I'm a student at Hochschule Bremen and I'm working with matlab/simulinkon these days but I got an error in the simulink model which is about
a strapdown inertial navigation system. The error says "Derivative input 1

As the manual states, I have read and reread the manual and trying to
take things step by step. I have included the ArduPilotMega.Pde file.

Hello everybody !
I am up to do my 1st flight with my quad :
- structure/ESCs/motors from a GAUI 330x, what was flying well.
(I have unmounted its GAUI inertial unit)
- Rx is a Spektrum AR9000 (Tx a Graupner MC22)
- New IMU : APM with its sensor board

I have a Ublox unit from DIYdrones which is connected to my APM, which in turn is connected via USB to my PC.
I've uploaded the following code and GPS information can be seen through the serial monitor.

Has anybody tested those new heavy-fuel engines for UAVs (http://www.3w-international.com/1-cylinder-heavy-fuel-engine/)? I just saw the Aerosonde was flown about 10 days ago with a heavy fuel engine. Would you recommend them? Can you comment about t

Anybody here has experience with trying to remove the export-control velocity and altitude limits from any of the popular GPS receivers? I am thinking U-blox, Mediatek or SiRF. I know these limits can be removed from the high-end units from
What are the differences among using single engine, twin engine, three engine helicopters, and quadrotor? I mean what are the differences in flight characteristics?

Hello everyone,
Two nights ago I unpluged my ArduIMU v2 flat after sa uccessful first time checkout with new FTDI cable, MediaTek GPS, and ArduIMU Test program. I used Arduino IDE to change the GPS configuration. All worked well.
I come back tonight and hook it

I need a help to model an UAV (birotor), I see a Paul Bizard's simulation, it is very interesting but I do not understand it, I know that I must start with x=Cx .Q.S to find the equations of motion but I need to understand next step, so please help m

Hi All:
I need to use the HCM5843 magnetometer in my project urgently. Howver, now in our DIYDrones store, it is out of stock.
I am wondering Can I replace the DIYDrones-HMC5843 with Sparkfun-HMC5843?
It seems that they are the same in te
