ZiDrohne - tough quad - 100mm Brushless - fpv

thingiverse

I really loved the "Doinker v3" design, but wanted a slightly larger quad instead. First, I tried the "100mm Whoop Frame", which broke easily with hard landings due to its fragile 90° motor arm angles. So, I scaled up the Doinker v3 and made it even sturdier by adding more details like proportions, smoothing, and an extra base for the flight controller. I also designed a simple plate with two slits where a velcro strip can be fed through to attach the Lipo battery. A top plate protects the flight controller and holds the receiver in place with a zip tie. I'm thrilled with the result, still flying my first version of the frame. The twisted arms that hold the motors are perfect and incredibly stable! They're easy to print and withstand rough landings effortlessly. This quad weighs about 176g with the camera and Lipo battery attached. Additionally, I designed a fpv camera holder that's strapped to the quad using a zip tie. It's slightly larger than the fpv cam to allow for adding rubber shock absorbers (I cushioned it with some old HDD vibration isolators). The cam is held in place by two rubber bands. Some tips for building this quad: the ESC, FC, base plate, and top plate are all secured together using four M2 screws. You'll need to add a spacer between the FC and ESC. The build process involves some tricky soldering, but it's manageable. Motor wires are fed through slits between air ducts. In my case, I routed cables to the voltage beeper on the top side of the quad since I added it late; you can also feed it through the base if planned from the start.
