Channel Reversing Problem - Skyfun

Hi all,

I am configuring my Skyartec Skyfun with APM and Oilpan. I have the system set up so all channels operate correctly in manual flight mode (APM not engaged) but as soon as I switch to stabilise or FBW, although the APM responds correctly in te

configurator keeps disconnecting

I only have the APM and the IMU shield, but I was wanting to test it out using the configurator. I keep having a problem with the configurator not wanting to connect to the board. I do have it in debug mode for the gyro.  Does that keep it from conne

X Configuration Observation

Hi,

I have just built a quadcopter in an X configuration. I have been having majorproblems (stability, twitchy, uncontrollable ...) trying to get it to take offon its 1st flight. So I thought I would try tuning the PID using theconfigurator software.

1st Flight strategy

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

Arducopter Lights and Leds

I was wondering if it is possible to have the onboard lights  behavior copied to some led’s connected somewhere in available outputs , for tows ho have a closed body’s for they cuadcopters .

And where are the navigational lights connected in the curre

Moisture sensitive devices? True or not?

Hi all,

I ordered some ADXL345, HMC5843 and ITG-3200 .. all off them are marked as moisture sensitive devices. On the specs they say that they can get damaged after opening the moisture protective bag.. They say that once opened they would have a life

Ublox U-center data through APM

Hello.

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.

Heavy-Fuel Engines for UAVs

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

funjet build log?

I see you have the funjet on the front page.. Is there a build log or something like that for makeing it a drone :) I guess some one has the parameters and stuff :)

Sony bloggie for Real-time FPV (Please help if you did this!)

I am looking for someone who has used the Sony bloggie for FPV on their Quads. I have the MHS-PM5 camera but I am wondering what modifications and other components are needed for this to work. Any and all information would be appreciated!

ublox mod (no more lost GPS or Antenna!)

Here is a simple mod I did to my ublox GPS. The hot glue was not keeping the boards together and the cap to the antenna was loose and probably would have come off first flight. I just took a piece of clear shrink tube and placed it over the boards an

Removing GPS altitude and velocity limits

Hello all,

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

Why Quadrotor

What are the differences among using single engine, twin engine, three engine helicopters, and quadrotor? I mean what are the differences in flight characteristics?

Is anyone doing wireless telemetry here? What are you using?

I posted this in the wireless section but no response so thought better to post it here.

Stream.h missing?

Hello everyone,

ArduIMU V2 Flat does not communicate after initial success

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

xbee - definitive set-up

Just wondered whether anyone can recommend a definitive xbee set-up (modules and adaptors) - one which is know to work with as little fuss as possible?
