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.

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.
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.
Dany - I'm hoping the use of legos provides some versitility in adding equipment. I plan to weigh it soon. I will post weight with maiden video.
John - I've found the kk2 board itself easy to learn. However, the whole quad build process has had a steep learning curve overall. I'm learning and having fun. I hope I'm not dissappointed once I get it in the air. . .
Nice use of Lego... but most of use use velcro, you save some weight.
still put a velcro strap around that lipo, you dont want to lose it in the air!
what`s the weight so far?
