Pteryx UAV and PIX4D: one flight, one hour, 4.5km2, only 4 days to make maps

Hi all,

looks that with the spread of processing methods and technology,

we can make things that were available only to national security agencies, once upon a time.

Take a look at the maps of the flight made May 18th:

one day to fly, one day to upload, one day for processing, (one day for grill party), one day to download.…

FAA postpones NPRM to Novemeber!

The FAA has postopned the sUAS NPRM to the end of the year. I am betting this will raise the hackles of both sides of Congress to come down heavy on the FAA in the FAA Reauthorization Act that is currently in conference committee.

Documentation here:…

Quick&Dirty 2-servo aileron "flaperon" support for Ardupilot mega

I recently received my Ardupilot mega, but I could not find instructions on how to get it working on airframes like Twinstar, which have separate servos for each aileron. One related blog post here in diydrones mentioned, that feature is being implemented (although I did not find an open issue about it) but I was too…

Flight testing - Well, learning to fly

Since my last post here, I've been patiently waiting for HobbyKing to get more Turingy 9x radio systems in stock. Alas, they sold out of Mode 2 before I could get an order together with a friend at work, so I went for a mode 1 when he placed his order and laid plans to break out the tools and change things over.…

Who should be a beta tester?

We love our beta testers. They help us find bugs, fix them and test all those variations of hardware and configuration that no single dev team could test themselves. Much of the sucess of APM, ArduCopter and all the other DIY Drones projects is due to a large and incredibly supportive group of beta testers.

AMA identifies manufacturer demos of model aircraft as Commercial use.

The AMA insurance liason, Ilona Maine, has identified model aircraft used in manufacturer demos and sponsored pilots to be commercial uses and not covered by AMA insurance.


"You asked if a noon-time flight demo for the purposes of promoting the future sales of a RC product constitutes a "commercial…

Mode Switch Setup for Turnigy 9x


Mode switch setup for Turnigy 9x

First thanks to tiger in the ardupirates thread at RC Groups who not only supplied me the files to reflash my radio back to standard, but included a model in the eeprom file with the mixes already setup. I just had to tweak the numbers a little and write a…

BOLT: Very small, fast + agile Y6 hexacopter

Once in a while a need a new copter, this time it had to be a very small Y6 copter. It is meant for FPV flying, and that really works very good! It fits through really small holes, and it flies very precisely. It is my first Y6, and I am pretty much convinced by this concept. Ok, well, flight time is an issue.. I get 6:30 min with 1000mAh,…

AC2 2.0.6 Beta

Just letting you all know that a new version is up. You must use the new version of Michael's Tool to do the setup. The older tool won't work with this version. CLI usage through the Arduino serial window will always work.


Many bugs are squashed. PID reports correctly now for D terms. 

The new rate based nav is on by default, but please be careful with it. Keep that hand on the Mode switch! 

Frames are a compile time option in the AP_Config.h file. (or use the…

Excitng First ArduCopter Mega Mission!

I finally got up the courage to try a mission with 2.05. I set up a very simple mission - takoff to 10 meters, loiter time 60, land. All the coords were very close to each other so it should land about where it took off. The first two times I started the mission, it went up a few feet and then bounced around the ground like it was at altitude and loitering. The third time was very different - Up it went very high - seemed like more like 100' rather than 10 meters - and I was sweating bullets.… Continue

Ground Locomotion: Crawling Quadrotors and MultiCopters


One area of multi-rotor UAV research that has been barely scratched is ground locomotion. The definition of ground locomotion is the use of systems built into the flight vehicle to move on the ground, likely without using the flight propulsive systems. Basically, this is what you get when you combine a…

New Commercial Quad-Copter Available

TiaLinx has announced the launch of the Phoenix50-H. The quad coaxial mini-copter system is capable of performing multiple functions such as detecting movement or breathing of a hiding person in a compound from a sloped roof. The mini-copter can be remotely controlled at extended standoff distances of more than multiples of 100 feet from ground or an airborne asset to keep the operators out of harm's way.

The lightweight and agile mini-copter with… Continue

Camera tracking, stabilisation, triggering and waypoint activity updated to APM2.1

Hi guys this is another late night post but I'll try to lay it out right.

I have updated the:

  • Camera tracking code to use the new DCM maths
  • Camera control code to use the APM_RC stuff instead of the outdated servo_out (ashame to be honest as that was very easy to use but the new one is more…

ArdupilotMegaPlanner runs natively on ubuntu linux with the program mono

ArdupilotMegaPlanner was written in .net which is a Microsoft language that they opened up the standards to. An opensource mutiplatform version of .net's CLR came out called mono. Ubuntu comes with mono installed so you can run ArdupilotMegaPlanner.exe without installing anything. All you have to do is open…
