Micro tricopter

thingiverse

I've built a small tricopter but struggled to find plans until I discovered this design. The tricopter uses a KK2 control board and Turnigy 1811 2900kv motors, with 17cm between motor shafts and 29cm from each propeller tip. It weighs just 170g with a 1000mAh battery, offering flight times of around 11-12 minutes. The tricopter is assembled using zip ties for easy part replacement, though I've not needed to replace any yet as it holds up well. Soldering is required for assembly. The design has been updated several times, with the latest version featuring a reinforced center body and a 9g servo mount, along with a Sketchup file for customization. Printed with PLA plastic at 200 micron and around 7% fill, the tricopter requires two front arms to be attached to the main body with snug zip ties, while the rear arm/pivot uses hinge slots and 1.1mm music wire. Zip ties also attach the tail and serve as servo mounts. Two servo options are provided, including a 3.6g option and a 9g alternative, along with a KK2 multirotor control board, 5030 propellers, a FrSky VD5M receiver, Turnigy 1811 brushless outrunners, Turnigy Plush 6A ESCs, and a Turnigy nano-tech 1000mAh 2S lipo battery. KK2 board settings are provided for optimal performance.
