The all new HK PilotMega 2.7 is a fresh look and a revamp of the popular APM based flight controller. Over the course of the ArduPilot project and development of the Open Source 2.5 platform, some known issues and ergonomic challenges have been noted. The goal of the HK PilotMega 2.7 was to fix and improve upon this great platform, giving back to the community a design that is improved and stable and yet reasonable priced, making this super powerful Flight controller a great fiscal option to the 32bit variants. There are 5 major improvement in the 2.7, and all need construction files are available under the files tab for the community to use.
HK PilotMega 2.7 Improvements:
1) 100uf cap in Vcc and 10uf tantalum capacitor added to stop 3.3v bad gyro health issues
2) Replacement of the (not used/redundant) 1.0mm 6p GPS port with df13-4P I2C external compass port, putting the GPS and external compass ports next to each other, making for easier connections.
3) Multifunction MUX port added in the old I2C port location, this lets users select an output from the bonding pad (Uart0, Uart2, I2C, OSD “default is OSD”. This new layout makes data transmission more stable with an isolation resistance.
4) 3.3V and 5V Dataflash/Flashrom swapped trace problem corrected to the AT45DB161.
5) External Compass enable/disable jumper added, verses having to cut a trace wire.
The HKPilot Mega 2.7 is based on the rapidly evolving and refined Ardupilot mega or “APM”, an open source project from 3DR robotics. This amazing flight controller allows the user to turn any fixed wing, rotary wing, or multi-rotor vehicle (even boats and cars) into a fully autonomous vehicle, capable of performing a wide range of tasks even programmed GPS missions with waypoints (with the optional GPS module).
Various user interfaces are available for programing, reviewing logs, even some Apps for smart phones and tablets. The optional telemetry radio allows for two way radio communication giving you full control and provides live data back to your computer or tablet. The list of what this flight controller is capable of has quickly been surpassed by what it cannot, with features, flight modes and supported platforms. The APM project is supported by thousands of users pushing this open source flight controller to be one of the best systems available.

*Note: The reference to APM refers to the ArduPilot project, a family of open source autopilots based on the Arduino open source computing platform, developed by 3DR and the open source community. It consists of a choice of ArduPilot Mega (APM) electronics and a range of free software versions for different vehicles and is governed by an open source creative commons license. This product is based on the open source APM Project from 3D Robotics, the Cad files per the creative commons license is available under the files tab.
*Note: This is not an original Arduino brand product.
Good board, easy to use and setup. The connectors are Molex Picoblade 1.25mm (these are white), not Hirose DF13 (3DR produced boards use these and they are beige). When getting cables make sure you are buying the right one. Arducopter no longer support these boards, so you wont be able to flash firmware higher then 3.2.1. The board is a clone of the APM 2.6, so when looking online for info look up the APM 2.6This FC is awesome and loaded with features for the price. I consider myself a bad pilot and back when I did RC heli I quit doing it because cost from crashes was getting to high. This board with RTL (Return To Launch) has save my lots in what of been crashes. This board has built in gimbal control, gps hook up, etc. A lot for the money, but most important compatible with easy to use software with lots of online instructions.We use this HK version in my College UAS course. We've tested this one verses the name brand that this is cloned from and don't see any difference between them related to setting up, programming or flying. For most students, we save a few dollars when we can, so this is the one the professor recommends the students to buy.Works surprisingly well! Very stable flight. Easy to configure with APM Planner.Great Board for the price. Maintains good position hold with a Quanum LEA-6h Gps. You must mount the controller to eliminate vibration,using foam etc. Using the Mission Planner software is straight forward,firmware I recommend no higher than v3.2 at this present time. Loses 1 star for having the cover screws on the bottom. A lot more practical if you could access them from the top. I'm new to the multi-rotor hobby and found it easy to use and customise. I'm a fan of open source!Bought this to replace my KK2.1 which I had outgrown in five months!!! Looked around at what was available, and really liked the APM model. The HKPilot Mega is a lot cheaper, but still has the same functionality as the real APM Mega. Have got this running faultlessly on my SK450 Deadcat with Q Brain 25A ESC. A few hiccups setting it up, but nothing that Google couldn't sort out for me. I have it running very, very stable with all the tricks ... Drift, RTL, Loiter, GPS, Compass. Really like the downloadable data files so that you can review the telemetry from each flight (not interested in real time stats, just yet). Seem to be getting more flight time out of this flight controller than the KK2.1 - 1 to 2 mins more.Using this on my DIY tricopter and works perfectly! Arrived with no problems. You will have to DIY a foam insulator for the barometer as no foam is provided. Screws are mounted from the base so a pain when you need to open the case when it's mounted on your multirotor. 2 jumpers in the HKPilot- one to be removed if your using the Power Module and another to remove when using an external compass. External Compass port is just below the GPS port unlike the 3DR board. Finish is good and soldering is neatly done. Comes with small bits of foam double sided tape, but I used my own tape instead.
Hooked up to Mission Planner without a glitch and firmware loaded with no issues. calibration via mission planner was troublefree! For the cost...Happy and Satisfied as my tri flies perfectly! Recommended!!My housing was a little warped making it difficult to put together initially. Otherwise really easy to get workingAwesome flight controller! You can do anything with this!Ho installato la scheda su un trex500, non facilissimo, arducopter la versione piu' difficile da mettere a punto, ma seguendo la guida on-line si riesce a metterla a sopperire. La scheda funziona molto bene ed assemblata con criterio, si noti che arriva senza un rigo di istruzioni. comunque 5 stelle.
