For years now we use model aircrafts as a hobby or job, and for many years as aerial platforms for aerial photography and mapping. So after many discussions here and reading, I will begin here an UAV application that I think and prepare from student and I hope that now I have the background to make it happen. The reason I post the project here is because I learned all about model aircraft from aeromodelling.gr and everything I know for autopilots from…Continue
Great Idea for FPV, Onboard Camera and LCD on Transmitter Available in just 82$. The product comes in metal case.Continue

Today I maiden my wooden hobbyking Quadcopter and it went fine!
I have flown rc helicopters quite a bit, but that was a couple of years ago. Then i heard an interview with Chris Anderson on Leo Laportes podcast 'Triangulation' and I was intrigued about the drone part of the hobby.
Me and a friend ordererd two ArduPilots and got into it again.
I've heard some people mention using bluetooth to communicate with microcontrollers as replacement for a serial or USB & FTDI. Recently some small bluetooth serial modules have become available from large electronics retailers and smaller ones that operate on large internet auction websites. They can be purchased now for just a few bucks. The module has all the bluetooth components integrated and takes 3 volt TTL level RS232 signals. It comes in a surface mountable pcb package, however…Continue
Here I want to show you my new autopilot hardware which I worked on the past weeks.
The layout and the connections of the boards are chosen for my own convenience.
So airspeed sensor, receiver input, GPS, LEDs and I2C connections are at the front of the…Continue
Finally I could adjust the settings. As a 3D plane P settings Servo Servo Roll and Pitch were adjusted upward.

Nothing too crazy, just a simple test of my stock Easy Star's performance. The 7.4v 1200mha battery and the 450 Brushed motor kept it in the air at 3/4 throttle for just over 14 minutes. It was a very windy day, with steady winds 5-7mph and a few gusts of over 15mph.
Next episode I'll see how high I can fly it!
The MTP3 is almost done, just waiting on some electronics to come in the mail. Then…
Not that great of video, but you get the idea.
There is a better view at 1:02
Hooray, got to the point where I've got APM set up and in a plane (Hawk Sky). Now I need a bit of help diagnosing a flight problem.
I took off and got some altitude, and then flipped into stabilize mode. As you can see from the video, as soon as I did this, the plane started spiraling down and to the right.
I brought the plane back in and recalibrated gyros, but still couldn't get it to work.

I've final finished setting up the worlds first (to my knowledge, and until proven otherwise) ArduPlane F22 Twin EDF with thrust vectoring, flaps, slats, and retractable undercarriage. It flies using delta wing mixing. With 6S 4000 mah.
Take off weight: 2.0 kg
Max thrust: 2.5 kg
Pre-flight complete, with Manual, Stabilize and FBW modes currently programmed. This should make this aircraft easier to fly. With a huge elevator on the back I might have to reduce…Continue
More goodness from the engineers down the hill from me at UC Berkeley. The quad can see and catch ping pong balls! Life is good if you've got a Vicon motion caption system and an Ascending Technologies quad (ie, a big research budget).
Due to the recent shift from a Subversion to a Git repository, you'll need to use the latest versions of the Mission Planner to ensure that you'll be able to get the latest ArduPlane and ArduCopter firmware. Versions from 1.0.67 up will pull from the correct Git repository.
First flight today in full manual mode with a brief session on stabilization mode. Plane: Slowstick - short wings, spinning 8x8 carbon prop, rudder elevator only.
Autopilot: Ardupilot mounted on stick in box from Bask Aerospace.
Ground Station: APM uploaded lastest firmware and using xbee link for comms to laptop.
Flight Report: Like all good flights it went well until the plane flipped onto its back and then I throttled back and waited for the hard…
