I have a T-Rex 450 in standard (Pod & Boom) trim, as well as a couple of clones in dress trim (Augusta 109 and Bell MD500D), a couple of T-Rex 250's (1 Pod & Boom, the other in a Airwolf fuselage), a couple of Gaui 200 Flybarless, and a Gaui 550 (all of them in Pod & Boom config).

As for ground vehicles, I have a few 10th scale road cars (Yokomo, HPI, X-Ray), and a drifter (HPI). 

A while ago, I got really heavily into the Kyosho Mini-Z thing, and I think I have about 6-7 running Mini-Z (F-1, AWD, 2WD), as well as over 50 collectable Mini-Z bodies.

It wasn't until earlier this year that I realized the goal of designing, building, and flying a multi made entirely from 3D printed parts made on the SD3, this is what version 1 looked like...

Since then the alloy tube arms have been replaced with carbon fiber and many of the pieces have been refined so it now looks more like a commercially available frame than the prototype did.

Prior to that my first complete 3D frame was a copy of one I had bought, done mainly to see if it was practical to make and if it could hold up as well as a frame made from other materials...

Both of these are setup primarily for FPV and I use them regularly. I fly mainly at an AMA club field that is RC Heli only and multirotor friendly, it helps that the club VP is the owner of the LHS and also into multis as well as I'm on the club steering committee.

Lately I've been getting a lot of side work from a couple companies doing multirotor design and build for commercial applications, they like the fact that I know the multirotor side of things along with having the 3D design and print capability. It has actually now gotten close to being a second full time job and I've made enough $ to finance buying 2 new printers to keep up with the demand!

Won't be quitting my day job anytime soon but it's nice to have some extra $ coming in to finance my addictions

Then I bought a full size quadcopter 450 that I modified with an aluminium custom plates set, and very soon after a FPVDM Tricopter, which is since then totaly rebuilt.

I'm flying with multiwii crius, Open pilot CC (probably my favorite) and a KK2.1 board for my test frames.

All of them now have 3D printed parts !! I even printed a famous quad that you can find on thingiverse, it's the SPYDA 500.

I basically got the 3D printer as an investment to keep my hobby expenses low, and as well not waiting like 3 weeks to get the stuff from china !!

I'll post some pirctures on here when I'll be home. But yes, those things are very addictive !!

I'm very happy to see some very serious flyers on soliforum !! I'm an amateur when I see you guys machines!!

In your original post, your second picture, i can see the rotors, but there are two additional arms sticking out to the side with bits on the ends.... What are these?

It is the little brother of the mQx Boz posted. $100 with controller included. Flies beautifully out of the box with low and low rates, as well as a self stabilising mode (which can be turned off if you are adventurous).

Equivalent replacement batteries are only $5, so I have six to keep it in the air for a long time.

Best part for me is that I've found replacement parts for cheap. eg. motors and props from crazyflie are compatible and half the price of the blade factory replacements.

I'm fairly new to quadcopters, but I have a Syma X1 and it is a pretty good beginners quad.  The price hovers around $30-35 on amazon, but I've seen it go as low as $26.  It's still in the "toy" range of quadcopters and not nearly near the hobby grade, but it is a good way to get acclimated to flying one and it is nearly indestructible in my experience.

My brother bought a MQX quad before I got mine, and it retails for around $150.  It flies a little different, but it's almost exactly the same size as the Syma.  I honestly prefer my Syma, but it is another option.

Great photos !!! what did you used to make those pics ?

Thats with our prototype pre-release Phantom 2 Vision from DJI.
