HK has updated their growing catalogue with several interesting new multirotor offerings:
The Micro-X is a tiny MultiWii Quadcopter with a lightweight frame that has the flight controller integrated into it. You may be wondering why this is new given that they already have several versions of this available – well this model comes with two batteries, and the DSM2-Receiver is integrated on the PCB. It’s about USD $50.- which is a pretty good price.
The FPV250 frame is a one-piece frame for mini-sized FPV quadcopters. You can fit any 50×50 standard flight controller like the Crius AIO or the KK 2.0/2.1 boards, and it has tabs and mounts for small fpv cameras and video transmitters. Being a one-piece frame means that while it’s very rigid and certainly repairable with epoxy, severe crashes mean you’ll have to buy a whole new frame. However, it’s $10 a piece so we can’t complain!
The SK450 is a ready-to-fly quadcopter featuring a KK 2.0 flight controller, 20A ESCs, four 2213 motors and a full set of 8×4.5 as well as a set of 10×4.5 props. This is an interesting package because not only is the KK flight controller absolutely excellent (even more so with RC911’s amazing “++” firmware), but you get props for both heavier payload (battery, camera) as well as for aerobatic flying. Also included is a Turnigy 5x radio system, so this is really a complete RTF package. The KK 2.0 looks a bit strange, given that they’ve phased out this model in favor of the KK 2.1 recently, but from our tests you should not let that deter you as the 2.0 board flies just as well.
Sadly though the Turnigy 5x, although functional, is pretty much a throwaway radio and brings the package price to USD $190.0,-
If you already have a radio and/or you want a better radio, you should consider building our $120 Quadcopter instead. You can get a really nice computer radio for the $70 you save. That said, the idea is a good one and maybe HK will release a version without TX, or with a Turnigy 9x lateron.

Ok so this is basically the same animal as the KK 2.1, meaning MPU6050 and Atmel 644PA. According to HK, the new thing is “added polarity protection to the voltage sense header and a fuse protected buzzer outputs, in case something is accidentally plugged in incorrectly. The voltage sense line has been updated for better accuracy. The board is clearly labeled and the voltage sense line color has been changed to red for easy identification, making installation and connections a snap.”
