rc pinzgauer with spur gear differential
objective design and build a differential spur gear transmission and implement it in a 1:9 scale rc model of a pinzgauer. design the rc model features a swing axle suspension similar to the suspension in the original pinzgauer. due to component size restrictions a different gearbox is implemented that allows manufacturing of the gears more […]
jet boat
objective design and build a simple rc jet boat using mostly 3d printed parts. design this is already the fourth design iteration of my rc boat project. the first two worked great in the bath tub. in the real world though the jets sucked in air and consequently lost thrust. the third iteration jet works fine […]
c-47 dakota, rc plane
historic the douglas dakota is an airplane that is well known in switzerland due to a plane that crash-landed onto gauli glacier in the bernese oberland in 1946. to this day remains of the airplane are occasionally recovered from the glacier. some of them are on display in innertkirchen. the dakota existed in several variants (c-47, […]
sno explorer, tracked rc vehicle
objective design and build a tracked rc vehicle using mostly 3d printed parts. prototype a new law regulating the use of larger rc quadcopters is looming over rc pilots in switzerland. this made me think about how i could reuse larger brushless motors in the future since i have many heavy models that will require some […]
rc car chassis 1:16
objective build a simple 1:16 rc model made of mostly 3d printed parts. design i am not a regular rc car driver but i find it it very interesting to design and build rc cars. my previous rc car project, the 1:6 rc car chassis, took quite a long time to design, build and optimize […]
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 […]
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 […]
v-tail rc plane
this is an attempt at building a simple and small fpv plane. simple because the wing is straight having the same clark y airfoil over the entire wing span. small because it has a wing span of 700 mm and weighs around 500 grams. the plane consists of six separate parts, the fuselage, the two […]
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 […]
