Information
InformationThis is the build log for my ZMR H250 Cloneout Quadcopter. This is the first multirotor I have ever attempted to build and as such it will be documented and treated as a learning experience. All of the information contained here-in has been gathered and processed into the information you see here.

Build Log- Pre-Build Checklist.
<img src="http://kyau.net/img/ZMR250/prebuild-1.jpg" width="259" height="194" alt=""> - Pull the frame and PDB out of the box.

Motors
- Pull out all the motors, there are long and short screws (separate them).
<img src="http://kyau.net/img/ZMR250/motors-1.jpg" width="259" height="194" alt=""> - Put the propeller shafts on the motors with 4 short screws.
<img src="http://kyau.net/img/ZMR250/motors-2.jpg" width="259" height="194" alt=""> - Assemble the motors to the carbon fiber arms, use 2 long screws and 1 short for each motor (be sure to also seal with loctite). To determine which gets the long vs. short screws, look inside the motor at where the motor leads are attached. If the hole you are putting the screw through is above the motor cables you have to use the short screws so you dont short out the cables.

Battery
- Plugged in the soldering iron (medium tip) to get it hot to solder the battery connector to the PCB.
<img src="http://kyau.net/img/ZMR250/battery-1.jpg" width="259" height="194" alt=""> - Took this time to start charging one of the batteries I bought for the quad.
<img src="http://kyau.net/img/ZMR250/battery-2.jpg" width="259" height="194" alt=""> - Soldered the connector to the board.

ESCs
- Strip the sticker and current heat shrink off of the ESCs.
<img src="http://kyau.net/img/ZMR250/esc-1.jpg" width="259" height="194" alt=""> - Repeat this for all four ESCs.
<img src="http://kyau.net/img/ZMR250/esc-2.jpg" width="259" height="194" alt=""> - Plug the soldering iron back in (fine point tip).
- Desolder all of the motor leads from all four ESCs.
<img src="http://kyau.net/img/ZMR250/esc-3.jpg" width="259" height="194" alt=""> - Cut the motor's lead wires to length for placement of ESCs on arms. Then solder the ESCs to the motors, remember to connect two in a 1:1, 2:2 & 3:3 configuration and the two other motors in a 1:1, 2:3 & 3:2 configuration.
<img src="http://kyau.net/img/ZMR250/esc-4a.jpg" width="259" height="194" alt=""><img src="http://kyau.net/img/ZMR250/esc-4b.jpg" width="259" height="194" alt=""> - Finally we need to test the motors, for this i used the original ESC leads that we de-soldered previously and soldered two of them to one of the spare battery connectors I had to act as a wire harness to be able to spin up the motors with the receiver and transmitter. This allowed me to mark on each which direction they spin so I can make sure i have two CW and two CCW motors. If not go back and resolder your ESCs accordingly.

PDB
- With the ESCs prepared lets move on to the Overcraft Power Distribution Board. First you need to solder 2 separate servo leads, one for the vbat and the other for the buzzer. Make sure to cut them to length before hand or you will be re-cutting/re-soldering like I had to.
<img src="http://kyau.net/img/ZMR250/pdb-1.jpg" width="259" height="194" alt=""> - Mount the flight controller onto the PCB using the nylon standoffs.
