(I) Quadcopter project with frame Tarot Iron Man 650, Maytech motors 620kv,T-Motor ESCs and 13'' props - Part I
After the last big quadcopter crash I have decided to start a new project instead trying to fix the current quad. I have been flying this FY450 with the same setup for almost a year now, and I had several crashes and other failures that makes the quad not able for shooting good video footage at this point.
I´ll try to build this multirotor from scratch, which is also a good way to learn how everything works. I pretend to use a lighter frame, and better motors, rotors and ESCs. I will reuse, from the current quad, the Naza M Lite with the GPS, the ImmersionRC 600mw video Tx with the camera, and the same Futaba R6208SB receiver.

The components
For this new project, and after some research, I have chosen some components that hopefully will help to:
Increase flight time,
Better support of the total weight of the quad plus gimbal, camera, etc.,
Building the frame is easy following the instructions sheet. It looks resistant and well finished.

It is important to level the motor holders, so they are as horizontal as possible.

I´m using now a propeller balancer with magnets, I used to do it in a rudimentary way, but I have to say that this balancer works great.

Size comparison between the frame Tarot Iron Man 650 foldable and the frame Whirlwind FY450. The components on the Iron Man are just for illustrative purposes, I don´t know yet where I am placing them.

Connections
Now it´s time for soldering. As you can see in the following pictures, I have soldered together the ESCs and the Naza BEC positives to the red thick wire. The same process with the negatives. Then cover it with thermoretractable tube. This two main wires will be connected to the main battery. The gimbal and the FPV will be fed from their own batteries as usual.
I think the following way of soldering two or more wires together is pretty good, I have done it just like you can see here:
