Winner of Sparkfun AVC now selling homebrew autopilot

Antonio Liska, who has won the Sparkfun AVC for two years with a homebuilt autopilot, is now selling a commercial version of that hardware.  It's called the "Goose" and it's just airplane-only at the moment and closed source, but it has impressive…

Configure 6 flight modes for Futaba T7CP

I bought a cheap RC Futaba T7CP on ebay, but I spent 3 days in order to understand the right configurations of switches to enable 6 flight modes.

Here, my solution. Hope useful for the community.

(I used some hints from other blogs)

1. I used SWE and SWA. SWE is a 3-position switch. while SWA is on the left and it is a 2-position switch

2. You have to set End Point, SubTrim and RT in MIX. First, set the ENDPOINT for CH5 to be 50%(UP) and 52%(DOWN). You can tune…

Inverted flight patch for APM

I thought it would be fun to have an 'inverted flight' switch on my transmitter. With an APM, it's easy! I just added a check for a PWM value above 1700 on channel 7 in read_control_switch(), and when it is above 1700 it sets a inverted_flight boolean. That adds 180 degrees to the nav_roll, which is the target roll for the stabiliser, and it switches the…

FunCub equipped with camera tracking a moving target

Hi all,


I did a flight with Ben Levitt's code to track a moving target with a UavDevBoard.


Here is the video


Many thanks to Ben for the code and to all the core team (Bill Premerlani, Pete Hollands, Ben Levitt), for continuous support.


Best regards,

Modular Test Platform Maiden Flight



This week I took the Modular Test Platform (MTP) for it's maiden flight, I can't tell you how nervous I was to give it it's first throw, or how excited I was when I saw flying through the air! You all probably know what I mean.


I got 2 or 3 "OK" flights in (20-30 seconds) before it had gotten beaten up enough to not really fly anymore. With each crash though, I was expecting more damage, but those wooden dowels really add a lot of strength…

ArduCopter dev team test report and status

Jason, Gigio and I just got back from a day of test flying four ArduCopters, which is the most we've ever had out at one time. These were of different designs, with different props, motors, ESCs, batteries, frames etc. The point was to try to see why some people have great-performing ArduCopters and others have issues. We…

Since getting video into a computer is cheaper than ever, we've been

contemplating the idea of a cheap, turret mounted camera for position

tracking.  The sonar transducer is a huge source of weight & it doesn't

look like Marcy 1 will ever be stable enough to stay in sonar range.

Howto: ArduPilotMega + USB + qGroundControl

This document describes how to connect an ArduPilotMega with qGroundControl via USB (helpful for first tests of your micro controller).



ArduPilotMega is an Arduino based Autopilot micro controller, programmable with C/C++. Arduino based stuff is nice, because it does not require much of hardware knowledge to get started.…

The "Flying Ball"!

This flying ball is invented by Sato Humiyuki and developed by the Japanese TRDI. It is very stable and robust. It has a single propeller and downstream control vanes. Maybe it cannot do advanced aerobatics like a quad but it is very simple and could be better at most applications, especially in urban environment or indoors.

Introducing a new APM feature: real-time Guided Mode

One of the most commonly-used features in pro UAVs is point-and-click mission control in real time. Rather than just pre-planned missions or manually flying the UAV, operators can just click on a map and say "go here now". 


Good news: we've now implemented this in APM. If you update to the latest Mission…

Roll Stabilization for Vertical Photo Mapping

I completed a first test flight for roll stabilization for vertical mapping. It dramatically helps aiming the camera down, and should help with optimizing/maximizing line spacing and acheiving better results for any stitching and photogrammetry processing by getting generally vertical rather than slightly oblique photos.

I used for building the mount itself, this is really handy stuff for these types of projects, it is the tiny version of T slot tubing. Once you use it for…
