An excellent 700 size Hexacopter frame that is of a very rigid and robust construction. Many of the metal parts have been CNC machined from solid T6 aluminum, the booms are also manufactured from heavy duty thick walled T6 aluminum. The other frame parts are made from high quality carbon fiber and glass filled nylon making this a very strong frame indeed, at a price that will not break the bank.
The function that sets this apart from other 700 size frames is that it is supplied with a beautifully made set of mechanically retracting landing skids which makes it an ideal platform for aerial video and photography. The retract units are once again very nicely made with CNC T6 aluminum parts and features a really nice metal machined spline to fit straight onto the servo unit. This makes the whole assembly very rigid and slop free and the operation is as smooth as silk. In the down position the geometry of the system goes over center and locks so that there is no load on the servo when the legs are in the down position with the weight of the hexacopter on them.
The S700 suits a variety of motors that have 19~25mm mounting holes (max prop size 13") and there is masses of room for all the other components on the large central platform. The battery mounts underneath in the normal manner on a tray that can slide backwards and forwards so as to achieve the correct balance.

This is really a nice looking frame and the body is big providing adequate room for lots of equipment. The problem is (as someone noted in the discussion) that the screw heads easily strip. They use a really small hex and the screw metal feels really soft, I've had several screws strip, making it difficult to service, rework, or unscrew/re-screw some of the parts.
To avoid any frustration, I would suggest trying to find replacement frame screws before building, ones with a larger hex screw head. I've asked HK support for which screws I can use to replace these and am waiting for a reply.
Overall I'm quite impressed with the kit. Very well made, just the Screws are a bit of an issue as the hex holes are not always up to spec - guess the Screw supplier needs to be looked at... HK! But all in all everything fits very accurately - wouldn't be able to machine such parts at that cost.
