Innovative solution for RC hobby

Autopilot by Zbig & Pitlab

RTH Autopilot is safety part of FPV system. It offer IMU based stabilization of the plane in hard conditions, flight through the waypoints and automatic return to home in case of RC link lost.  Autopilot offer 3 flying modes activated with free RC channel:

  • Transparent mode (OFF), where signals from RC are redirected to servos
  • Stabilization mode (STAB), where flight is automatically stabilized. User using his RC set desired angles of pitch and roll ordering to the autopilot to keep them
  • Autonomous mode (AUTO), where autopilot continue flight to the next waypoints without user input.

It offer also some sub modes like:

  • TAKE – a sub mode of STAB with additional climbing support for fast, controlled takeoffs.
  • Land - a sub mode of AUTO, the autopilot controls an Auto Landing,
  • Hold - a sub mode of AUTO, the autopilot controls Auto altitude and course Hold (for 5 km),
  • Wp X - a sub mode of AUTO, the autopilot controls flight to Waypoints,
  • Route - a sub mode of AUTO, the autopilot controls flight through a Route,
  • Base - a sub mode of AUTO, the autopilot controls Auto RTH - Return to home (base or starting point),
  • RWxxx - a sub mode of AUTO, the autopilot controls Auto flight to RTR - Return to runway,
  • (*) - a sub mode of AUTO, the autopilot performs an AUTO Circle at a given GPS point.

Autopilot offer many mixers to allow wide choice of flying platform. Actually it support settings:

  • Classic T
  • Ailerons on 1 or 2 channels
  • Flying wing
  • V-tail or reversed V-tail
  • Reverse on aileron, elevator and rudder

FPV Autopilot is configured from OSD with on screen menu. Configuration can be done also in flight. Autopilot can't work without OSD. For fully autonomous autopilot see Dedalus Autopilot.



FPV Autopilot with OSD


Autopilot connectors

The Autopilot board is mounted over OSD using poliamide spacers. Some of the connectors like GPS and RC  are connected together between FPV Autopilot and OSD boards. When you upgrading your OSD with FPV Autopilot, please switch the GPS socket from OSD to blue Autopilot connector. Also RC channel used to configuring OSD can be plugged into right angle 3 pin servo connector called OSD mode.

RTH autopilot connection

Meaning of the connectors and signals on RTH Autopilot.



The FPV Autopilot get power from BEC or battery connected to any servo connectors. Voltage of servo power source should be in range from 4.8V to 8.3V for high voltage servo. Selecting the BEC to the model current consumption keep in mind the autopilot controls model much better then human but use servos more frequently and consume more current.

Servos and RC channel inputs has common power bus, so RC receiver can be powered from Autopilot without any additional power sources or connections.

My short answer is, go ahead and order, you will be 110% satisfied with your stated requirement

I've used most non-"open source" FCs over the last five years or so and none compare to the Pitlab. It just simply works right out of the box.

Just wanted to say that i am very impressed with the pitlab osd+ap. Usually i only speak if there are problems. But i recommend pitlab to all of my friends. Its an amazing system. Thanks guys !
