The next evolution of the rotor revolution is here!! The KK2.1.5 is packing new found power with updated sensors, memory and header pins.
The KK2.1.5 is next big evolution of the first generation KK flight control boards. The KK2.1.5 was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts. The LCD screen and built in software makes install and setup easier than ever. A host of multi-rotor craft types are pre-installed, simply select your craft type, check motor layout/propeller direction, calibrate your ESCs and radio and you’re ready to go! All of which is done with easy to follow on screen prompts!
The original KK gyro system has been updated to an incredibly sensitive 6050 MPU system making this the most stable KK board ever and allowing for the addition of an auto-level function. At the heart of the KK2.1.5 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional polarity protected header has been added for voltage detection, so no need for on-board soldering. A handy piezo buzzer is also included for audio warning when activating and deactivating the board.
The KK2.1.5 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.
If you’re new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.1.5 was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be quick and easy.

What do I need to know about flight controllers? You should think of the flight controller (FC) as the brain of your multi rotor UAV. Its principal roll is to stabilised your craft, some more sophisticated flight controllers can also fly your drone autonomously. In order to keep the drone perfectly balanced the FC takes continuous measurements from the Inertial Measurement Unit (IMU). These are electronic sensor devices such as a gyro, accelerometer, compass or GPS that measures the velocity, orientation and gravitational forces of the multi rotor. Based on their signals and command inputs from the pilot, the FC processes the data using complex algorithms and makes adjustments to the speed of each rotor to keep the craft level. A multi rotor has four controllable degrees of freedom: Yaw, Roll, Pitch, and Altitude. Each degree of freedom can be controlled by adjusting the thrusts of each rotor. When it comes to selecting a FC, there is a lot of choice. Some of the notable ones are the KK, MultiWii, Ardupilot, Naza, Rabbit and WKM. Your choice of FC is mainly dependent on what you want and your budget. Advanced FCs generally have more features and sophisticated sensors like gyro, accelerometer, sonar, GPS, Magnetometer. Some flight controllers include the IMU and some don’t. Different FC will have different flying capabilities. The following list states the main ones.
- Gyro Stabilization - the ability to easily keep the multi rotor stable and level under the pilot’s control. This is a standard feature of all flight control boards.
- Self Leveling - the ability to let go of the pitch and roll stick on the transmitter and have the copter stay level.
- Care Free - The pilot can control the drone as if it is pointing in its original direction as the orientation of the copter changes.
- Altitude Hold - the ability to hover a certain distance from the ground without having to manually adjust the throttle.
- Position Hold - the ability to hover at a specific location.
- Return Home - the ability to automatically return to the point where the copter initially took off.
- Waypoint Navigation - the ability to set specific points on a map that copter will follow as part of a flight plan.
You should also consider the quality of the components, software package and importantly extent of support, both official and community based. Then there is the question of compatibility with peripheral accessories. The more advanced systems can communicate with a ground station via a telemetry link, allowing the pilot to program an autonomous flight and track progress remotely. Finally there is cost, prices range from £20 for some of the most basic FCs to over £1000 for the most sophisticated, such as the DJI Wooking.

UK Postage: Here at Flying Tech we process orders Monday to Friday and pride ourselves on our quick turnaround of orders. If stocks levels allow, we aim to dispatch orders placed before 4PM the same day with Royal Mail. Our cut off time for courier delivery is earlier; orders must be placed by 1PM for next day delivery with DHL and 1PM for next day delivery with APC. A confirmation email will be sent when your order has been dispatched. If you wish to change your order, please contact us promptly, as we won't be able to make amendments once the order has been shipped.
We are partnered with several delivery companies including Royal Mail, DHL, APC and Parcel Force. If you have a special delivery requirement or would like to arrange a shop collection please contact us. For small low value orders our cheapest delivery service is Royal Mail First Class; this service aims to deliver the next working day including Saturdays and it can be sent recorded for extra peace of mind – please note this is not a guaranteed next day delivery or trackable service.
For a guaranteed next day delivery we recommend Royal Mail Special Delivery or one of our courier delivery options. Royal Mail Special Delivery will arrive by 1PM the next day and for an extra fee can be delivered on Saturdays. APC Overnight offers next day delivery with full tracking and a 2hr time slot pre-delivery text notification. DHL is a good option for larger consignments and remote locations such as Northern Ireland and Isle of Man. All high value orders are fully insured and will likely require a signature on delivery.
FREE shipping in the UK on orders over £99 (this is a signed for service and insured to a maximum of £40). Please note that the offer only applies to orders with a total weight under 1Kg and that a few products are exempt from the offer, such as LiPo batteries.
International Postage: We are based in the UK, but ship to most worldwide destinations. Postage rates are calculated by the weight and shipment location, the price is quoted during the checkout. Low value order can be sent by Air Mail, but are not insured. Higher value, heavy goods will be sent with DHL or an alternative courier. Orders shipped outside the UK may be subject to customs charges. These charges are additional to any delivery costs and will need to be paid by the recipient.
For our international customers who require a rapid delivery we off a DHL Express service.
