The NoVa is an attitude stabilized quadrotor. It utilizes paparazzi hardware as well as a 6DOF IMU.
The FunJet is a new electric pusher-prop model from Multiplex made of durable and CA safe Elapor foam. It offers plenty of room internally for avionics in an attractive package.
ENAC Solar Storm
The Telemaster is a great platform for a new Paparazzi user. It provides a stable platform to help a new user get used to the amazing Paparazzi system.
The Jet powered is a special implementation of the Paparazzi system. The TWOG produces a very stable flight with only IR sensors for this huge glider.
The Hobbyking Bixler is a cheap copy of the Multiplex EasyStar. It is very inexpensive, easy to obtain and provides superbly easy flying for beginners. Moderately high payloads are possible.
The Bixler is a five channel aircraft with Aileron, Rudder and Elevator.
| Build by the Geophysical Institute of the University of Bergen, Norway.|
It uses industry standard sensors for temperature, air pressure, humidity and wind speed/direction as well as more specialized sensors as infrared/visible light radiation, particle concentration or ionizing radiation (full list). It has been used in many measurement campaigns by various research institutions.
The installation of autopilot, sensors and modem is described here.
