DeltaQuad VTOL autonomous maiden flight

After some succes with the QuadRanger we developed we decided to step it up and convert this Skywalker X8 to VTOL. And this was it's maiden (autonomous) flight

It was outfitted with the PX4 flightstack too which I recently added the VTOL_TAKEOFF and VTOL_LAND support.

The maiden flight of the DeltaQuad was a succes. It slightly overshot it's landing site due to a miscalibration of the airspeed sensor (it was flying faster then measured). Still it made for a very smooth flight.

In the next few weeks we will start payload and endurance testing, based on the current data it looks like it could carry a 1-2 kg payload for a distance of around 80km.

The build serves as a prototype for the modules/platforms that we (DronesLab) aim to produce and make available this year. 

I'm very interested in your thoughts, idea's and comments so feel free to drop a line!

    Hey Thomas,

    DronesLab is in it's startup phase and will launch soon. DronesLab aims to develop industrial drone solutions and platforms. vdrones.com will be the 'outlet' where some platforms will be made available for consumers. Currently all platforms in development are VTOL, (hence Vdrones)

    An introduction to DronesLab and Vdrones will follow as soon as we stabilize production and have the first platforms out of R&D.

  • Hi Sander,

    can you introduce your DronesLab to us? or you can post the link to follow .

    Thanks for liking my post, i removed your comment as it contained spam.

    @nick i see the FX wings only use one carbon spar, that will not be enough to get a stable quad mounted. If you go on that route you should consider adding another spar

    This build is different from the QuadRanger. The arms are made from 20mm square carbon tubes that mount over the round carbon tubes, they need to be angled out using some heavy industrial methods to keep them strong. This way the wings are still easily removable.

    The modules for production will most likely contain an extension piece to the wing to remove the need to angle the tubes out. If there is more clearance from the pusher prop on the FX-61 this would probably be an easy build. just follow the quadranger build for the motor mounts and drill holes that match the round carbon spars.

    A home built version would probably be easy to do using the QuadRanger method, or wait until we put these modules in production and order them plug&play :)

  • Cool.

    @Nick FX-61 +1 :)

    Can you share a detail how quad arms are fixed? 

  • hello sander

    very cool!

    can you an explain your  setup? (its the same as the quadranger or different ?)

    motor ( kv ) propellers esc etc and mounting it' ll be very nice

    i have the X8 at home  and i'll want to convert it!

    and so cool again good job

  • Cool

  • Very cool! I'm also thinking about making one for novelty, perhaps with a FX-79 or smaller FX-61

  • Nice job ! Transition is so smooth, impressive.

    I am very tempted to try with the old X8 hanging in my workshop.
