rc paraglider

In one of my semester breaks from university I decided to start building a RC paraglider from scratch. I figured it would be one of the simpler and more stabile aircrafts compared to Quadrocopters or similar. All of the construction, electronics design and programming has been done from scratch.

hardware specs

Frame out of wood (and hotglue, yays), roughly 500g
Brushless Outrunner with 1300 RPM/V
Two servos for brake/direction control
Powered by a 6.6V LiFePo4 accumulator

electronic specs

Small fail-safe servo+motor board using an ATTiny2313
RFM12 radio module (connected to an ATMega8 used as an 4800 baud UART bridge)
RaspberryPI + GameCube controller + RFM12 UART bridge as a remote controller

software

servoboard (ATTiny2313)

rfm12 uart bridge (ATMega8)

glider rc control (C# / RaspberryPi)
