determine which motor is #1. I saw a video that said #1 is front left and #2 is front right going clockwise around. I loaded mission planner and the motor test says it starts with the front right motor as A and the next motor going clockwise is B. plugging the wires into the pixhawk so that the motors spin in proper order according to the test the motor locations do not match up to the servo numbers on the pixhawk at all. example- B on the motor test which should be the right back motor is plugged into channel 4 on the apm. I am not clear on which motor should be #1 and what the proper rotation order is. also how does the apm know which way is the front of the quad. I was also told by a tec that the motor order should go front left-back right-front right- back left. it would be great if you can clear this up for me. thanks
Hi Frank, it can appear confusing on the first few builds. You need to open the documentation for the board you are using and look at the diagram for the motor layout (copter.ardupilot.com/wiki/initial-setup/assembly-instructions/connect-escs-and-motors-pixhawk/). These numbers correspond to the numbered connections on the control board. The diagrams usually show the model so place the real model in front of you in the same orientation and you'll see which is which. The above link goes through it in detail. Good luck with the build..
that was very helpful thank you. I finally got it working. is there some way i can send you pictures? I would like your input on some of the builds I am working on. we build for inspection applications so I am fabricating some new frames that have never been built before. my current project involves a fram that has the center open. like a big hole in the middle. I want to mount the apm on one side but am not sure how to configure it. my thinking is that even if I can get it to fly level every time I tried to yaw it would rotate around the amp and not the center of the frame.
If you can post the images onto somewhere you can post a link I'll be happy to take a quick look. I provide FOC support for hobbyists but also provide chargeable support/services for commercial concerns. Let me know.
