It is a great kit, it comes with all bolts labeled, separated in plastic bags, and the build time is just about 15 minutes.
AMAZING KITI can't recommend this frame as there are no replacement parts available and although the arms are very rigid, they are also brittle and break at motor motor with impact.
Also it has a weird flight characteristic where it wobbles at hover I suspect it has to do with the arm design.
Also where has the 330 frame gone?I like this one better than sk450 and the q450. I bought extra feet but have not broken
any yet. I did break an arm where the carbon fiber reinforcement ends. This flys well
and I am getting 14 or 15 minutes with zippy compact 3300 mah 3s 35c batteries.
You get longer times with 5000 mah batteries but it is sluggish with this much weight.
just installed a Mobius I am going to tryout tomorrow.
A perfect frame in its class.
Price / quality ratio is very good to
I made a flight video with a combination of Naza v2 and I will add to the "videos".Very nice frame but litle bit incompatible with bestseller stuf from HK. I Buy this frame and Hobbyking KK2.1.5 Multi-rotor LCD Flight Control Board and i must make a special mounting adapter from wood (missing some universal mounting holes on top plate) . Quality of frame is very good but legs are totaly bad, problem is you need the legs because they hold bottom of frame. They are very long and fragile. After first bad landing i broke 2 legs. Second problem of this frame is litle space behind upp and botom plate.
SUMAR frame is good and verry nice, but incompatible with universal stuff for quad from HK. You need made some mounting adapters and tune legs with saw :DOverall, a very nice frame. The arm stiffness as mentioned by other reviewers is superb. I agree the center plates should be spaced farther apart, but its not a big deal to me; the space provided between the two is still sufficient for a receiver, naza PMU, the provided PDB and more. The landing gear legs are sort of cheap as would be expected, but replacements are so cheap and available its almost not worth mentioning. Interested to see if the arm dihedral provides a more stable hover or decent over my straight armed F450 clone. Buy it!!This turns out to be a very nice, quick build multi copter. The arms are light and very rigid. The landing gear are light and robust. The kit is well packaged and surprisingly well labeled. The instructions are clear (though assembly is fairly obvious to any modeler). This would be my recommendation for a first multi-copter. It flies well with any current Flight Controller available (KK2.1.5, APM, and MultiWii/DSM2 controllers I have tried personally). It is durable and surprisingly inexpensive. Extra arms and landing gear are available and inexpensive. Again, they are durable, but I have managed to break a couple. I would order a couple of spares with an initial order. Highly recommended. Have fun!For the price I'll happily give this 5 stars all round. The kit arrived today and while watching sitting down to a movie with my wife I starting putting it together. In just 90 minutes it was ready to fly. I built mine with: Naza Lite (no gps) Q-Brain 4 in 1 ESC, Sunnysky 2212 - 13 980 Kv motors, DJI 10 x 3.8 props. Frsky Futaba compatible receiver, Turnigy Nano Tech 3S - 4500 battery.
I also mounted my motors inverted on the underside of the arms just to try something different. It flies perfectly and I get 19 minutes flight time with this combination.
Overall an honest little quad that flies great and is a bargain. Very strong arms.Dissapointed... The arm quality is superb. Very strong and wont flex. The carbon plates however are poorly designed and allow only for a configuration unless you simply double sided tape the control board on. The space between plates is very small and doesnt allow for any control board or Rx with vertical pins. However, once you have figured a layout and gotten everything onto the quad it does appear to fly well from initial tests. More tuning required and ill update the review.
