Well i will be the first to admit that when  i originally weighed my flight controller purchase options I neglected to look at the KK 2.1.5. My buddy recommended it to me saying it was quite a good controller, but I was looking for GPS, bluetooth, telemetry and plus all the options that megapirates flashed board has to offer and yes i was probably way off due to the fact that this was my first quad build, but don´t get me wrong it has been a fun process learning about how quads work , configuring Bluetooth and getting the GPS to connect, smoking a thing or two,  i would do it again, but if you looking for flight time, easy installation, simple no fuck around controller the KK 2.1.5 is for you.

 Firstly the price is very attractive 24 bucks off Hobbyking, compared to 70 bucks for a Crius or MultiWii pro, the board comes in a foam casing that you can use to mount the controller with on your multi-rotor to protect it from water and light knocks. I believe that you can for a few bucks more purchase a hard case version.

Secondly there are roughly eight or nine wires that you need to get connected and then you are off, all configuration is done on-board the controller using the LCD screen and this is specially handy to making small adjustments to your multi-rotor between flights.

The board has a built-in voltage sensor, once configured the flight controller monitors the battery voltage and gives you a series of warnings  when the battery is close to running out of juice.

The flight characteristics of this board are fantastic, the first flight went well with no adjustments made to the settings, it was simple control and very stabil in flight, it had a slight oscillation, but that could be taken care of by simply dropping the quad and adjusting using the LCD screen and then testing again, much faster that the Crius or MultiWii pro that often require a laptop or telefon.

This board comes with a stabilization or auto-leveling, this can be activated by either flicking an auxillery switch on the radio or using the stick control. Which ever method you choose requires a simple in the menu activation. Auto-level works very nicely on this board, Even though i gradually am learning to navigate a multi-rotor, i still crash with the Crius/MultiWii due to wrong PID settings and so one. They have and still do give me problems setting up. With the K.K i was able to drain several  batteries with out a single crash. You can download newer firmware and a well made manual from this guy http://www.rcgroups.com/forums/member.php?u=367321

Bottom line, i will stick with this board for a while and become more experienced with the sticks, in the mean time I can play around with the telemetry/FTV and all the other fun stuff on my new build. If you are looking for a good simple board that will start you up quick, give you success on your maiden flights and help you gain experience then this is a clear choice compared to the more expensive board that require more additional knowledge...Happy flying
