Assembly

From this
To there
The assembling of the frame is quite straightforward. I stick the Naza Flight controller just in the middle of the bottom plate to keep it close as possible to the craft center of gravity.
The only tricky part is to solder the battery cable and the ESC power on the bottom plate. I doubled/tripled check it because big currents are going to pass trough those cables. around 16Amp through the battery cable and 4 Amps per ESC. I have insulated the soldering by adding some hot glue on top.
I have doubled/tripled check the connection order of the ESC to the Naza to respect the motor position and rotation as following:
I momentarily connect the ESC to the motors by using Chocolate bar electrical connectors to easily identify and switch the motor cable before the final soldering to have the motor spinning the right direction during the setup phase.
The ESC are connected to the Naza flight controller by using standard servo connector. Because the ESC doesn't have to power the Naza flight controller i cut the red wire on each of the ESC to Naza connector.
I'm using velcros to hold the 2 batteries under the frame. I keep the top free for the GPS antenna and receiver antenna. Those 3 antennas are hold to the frame by using the GPS holder kit.
I saw most of the F450 config holding the batteries on the top plate. it's probably safer to secured the batteries but any way i prefer to keep the top plate free to hold and fix antennas and future OSD (on screen display).
This is the final result.
