Excellent job. My order from the East warehouse arrived super quick. All parts were in the box and the frame was as advertised. Easy assembly. Being in the U.S., the postage was very reasonable. Thanks, HK !

Great frame for the money. Fits a KK2 & PDB quite happily. Quality of the plates surprised me, nice clean milling & edges. The aluminium used on the arms is strong yet light, it does deform when you tighten stuff down but I had to seriously torque stuff before they bent. Only disappointments were the arms came scratched quite a bit, the anodizing is very light and doesn't take much to scratch through it. It was missing the 3x25mm bolts, you get what you pay for though.

Really good frame. Had no issues with it. Motors will mount with only 2 bolts. not a lot of room for FPV or camera stuff. Very stable and stiff. Extra width goes along way for stability in a quad, i would say that counts for a lot more than any carbon props will.

The Red/Black does help with orientation but only up to about 100 yards; after that there isn't enough contrast to really tell the orientation. There weren't any instructions or assembly diagrams so it took a while to figure out what screws went where. They need to put an assembly diagram under the files tab. I assembled with a Q-Brain 25Ax4 ESC, unfortunately the area between the legs was just a few mm too small to fit the ESC so there wasnt really a good place to put it. Sturdy and handles some pretty hefty crashes well.

I got this frame recently and it is awsome!
It's strong and very light and the folding feature is awsome, just make sure you tighten the legs a bit and do about half a turn back so you can slide it but it wont be wiggly and loose.

Do note the guide doesn't tell you to use the washers a hole lot of times despite there being enough for any screw you'd be using so do add them each time!

The manual also overlooked the fact that the metal spacers should be placed on each leg bit so keep that in mind as well!

The KK board can fit exactly on top instead of the glass fiber piece you get so that is nice as well!

I would like to see the camera attachement to be stocked in europe as well though.

This frame is quite good value and I am pleased I chose it for my first quad. Like some others, it is a good idea to insert wood blocks in the ends of the arms to prevent them from being crushed by the mounting and motor bolts. The hardware supplied is good and adequate and includes a battery strap. It needs legs mounted on the main frame for landing as after a while or after a heavy landing the arms tend to bend up and have to be straightened periodically.
In this one I use a KK2.1 FC board and SK3 2830 Turnigy Aerodrive motors with 9x4.7 Turnigy props and 30 Amp Turnigy Plush ESCs. I use 2450 and 2650 35C batteries. It also goes OK with 1800 35C batteries.
I cut some rings off a broom handle to insert on the legs as ' landing wheels' just to give it a little more ground clearance.
It is a steady frame and can go like a rocket if you want it to, but is also very docile when required.
To sum up, I am quite happy with this frame.
