In true DIY form I am using as much readily available material as possible. 3/4" oak frame, lego parts, etc. I am on the lookout for landing gear materials (small diameter PVC with small caster wheels maybe? Hmmm.).



I am still building and tuning, so please excuse the loose wiring. When I am done tuning, I will neaten things up. Notice the flanker lego pads for future expansion and additonal equipment (FPV).



This is a picture of the "undercarriage" where the lego battery holder is located. Everything to this point is glued and screwed.



Lego battery connector epoxied to battery.



The lego battery holder base is epoxied and screwed to the frame. I have not only epoxied the lego battery connector to the battery but I will also zip tie the battery to the lego battery holder base for redundancy.



Voltage alarm "legoed" to frame. Receiver is also "legoed" to frame below the KK2 board and power distribution board both of which are secured to lego base with nylon screws.


I hope to be done tuning this weekend. Please watch for the maiden voyage coming soon on video.

  • Love the use of lego!! Looks great!

  • Sorry for the delay. While I was at the post office, returning some junk that I bought from Hobby King, I had them weigh the Quad (fully equipped: Battery, Canon Powershot A4000IS,etc.) = 4 lbs - 9 oz. A lot heavier than I estimated.

  • I WON'T FORGET THE HEATSHRINK. . . Thanks all!

    these little balls (like mini whiffle balls... for golf?) have been working well for me.  They're light and don't snag in the grass.


  • +1 Tom. I have never understood the obsession with carbon fiber. It is great stuff but unless the specifications for the project call for that material and its modulus, why use it?

    Build on Acorn (and don't forget the heatshrink...)!


  • I think this is the first oak frame I have seen. You might be surprised at how flight characteristics change on a lighter, pine frame. I have evolved from carbon fiber (brittle like glass) to pine & thin ply. I get lighter frames, less breakage, and faster repair.

    R.DStar +1  , I was just going to say heat shrink.;-)

  • Don't forget the heatshrink on those motor leads... and all those other leads where the wires are soldered into connectors.

    It is looking great!


  • "I'm learning + having fun" = Recipe for Success, in my experience.

  • I'm sure it will fly really well since the the build looks true and straight. You can always mess around with weight reduction in order to increase your flight times but as long as it's balanced, tuned and has sufficient power it should fly well.
