Excellent Frame!!

Very well made!!

There is NO plastic anywhere on this... everything is either carbon fiver or aluminum. The frame and folding mechanism is very functional as well.
Everything goes together very smoothly. Most of the screws are of M2.5 thread, and go into tapped aluminum pieces. Make sure to use loctite on these.

Overall a great bang for your buck, and it looks like a professional level rig!!

This is my first build. The instructions were very good and did not take a lot of time to build.

This is my first build. The instructions were very good and did not take a lot of time to build.
It took a while to spec out the motor and ESCs to build the Hex. I had to contact HK to determine the items used in the videos. I installed a NAZA V2 controller and the design worked very well.

The only one minor problem I found is I had to be very careful on motor alignment because of the tolerance in the bolt holes. The out of alignment resulted in drift of the Hex. I adjusted the motor rotation and the drift was eliminated. This took about 20 minutes to correct because I was checking alignment during flight.

The retracting landing gear can take a lot of drop and still survive!

With no camera the battery had to be mounted directly under the center to balance the Hex.

The best modification to the design was to add spacers on the hinge bolt for the motor arms. This was installed between the hinge ears at this location. This prevents bending of these ears.

Very nice but a bit more flexible battery mounting option would be good.

This 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.

I 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.
