Latest AC2 update

This is to let you know that AC2 beta has been updated based on everyone's feedback. I think we're getting closer to a full release.

Things to concentrate on:

Logging - Logs are the most helpful thing you can post. If you have an issue, please post the log and let me know where to look.

Altitude hold: The Dterm was a bit too aggressive preventing the copter from changing altitudes. It's been lowered by default to 0.03. If you have trouble…

DroneCell and 900Mhz Xbee problems ?....


I had the brilliant idea of building a device that will send GPS location over SMS text messages.

this, after i lost my prototype quad Arducopter last week. it felt not too far, i could hear it, but a few days of searching in the forest gave nothing....


R.I.P. dear copter.

here is the last successful flight, in memory..

Flytron's OpenLRS available now

OpenLRS is a radio control system designed by Flytron in Turkey. For most of us, the name will make clear that this is an open source product. Source code is available for download, you can make improvements or change the code and share these with others.


The OpenLRS M1 is an open source transmitter module that is configurable for any channel (420-450mhz) or any…

TaigaCam and pitch/roll stabilizer

Now camera has pitch and roll stabilizer. In some shots camera looks plane. Camera can tilt 90 degrees to one direction and 45 to other, you can see the limits in sharp turns. It was windy day, 4 - 8 m/s or 14 - 29 km/h or 8 - 16 knots.


Program codes are in…

Double blade disaster



Flew something for the 1st time since the PCS order. She didn't

oscillate, but didn't have enough power.  That design had no coning

angle.  Back to wing designs.

TaigaCam and camera stabilizer, pan test

TaigaCam and Ardupilot tries to look home position all the time. Camera can turn about 100 degrees. In Ardupilot there is no compass, and therefore it calculates flight direction once per second according to gps. That's why camera turns slowly.

This pan-system needs only one line of code to Ardupilot. In plane…

UAV School Project

Here is a quick vid of my final project I'm building in electrical engineering. It's a tricopter UAV with thrust vectoring. As of now I have implemented roll, pitch stabilization, yaw and height are controlled by the aircraft. I just control the x and y movement.

All the control algorithms use fuzzy logic. Why? To be different... and to overcome…

Mode Switch Setup


How to setup the mode switch for APM/AC2

This tutorial was created using the Futaba 12fg, but keep reading and it may give you some ideas on your radio. If you already have your particular radio figured out, write a tute like this and maybe we can get a collection of them added to the APM/AC2 wiki's.

You will need two spare switches, a 2 position and a 3 position to be able to get all six flight modes for the APM/AC2. We are aiming to get pulse widths of 1165,…

Aluminium Arducopter parts - first attempt!

As part of my plane to create a simple, solid Arducopter frame, I have had a number of parts laser cut in 2mm 6082 aluminium from the original Arducopter frame design by the DIYD team.



The parts have come back a little more "bashed up" than I expected, but apparently that's normal, they just…

Futaba toggles

This is just a quickie before I go to bed.

Those with a Futaba 6EX will know the toggle don't always feel right when you are flying a plane well as I use both my extra channels for mode switching I figured enough was enough and put them together. I took off the back and traced the wires back to a PCB point.…

New aerial video platform

This is the latest Flying Multicopter Camera system. It uses the Panasonic HDC-TM900. The arms are on rubber mounts and only move if there is any vibration. The motors are Pulso X2826/12 Kv 760 they have 5mm shafts and are three bearing. They run very smoothly compared to the MK3538's. Three axis of inner… Continue

DCM versus Kalman filter


I notice that attitude estimation is done using the DCM algorithm.
I was wondering if anyone, has tried implementing a Kalman filter for attitude estimation?
The DCM update has a nice intutive feel to it, but i would like to throw in a sound math proof for why it converges. Has anyone worked on this so far?
