3DR ArduCopter Quad C
Build instructions for 3DR Quad C frame can be found here: 3DR ArduCopter Quad-C Assembly Guide.
Frame with installed power board:
It's higly recommended to insert resistor 1k-10k on power board before battery voltage wire to avoid damage of PX4 in case of wrong installation.
PX4FMU mounted on the first level:
To leave original 3DR frame connectors untouched “Multi-Receiver-Frame-Telemetry” adapter can be used. It can be soldered from:
- 3-pin header for receiver
- 5-pin (or more) header for telemetry
- 2×4-pins header for 3DR frame
I found that it will be better to cut DF13 15-pin cable at 1/3 from Multi connector, not at 1/2 as I have done.
Looks like spaghetti :)
LEDs mounted on top and bottom sides for more beauty in sky especially for night flights:
LED switched by simple transistor key.
