  • Board looks really nice Roberto,

    Does it have installed OTP certificate so it will work with off the shelf Mission Planner?

    Best Regards,


  • So this is a full small sized substitute to Pixhawk? And the mission planner works just fine?

  • Ok i stepped into the Vrbrain 5.1 and pre-ordered a board. This will be a good fit for my Ecks 230mm frame. I will let you guys know how it turnes out when it comes in.

  • Any news about the next vrbrain?
  • HiNoli, maybe a belt drive version is better if you want to use RTL function. Less problems with tailstrike.

  • Hi Roberto,

    >>What kind of Hely are you plan to use with our autopilot ? Do you have experience with other board ?

    I am planning to build one using this helicopter kit:

    HK-550TT 3D Torque-Tube Electric Helicopter Kit

    Probably you should build one helicopter phototype using this kit with VR micro brain 5.1.

    >> Do you have experience with other board ?

    We are using APM 2.6 on fixed wing UAV at the moment.

  • i am more interessing by the vrbrain 5.1,i hope it will be available soon

  • Hi Roberto.
    Please PM me as soon as these are ready for purchase.
