How to Set Up a CC3D Quadcopter for One-step Flips

  I am new to drones and recently tried flips and rolls, and did it successfully with some tutorials help, so just share my experience here. Welcome to discuss and share your ideas here. The accessories links are attached at the end.

  OK, let’s go straight to the point – how to set up the CC3D quadcopter for flips and rolls. Follow my steps, you can get it too. I use a semi self-stabilization, here is how to do

Step 1: Set Mode…

RTK Rover and Base Configuration Web Interface

When I first started to mess around with RTKLIB I've wanted to have a nice UI to do that, while researching it I came across a product from which already has a nice UI and I was glad to find its an open source (!!).…

Tricopter tail boom linkage

Here's a better photo showing the tail boom linkage - basically a pair of printed gears.

This design has fewer parts than a conventional linkage, less things to break so hopefully more reliable.

There's a 2:1 gearing ratio between the servo and the tail boom. The servo moves +/- 60…

ArduPilot, PX4 dominate AUVSI drone competition

When we got started ten years ago, the annual AUVSI student drone competition was dominated by commercial autopilots, such as Piccolo. Now it's almost entirely open source autopilots, led by ArduPilot (14 of top 20) and Dronecode/PX4 (3 of top twenty). I'm super proud of this having co-founded…

Tricopter assembly

Dry assembly to make sure all parts fit, so far so good.

The distance between motors is 450mm so obviously the arms need to be cut down.

A PixFalcon goes on top, the GPS/Compass module will either go directly on top of the PixFalcon or have its own mount at the front of the drone.

Target weight…

Quadcopter ESC: Type, Firmware and Key parameters

Before choosing the best esc for quadcopter or FPV, you should know some ESC knowledges (Type, Firmware and Key parameters) as below.

ESC type

A Brushed Motor has a rotating set of wound wire coils which acts as an electromagnet with two poles.

A Brushless Motor uses a permanent…

Printing almost complete 13 hours later.

Not sure about the 'lurid purple' colour, for some reason it was the only filament left at the shop.

This version doesn't have a camera gimbal, I want to see what the all up weight is without any 'extras' and have some fun flying it…

How to make a carbon fiber core balsa panel - tutorial - DIY

For RC/UAV uses, a balsa core laminated with carbon fiber makes an ultra light construction panel with very high stiffness. While you can buy ready made panels (usually expensive), this video shows how easily you can make it yourself with no special tools.

This video does not pretend to show the best way of doing these panels. It is…

Comparing Precision of Autopilots for Survey Missions - Pixhawk with ArduCopter firmware


We have reached the long-awaited episode in our autopilot precision series in which we finally test Pixhawk. All drones are tested by flying them on a simple photogrammetry route created in UgCS mission planning software. In this video Pixhawk was mounted on 3DR IRIS platform, the same…

Drone Pilots Are Buying Russian Software to Hack Their Way Past DJI's No Fly Zones

Should drone owners be able to fly their drones wherever and however they want to? This is the question increasingly asked by the consumer drone community as drone giant DJI tightens flying restrictions on its customers.

This was the…

Getting down to target weight has been challenging.

This version is lighter, stronger, and stiffer than its predecessors. Only airtime and hard landings will show if its good enough.

I'm printing in PLA with 60% infill, 0.2mm layers and slow print speeds which seems to give the strongest parts.

I'll post photos when its…

Aeromapper Talon demonstrates BVLOS capabilities by flying 30Km away from operators

This time an Aeromapper Talon flew a mission autonomously to a target located 30km away from the operators, while maintaining at all times a strong communications and control link. This demonstrates the great potential for Beyond Visual Line of Sight operations for applications such as power line…

Phantom 4 vs dji Spark

Just a comparison video for the benefit of anyone curious.

on a side note, it is strange that DJI has decided to make you connect to the controller via wifi (and has decided to use a stunted mavic controller), i found that you could connect via cable to the dji application via USB because my wifi…

3 difference flight controller types of flying style

quadcopter Flight controller Flight controllers tend to be aimed at different types of flying style: Cinema Flying, Sport Flying and Autonomous Flying. At the same time, there is a massive number of flight controller brands in the market, so it's hard to know which is best. Today I will give some perspective on that.

Intel cancels Edison, Joule boards

It was well known that Edison was going to be discontinued this year, but Joule, which was just released, is a surprise. This is bad news for any autopilot board that uses Edison, such as Pixhawk 2.1, which will now have to move to another companion computer. (I'd suggest Raspberry Pi). From …
