Part 6 - How to Design DTFB Planes
This article is a presentation of my scratch built quadcopter.
The frame is built entirely out of wood. The booms are 15×15 mm pine wood that are painted black. The electronics box is made of balsa that I have covered in Oracover, as I traditional wood airplane. I have used landing gears that are intended for use on airplanes, but instead of wheels, I have made plates out of plywood.
I use the KK2.0 flight controller. This is my first quadcopter, and I was surprised on how well the KK2.0 works and how easy it was to setup. I have only flown a normal model helicopter before, but this thing is mush easier to fly. It can be flown with very high precession. The built in voltage alarm feature is also a great feature.
I run two batteries in parallel. To prevent current from flowing between the batteries, they are connected using diodes. This makes it harmless to connect the batteries, even if the are not exactly the same voltage. It also ads redundancy to the system, the quad can still fly if one battery fails.
A standard 7805 Voltage regulator supplies the 20A opto ESCs and the flight controller with 5V.
The camera is mounted to the quad using three pieces of silicone tubing. This acts as a vibration dampening system.
DT750 motors and 20A opto Multistar ESCs.
