Bindli_total_smallest quadcopter #11 (micro fpv 150 mm)

a 3d printed quadcopter having an outer shell as its main support structure was the aim when i designed this small quadcopter. its main characteristics are: 150 mm diagonal motor distance 300 g takeoff weight 3″ propellers dys 1306-3100 kv motors dys 10 a blheli esc’s cc3d atom flight controller (running betaflight) frsky tfr6 receiver […]

210_quad_cat_pic quadcopter #10 (210 class)

the 250 quadcopters are great to take along on hikes for filming. but there is still room for further miniaturization without having to bullnose the 5 inch propellers. the 210 class appears to be pretty much the minimum that makes sense. so here is a homemade 210 class quadcopter. the size offers another advantage, at […]

quadcopter #9 (250 class)

the 250 size quadcopter seems to become a favorite among fpv pilots. this type is small, light, fast, agile and therefore lots of fun to fly. i tried it myself with the following setup: naze32 rev5 flight controller frsky tfr6 rc receiver 2206 2150kV multistar v2 motors turnigy plush 10amp esc’s mini cmos 520tvl fpv […]

hexacopter folding multiwii hexacopter

after having built many different quadcopters it was about time to build something bigger and better. here it is my first foldable multiwii hexacopter. the motor mounts are made of 3d printed abs plastic. they are attached to 15 mm aluminum square tubes. the tubes are hinged to a center plate using 3d printed abs […]

brushless gimbal brushless gimbal #1

this is the first brushless gimbal i designed and built. i hope it will be a useful add-on for filming. it should reduce the shakiness substantially. the gimbal relies on some of the cheapest components i could find for this project. adjusting the pid controller was a pain at first. i am still uncertain whether […]

multiwii quadcopter #8 quadcopter #8

flying near rivers and lakes always comes with a certain probability that a quadcopter crashes into the water, disappearing forever. while my designs are somewhat cheap, the loss of the camera and other equipment would still hurt. therefore i designed a quadcopter with a lot of buoyancy. the quadcopter consists of a 4 mm layer […]

multiwii quadcopter #7 quadcopter #7

this quadcopter has already gone through multiple design iterations. three of these made it into actual flying machines. the design plans for the first can be found here: http://www.thingiverse.com/thing:113703. the design plans for the second can be found here: http://www.thingiverse.com/thing:167001. the third is not yet on thingiverse. the following pictures show the various design iterations: […]

multiwii quadcopter #6 quadcopter #6

this is the first laser cut poplar plywood quadcopter. it is a very lightweight design having a takeoff weight of around 550 grams (including lipo 2s 2200mah). design by sini

multiwii quadcopter #5 quadcopter #5

this is my second foldable quadcopter. since the first foldable quadcopter suffered heavily from vibrations the design had to be made much stiffer. this was achieved by increasing the diameter of the carbon rods, shortening of the rods and increasing the diameter of its body. the design of the quadcopter can be found here. the […]

multiwii quadcopter #4 quadcopter #4

this is my first foldable multiwii quadcopter. it is a very lightweight design and therefore prone to vibrations. in fact, the vibrations were so strong that it was very difficult to fly this multirotor.
