Hi DIY guys, I would like to show you my almost finished Tarot FY680 setup.


3689547833?profile=originalI saw different approaches for ESC mounting. I choose bottom because a couple of reasons:

1-My motors wires were long enough to reach central frame, they came with 3.5mm male gold connectors.
2-I like ESC free arms, and I don't think hot dissipation will be an issue for this setup. 


So the frame remains being foldable even with ESC out of the arms. 

I decided not to use standard payload bars to fix my ASP Brushless Gimbal. Instead I 3D printed 4 plastic adapters to fix gimbal using M3 screws and Tarot originals plate holes.

Flight controller mount was more easier I printed out a case from Thingiverse.com APM 2.5 Case. I just made some changes to fit horizontal pin out. 


Landing gear was a more complicated. I took 2 standard electric landing gears for planes and replace the rotary plastic piece for a custom 3D printed. Also I printed out a wrapper in order to fix the leg to the fixed middle arm. 



The leg is wrapped by another 3D printed part which is the weakest part of the assembly so I'm working in different way to handle the leg without exposing an-isotropic weaknesses of ABS FDM printed parts. 

System looks weak for rude landings, but It handles vertical hard landings easily. I didn't try yet landings with horizontal velocity or over irregular ground, and I wont. It works well considering it only cost $ 70 while a prof. solution can cost more than $ 800. Now I'm waiting for a new 3-axis gimbal.

Some tests here:

GPS and radio goes to a pretty case which I made my self. You can get it from http://www.thingiverse.com/thing:148552

This case was meant to hold CRIUS GPS module not a 3DR GPS. If you have a 3DR take a look to this one http://www.thingiverse.com/thing:91847.


Motors HP2814 - 810kv

Props Carbon fiber 13x6.5

APM 2.5



3DR 433Mhz radio.

  • I'm just working on a way to fix these retracts to my tarot 680 and found this post. Can you share the bracket for attaching them to the arms? would save me a lot of time thanks :-)

  • yes.. I like that plastic adapters to mount RC Timer gimble... where can I get one.. I just brought my gimble and try to mount it on Tarot 680

  • Where can I buy these items?

  • Hi, can you also give us the files (3D printer) for the landing gear parts?

  • Hi ! Really nice Landing gear 

  • +1
  • Great job on the retracts!  I have been looking for an example of someone doing this, as the commercially available ones for the S800 or others are ridiculously overpriced!  Now all I need to do is order a 3d printer!! :)  

    Thanks for posting!


  • Thanks so much.  I'd be interested in trying to print these parts on my solidoodle as well.  are the files available anywhere?

  • I believe the retracts are worm drive, so if they don't actually lock up (and I bet they do), then they still wouldn't require much power.

    I really like these Tarot frames.  Great value for money. 

  • Nice landing gear hack.

    Any idea how much power the retract servos consume during flight (i.e., when the legs are up)?

    Would you be willing to share the CAD files for those parts?
