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 and 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 main frame is glass fiber while the arms are constructed from ultra durable polyamide nylon. This version 3 of the Q450 features integrated PCB connections for direct soldering of your ESCs. This eliminates the need for a power distribution board or messy multi-connectors keeping your electronics layout very tidy. V3 also comes with stronger molded arms over V1 and V2, so no more arm breakage at the motor mount on a hard landing. Assembly is a breeze with pre-threaded brass sleeves for all of the frame bolts, so no lock-nuts are required. It utilizes one size of bolt for the entire build, making the hardware very easy to keep in order and only requiring one size of hex wrench to assemble. A great feature of this frame is the large mounting tabs at the front and rear of the main frame bottom plate for mounting cameras or other accessories.
