QAV250 performance upgrade

Bigger is not always better.

Especially when trying to get off the ground, weight is a serious issue. Sure its nice to have sturdy landing gear and a big battery, but overall it’ll hurt performance. Because of this, I decided to perform a little weight reduction surgery.

Additionally I’ve upgraded my propellers from 5040 triple props  to 6040 triple props. Adding an extra inch to my blades has definitely increased performance drasticially.

All this plus I re-calibrated my ESC’s max thrust to the maximum suggested rating as well as re calibrated my controller endpoints to ensure that I can get the maximum performance out of my hardware if needed.

All said and done, the birds flying like never before!

QAV250 Drone Tutorial

Overview:

This page was created as a place to document this project as it was built. Since the original setup a lot of modifications and optimizations have been made which I try to go over and highlight as best I can in the tutorial. One issue with writing a tutorial like this is that there are just so many components that could be made to work for the project, therefor I go over the concepts of how the setup should be be more than the actual pin out and wiring diagrams. Research and documentation will show you how specific components need be setup. But regardless I’ve been through it all so I can answer most questions about the build, help with those gritty details when you hit them, and help if you hit a dead end and get stuck.

Before we start: A note to all

Before anything. I just want to mention how important planning is before starting any project. The most crucial part of this whole project is power distribution. Almost every powered device on the drone needs to be plugged directly into the battery. When attempting to get every on board device connected to a common power source issues are bound to show up. Please plan out your power connections meticulously and carefully!

Also* this thing is not a toy and can be dangerous in the wrong circumstances (calibrating motors with your face right next to the thing, test flights in public places, etc) Be careful! Please be careful to not hurt yourself or anyone around you!! Be respectful!

Good luck everyone! I hope your first drone brings you as much joy and excitement that mine has brought for me! and hopefully not as much blood!
