Arducopter with Xaircraft X650 value frame


I've been looking around for a cool frame and came across the X650 V4 frame from Xaircraft.

Before I ordered it from BDpowers I did some homework concerning were I would put all the hardware.

The frame has space for the ESC's just next to the motors so I wanted to be certain that my ESC's would fit. I managed to putin them in the tight space but using the X650 ESC covers wasn't possible. Putteing the ESC's under the props keep them very cool. Also the distance between motor and ESC is kept to aminimum. EMI from powerlines will also be reduced this way. I also looked at the center plate that would hold the APM and IMU. It fits nicely and all connectors are accessable. The folding arms of this frame was a bonus.


The current setup are :

KDA 20-22L

APC 10x4.7

Plush 30 A

Motor to motor is 60cm


Currently I'm doing tests with the latest v49 code and the first couple of flight (excl gps and sonar) were very promising.


I would like to upgrade to avroto motors 2814 and perhaps a bigger 11" prop.


Suggestions welcome.

  • Thank you for your answer.

    I purchased this model XA-X650V4-FRM_PU - V4 XAircraftX650 Quad Copter Kit with Power Unit Frame
    . I'm doing the same as you but with the motors and esc's XAircraft .. share data and photos soon.

  • If I understand correctly, I only bought the frame without motors and ESC's, so no testing was possible.

  • A question I am about the same but receives a frame with motor and esc. have tested the motor and esc XAircraft?

  • The BTS555 is something on the wishlist. Thanks for the advice.


    Meanwhile I made some G10 plates for mounting the sonar. The sonar is fixed next to the battery mount plate away fromall ESC's and other electronics. I also used an old mouse cableto connect threally helpse sonar. And yes, al the peaks I had earlier are gone. It really helps.


    I also made a fixed Gopro mount andthe first tests showno vibration what so ever.


    The next step I did was using graupner eprops 10x5 instead of the APC's 10x4.7. What I noticed is that the APChave more lift. Throttle is at 55% for hover whilst Eprops need 70%.

    Now I've ordered  4 Tmotors 2814and looking forward to the extra power.

    I'll also be trying somebigger propsto see the difference in lift.



  • And only cut when motors are disarmd
  • Mb interrupter AB to relay of the imu board. So you can give the esc's power on distance :-)
  • Great!!! Thx

  • Oh ok ejeje i see now! :) , hey Vincent I was on a web yesterday and saw this PDB with BTS555 and switch on/off included, may be this image can help! 


  • Ok thx.


    @Ramon, there is only one mag. The blue board under thr sparkfun mag is the diydrones interface.

  • @Vincent


    Its super simple


    pin 3 & Tab --> +V input
    1 & 5 --> +V output
    pin 4 --> Diagnostic feedback(Not used
    pin 2 --> signal input (attach to switch and pull to ground)
