Quanum have raised the bar of expectations and real value with the release of their PRO series of multirotor frames. By bringing top quality materials, manufacturing and design to pro-spec frames, Quanum are ready to take on the big boys.
The Quanum 680UC stands for its 680mm wheelbase and UC for umbrella carbon. Umbrella because of the way the arms fold, this unique design allows for the frame to fit into a back pack verses the alternative of folding a few arms horizontally, but still needing to deal with 700mm of length. The carbon is noted because of its all carbon and CNC aluminum construction, no plastic in this airframe. Quanum is using top Quality wrapped carbon not extruded like so many others, and have developed matched accessory’s to maximize the frames use. This is what makes it a PRO in the Quanum line-up.
The Upper center frame and arms quickly detach from the lower subassembly and landing gear, allowing for a wide range of optional objective driven platforms to easily be swapped out with 4 quick thumb screws. The upper platform is a standalone Hexa-copter housing the FC, esc, motors and the arms quickly can fold downward for an unbelievably small and easy to transport assembly. The subassembly houses the accessory rail, battery platform and 18mm carbon tube tall landing gear. The accessory rail allows for the CG and the camera to be placed in the optimal locations for maximizing a prop free view angle and CG flight stability.
The CNC aluminum work is top quality and design to optimize Aluminums strength and weight. All connections points are CNC aluminum, the rotating blocks for the folding arms and the motor/ESC mounts. The motor mounts support an integrated esc mounting with contact cooling and has provisions for a wide range of motor mounting options as well as Y6 configuration.
One of the best features of the 680UC is the support and accessory available. The 680UC has full parts support and direct fit optional features like retractable landing skids for a 360 deg camera view. The Workmanship, portability, broad utilitarian use and full support make the new Quanum 680UC Pro a clear benchmark for the 600 class.

Very nice but a bit more flexible battery mounting option would be good.This product is selected as the new drone frame. There is currently a flurry assembly is complete, and very satisfied.The aluminum parts make this way better quality than the Tarot version , all the electronics fit nice and neatThis is a pretty good quality kit. The only reason I rate it 3 is that some parts in the kit were wrong and dealing with HK customer service is tedious at best. There are small platforms in the kit for the ESCs to mount on that are on hex standoffs (page 3 of manual). The bag of hardware(A0013) has the standoffs and the screws. I turns out that the screws are M2.5 but the standoffs are M3. This means you either need 24 M3 screws or 12 M2.5 standoffs to assemble the kit. HK customer service wouldn't process the RMA without a video showing that an M2.5 screw doesn't work in an M3 hole. Once they had the video they said they don't have parts so either buy them yourself or send the kit back. It took yet another chat session to finally get them to send me a $2 bag of M3 screws since they don't have M2.5 standoffs. They try, and they do respond but you have to keep at it to get anywhere with them.This is the coolest frame if you want a large drone, the way the arms fold down protect my gimbal and GoPro during transport. The parts are all very well made and seems to me this frame should cost a lot more for this level of quality.This hexa will be my second build, and for the money great entry level "professional" quality frame, plan on using for photography platform, spare parts are readaly available from HK. Believe it or not but there were instructions and got the job done. will start flight test early 2016I set mine up with the Multistar 268kv motors and 20A HV AfroESCs to run on 8S, all controlled by a Pixhawk.
Without a payload I get flight times of 20 minutes with 2 4S 5000mah 25C Turnigy batteries in series until they are discharged to 3.66V per cell... I think that gives a nice safe margin, and should provide 12-15 minutes of flight time with a DYS gimbal and a sony a6000 under it.
Now about that kit, I do like the quality of the carbon seems strong. I do not like the folding mechanism, and have decided not to fold this frame at all, hence the 1 star deduction. Also the frame has limited space inside it after installing the escs and a power distribution board there is little to no space left in between the carbon sheets, which is a shame as the FC would have been neatly tucked away in there...
I have not tested the retractable gears, but can tell that I should order some spare carbon tubes for the landing gear, as they seem a little thin to me will probably easily break on a rough landing.Quality product!Fit and finish are excellent. I will say that it is pretty tough getting all the components on it. The pancake style main body boards are great but don't leave much room between them for "stuff". I added another small board on top with standoffs. Works great!. I highly recommend it.The frame is really great. I had no one problem with assembling. Just downloaded the manual and in 20 minutes it has been finished. I have only one recommendation. Do not tight the landing gears before installing the frame. Install the frame, level all and only then tight the gears.The frame had some problems, first you should maybe try to retread the holes for the screws, which hold the arms, because the screws dont fit in there very well, which made me to break one. Second you will maybe have to replace the arms because they don`t fit in the holders for it. Third there is no gimbal holder with it, like it is shown in the pictures. And last it seems to me that the arms arent all level.
