A tray for the battery was added. Keeping simplicity and light weight in mind, I have built this tray based on an aluminium foil and four threaded rods. Four plastic straws (from kids balloons) served as spacers between the tray and the quadcopter chassis. The height of the tray was set based on the Turnigy 5000 mAh 3S battery I will be using:

New quadcopter taking shape
One evening at a time and this new drone begins to get closer to completion. Motors installed and thread locked. Power distribution board and flight controller also installed. The next step will be to install the reprogrammed ESCs (I will check for SimonK updates), wire things together, and make a support for the battery (I'm thinking about using some folded threaded rods as a kind of cage for holding it, or something similar).

New drone, old parts
With all the changes and upgrades I performed on my current quadcopter, I realized I had about enough spare parts to build another one. The only missing thing was the frame, but this is where the fun part goes. With this I had the opportunity to build a frame from scratch after buying 1m of aluminum rod, and a 1.5 mm sheet of the same material. This resulted in a 177 gr frame, which is not too bad.

Ground Control Station
With the model aircraft hobby scaling beyond line of sight, control equipment also grows more complex and sophisticated these days. To the point where we no longer designate it of transmitter, but refer to it as "Ground Control Station".

Powerwheels RC conversion
I soon noticed my 20 month daughter affinity to vehicles. I wanted to give her one where she could sit and enjoy the ride, but currently most powered vehicles for infants require they are able to reach the throttle pedal and properly handle the steering wheel. So I figured out the best way would be to go remote controlled. As I already had done previous projects involving RC gear, it would be piece of cake to turn a regular electric car into a large scale RC car where a small kid could sit inside.

Power Supply Refactoring - finishing the details
In spite of already being a working device, there were aspects that like I explained in the previous post, required some attention. One of the major fixes was the voltage drift. This was caused by the 5 K potentiometer used to set the voltage end point. It was too large (the sweet spot of my setup was around 500 Ohms), which besides making it difficult to adjust, caused temperature induced resistance drift to be too large, causing an increase of around 200 mV from the initial voltage once the temperature settled.

Power Supply Refactoring - closing the hood
After many hours of work I finally can say it's done. Even though I don't consider it the perfect work, I can definitively consider it a major improvement in respect to the previous version of the PSU:
