Arkbird Autopilot System w/OSD (GPS/Altitude Hold/Auto-Level)
The Arkbird Autopilot System w/OSD is an all-in-one solution for your FPV model's navigation. This unit is loaded with features such as GPS waypoint flight, "Return to Home" functionality, auto-leveling, altitude hold and much more! It utilizes GPS, barometer and attitude sensors to stabilize/control your model's flight.
Worried about losing control of your FPV model when flying out of sight? With the Arkbird Autopilot System on-board there is no need to worry! The "Return to Home" function can be activated at any time to fly your model back to its take-off position and will be activated automatically in the event that your model flies out of RF range.
The integrated OSD system provides you with all of the information you need during flight such as altitude, flying direction, home direction, roll angle, pitch angle and time since take-off just to name a few. This system also includes a current sensor with pre-installed XT60 power plugs so you can monitor your model's flight battery status via the OSD.
The Arkbird Autopilot System comes with everything you need to setup your FPV model for the ultimate in GPS based Autopilot flight. It features a "plug and play" design meaning there is no soldering or modification required to use. All power plugs and wire connections are pre-installed.
Features: • GPS, barometer and attitude sensors to stabilize/control your model's flight • Integrated OSD functionality • GPS based "Return to Home" functionality • 4 point GPS waypoint flight • "Cruise Flight" mode offering straight and level flight pattern holding • Auto-leveling • Easy to setup and adjust
*Note: See user manual located under the "Files" tab below for full features/specification for this system.
My arkbird osd was working fine with RTH functionality. I face one crash after that the compass is not giving correct direction. I am afraid that if I install it on a plane , will this AP work? Is there any method to ascertain whether the unit is functioning perfectly?
You should be able to test all the functions of the ArkBird AP on the ground... Just let it find enough satellites to determine its position, and do a neutral point calibration (make sure the plane is level). Once it is "ready to fly", you can walk around with the plane in hand while watching the OSD (using goggles or a portable monitor) and observe the control surfaces' reaction to your changing the aircraft's position and or turning the transmitter off to simulate loss of signal. If the throttle safety switch is enabled in the OSD menu, the ArkBird should do (watch the control surfaces) and show (via the OSD) everything it is supposed to do EXCEPT for throttle changes. However, the OSD still shows what the throttle setting WOULD be if the safety switch wasn't enabled or the unit was more than 30 meters from the home position. I tested mine thoroughly on the ground before taking off, an it had no problems if neutral point and GPS were set properly first. As a side note, I read somewhere that there was a firmware bug (math error) that affected some users outside of Europe, which caused the unit to mis-calculate the heading/position. However, this was only a problem in certain geographic areas, and the firmware has probably been updated in newer units. Mine is working fine here in California. Hope this helps! =)
So if the RC connection is lost I won´*t be able to activate channel 5/6 and make it return? Do they refer to the video link with this: "will be activated automatically in the event that your model flies out of RF range" ??
Some RC receivers (look at the OrangeRx R620 or R800X on this as an example, but your choice depends on your gear) have what is known as "failsafe": they let you program a certain configuration that the Rx will adopt in case it looses signal. The Arkbird enters in RTH mode when both channels 5 and 6 are set at above 70%, so I program my failsafe that way. The effect is that you are flying away and when you loose signal (that you will) your rx enters in failsafe mode, and that is what makes the Arkbird take control in RTH mode, not the Arkbird on its own nor the loss of video. At first it is strange, because suddenly your plane begins to make its own decissions and you try to counter it, but then you realize the little home icon, indicating RTH is on, and you thank you have your Arkbird, because not having it would have meant a lost plane. Most of the times you regain control very quickly, but it depends on why you lost it.
I'm actually using channels 6 and 7 for ArkBird RTH and flight mode control on my Turnigy 9x. ...and since that system does not have a failsafe system on the RX (but oddly, the TX does!), I am using two of the Hobby King micro failsafe devices (HK PRODUCT ID: 9052000004) to tell the ArkBird when the radio control signal is lost. Another oddity is that the micro failsafes would not work on channel 5, hance my choice of channels 6 and 7. The ArkBird doesn't care which two channels you use (beyond 1 - 4) for RTH and flight mode.
Right: 6 inputs and 4 outputs. And JCM is right, Arkbird does not really know about channel numbers, but signal inputs - If you have enough channels in your system you can choose which ones to use for flight mode control, but if you only have six you have to forget about flaps or pan-tilt. My tx has 6 ch. (for 2 weeks only now) and channels 5 and 6 are on off, but using a mix I can "create" the three flight modes.
When I say 3 I mean 4: I forgot normal mode. How many floght modes? RTH is a must, level/stabilized mode is highly desirable, and anything else is disposable. Arkbird has these, and the third (4th) is selectable and adds waypoints or fence mode.
I am very grateful for all this input! I am sorry I have to ask yet another question: What is level/stabilized mode? Are not the "gyros" activated all the time? Is there a mode for holding the aircraft circling over its current position?
Gyros are only on ehen you activate them. In normal mode Arkbird just lets the control signal through, and acts only as OSD. Level mode maintains leveled flight. I use RTH to circle above my head after launching or on the way back to change goggles (very near sighted), but I don't know about circling anywhere. There is HOVER mode as one of those custom modes, but I have not tried it, and the manual says it just like balance mode.
The ArkBird AP can be turned "off" so that the plane is totally under manual control. In "Manual Mode", the unit makes no corrections at all. In the flight stabilized mode (called "Balance Mode") the gyros and sensors are used keep the plane flying level. This is a great mode to fly in most of the time. In RTH mode, the plane will return home and do a more or less circle around/over the launch point at the specified altitude, until you either re-take control or the batteries expire. In "Fence Mode" the ArkBird will allow you to maneuver the aircraft freely within the "fence" boundary (the size and shape of which you can define in the menu). Once it leaves the fence boundary, ArkBird changes to RTH mode and brings the plane back towards home until it is again inside the fence, at which time it returns control back to you. There are a number of controls in the OSD menu for setting the altitude, flight modes, and various control parameters to suit the size, speed, and sensitivity of you particular aircraft. So far I have tested manual, Balance, and RTH modes and the AP has worked nicely. For best results, it is very important to set the neutral point properly before flight as this is the primary method the ArkBird uses to determine a level pitch and roll attitudes. Cheers! =)
installed it as rcmanpilot did, on EPP FPV, specs as enumerated by him see images tab

