DJI NAZA Build - Part 2 - Soldering Preparations



During the build of the hexa, soldering knowledge would come in handy. However for me I haven't done any soldering and this was the first time that I'm doing it, and I have to learn it because this is a DIY hexa. 

We'll seeing my dad when I was kid doing his electronics activities made me think that this is just a simple task we'll I was wrong. With some few trial and errors I already made my first solder. For the build there is a need to create a deans connection for the power connector to the LiPO, the cable we're already part of the kit. Below is my first ever solder.


Then now the second solder, please keep in mind to have a shrink tube available because this is needed to protect the electric cables from scratches. I have to solder the cable I made from above to the hexa body, as seen below. I think this is a good set-up instead of the other hexa kit where power distribution is through electric wires, so this limits the nasty spaghetti cables around the kit.

Don't forget RED is positive and BLACK is negative, you'll have to do this for the other cables from the ESC's.


So now the power is complete and the ESC's are already soldered to the body, so the next step is to prepare the Flight Controller or FC. I bought a NAZA, because I have seen alot of youtube videos that shows how stable the flight of a multi-rotor. Hopefully I can try-out their GPS upgrade and according to their website it's already available.

Below is the kit from NAZA, the main FC Red color and a USB link as well as cables to connect it to the controller. The black one (VSEN) is the one that you use to connect the FC to the computer via USB so that you can manipulate its settings. Also, this has an LED that can identify the status of the aircraft. This is really handy especially when I fly my hexa and the battery is low so I have to land it.


I'm using a JR XG8 transmitter and below is the RG831B receiver.


There's a need to attach the FC to the receiver shown below. Check the correct assignments via the users manual. The only problem that I encountered here is that the connection cables are a little bit bit in which I have to cut a smaller portion so that it can connect to the receiver.


Don't forget the orientation of the NAZA, the M1, M2... cable input should be facing forward. This should able be placed in the middle part of the hexa's body.


As a new RC hobbyist, I had a hard time understanding the binding process, but thank god for youtube I got to understand it. 

Binding is the process in which the transmitter will recognize / bind with the identified receiver. You have to plug in the binding plug as shown below on the BIND socket. I'll discuss the binding process on a separate blog because as a newbie, I didn't knew how will my transmitter talk to the receiver.


There are alot of things that should be prepared for the build and it's really quite interesting to know and understand the complexity of an aircraft. Follow me on my next blog as I try to discuss the other build process.
