The quad frame is very nice. The assembly is realy easy, but you should have a look at the file section here. There you can find some pictures of assembled frames. There seems to be no assembly manual. I have used it to create a transportable quad frame. Realy cool foldable function. The frame has a landing gear with spring shock absorbers, but those are realy hard.
Using this frame with some 2212/920kv Motors, 1050 props and a kk mini 2.1 fc. Nice setup so far.

I bought this to use it for spare parts for a kit I built and fly. The original kit was pretty abused until a KK 2.1.5 flight controller was installed and programmed. You can break motor mounts if the props hit the ground, the idea of using two mounts for strength sounds good. There is also a problem with the legs breaking motor wires if you land too hard, I rounded off the ends of the legs so they cannot protrude above the frame on hard landings. I didn't see much upwards bending of the arms until a heavier 5Ah battery was installed. It's not the arms that bend but the fiberglass inner frame they attach too. If I were starting over learning to fly I would mount a nice big piece of foam under the battery to reduce landing shock. Next time a 4 in 1 ESC will be used to minimize the number of tie wraps required. Make sure to balance your props well and if you can see motor shaft between the hub and the top of the motor shorten the shaft. That gap just creates a lever arm for any prop imbalance. For the price this frame can't be beat, buy two so you have spares.

Excellent 'no-nonsense' frame, light and strong. The spring-loaded landing 'claws' are a nice feature, they look fierce and actually help cushion any bad landing. My kit was complete, no missing hardware.
Two tips: slide the springs on the axles before assembling the two halves and don't tighten the screws too much or you will bend the arms. Also, keep in mind that the motors on this frame are close to the ground so on take-off you need to promptly 'jump' to avoid ground effect turbulence which could push your quad all over the place. When it is at least 50cm high, it will be much more stable.
There is enough space under the quad for a 4S 5000mah battery and still sufficient ground clearance during landing.

Cheap! So I ordered 2 for spare parts. Not really a beginner quad. It's large, and doesn't take light crashes well.

Excellent frame, unbeatable for the money. I especially like the suspended 'claw-like' landing gear. Recommended 8" or 9" props look too small for this size of quad but you can fit 10" props (with a low KV motor). This frame is rather large so the bigger props fit easily.

As mentioned in the previous reviews, I bought 2 of these inexpensive frames and it was great advice. Being new to the quadcopter game I've had a few crashes and the spare frame has served well. Surprisingly I have not broken or bent any arms or the center of the frame, it's only been motor mounts and landing legs. I have had some big crashes too. This frame holds up well to hard landings. The only down side is the arms can move as its foldable and it can induce drift when the arm moves out of alignment after a hard landing. Still an excellent frame to begin with, It has exceeded my expectations.

not bad frame, had to do some mods, the folding of the arms is a bad design, I had to mount the bottom body plate so that you could not fold the arms

One of the strongest frame that I have ever seen, the best one so far. The frame is not heavy compared to its size, using a 390Kv multistar motor, i get nearly 20 mins of flight time

Body was easy to assemble once I found the instructions in the file tab. Seems fairly durable. Should make a fun quad body. I am running 10 inch props, but you could probably run up to 12 inch props and be fine.