good points for this AP: Cheap Easy to use even for NBs Fully integrated Main desired options required for beginner and advanced FPVer Good introduction to AP world leading to a good usage & understanding for future switch to DIY ARDUpilots... Finally all in all ARKBIRD then later on full ARDUpilot conf finally cost cheaper for a better quality than a FY teck complete system witch can cost easily up to 1000 dol for not a better result, i would say even lower. With Ardu, you get total energy indication, Air speed indication, good to calculate Head/tail wind for maximum range ( avoid low bat on the way back if Head wind...) In my opinion that's is definitely the real best choice to go later for nuts ARDUpilot FPV!! PS: that's more that 1 year I am getting documented on that subject...
Only 4 for overall rating cause no sensor upgrade capability.

producto muy recomendable para fpv y otras modalidades..es un poco lioso porque los cables que van del receptor al autopilot no tienen almenos el color negro en el negativo. pero con cuidado y vigilando mucho no es problema.los cables para la camara i el emisor de video tambien se tiene que mirar las polaridades porque no estan del todo iguales...los cables son un poco cortos y duros..si se tiene un avion pequeño es un coñazo....por lo demas con unos bueno alargos se consigue todo..pero sera dificil no tener que coger el soldador i el estaño.
provado en tres vuelos...el resultado esta muy bien...se enciende la emisora sin ningun tipo de activacion y funciona a la primera..es un poco brusco en la modalidad de autoestabilizacion pero bien, muy bien..en vuelo de vuelta a casa es muy rapido y bastante preciso..un poco desordenado porque cuando esta encima del punto de inicio una vez gira a izquierda otra a derechas y no tiene un patron marcado...una vez gira mas cerca otra vez mas lejos pero el resultado final es muy bueno..si no tienes la altura minima acelera el motor y si pasas de la altura minima baja planeando muy controlado y bien una vez esta a la altura el mismo se va dando gas y quitando...el giro de vuelta a casa es muy brusco pero controlado..de momento estoy muy contento y la verdad con lo que cuesta un avi0n equipado y con todo el fpv solo con recuperarl

parte 2..para entrar en el setup tengo que alerones y cola a un lado los dos..una vez entras con la profundidad arriba y abajo navegas y con alerones a derechas entras en el submenu y cuando esta seleccionado lo que quieres alerones a la izquierda y ya esta..a mi me pasa que cuando entra en setup el motor se enciende..a muy pocas revoluciones pero es recomendable sacar la helice...con las baterias a menos de media carga a veces falla la transicion cuando pones el autopilot..y se para.. pero lo achaco mas al variador que al autopilot...porque cuando esta a media o a tope de carga no falla nunca...tardo muy poco en coger los satelites el gps..
I bought this as my first OSD and autopilot. Not very dificult to install, but it peace a higjh tecnology,and as so you need to know what your are locking for, and the principels of fisics behind it. I supose all devices of this king requiry the same background knoledge. Worked sing the first trial, but testing has not yet been very extensive. It's acording to expectation so far. I have already required suport, and could find with some effort (see ww.rcgroups.com if needed).Support was very quick and client oriented . Like!
