NoVa Quadrotor
|
The NoVa is an attitude stabilized quadrotor. It utilizes paparazzi hardware as well as a 6DOF IMU. |
Multiplex FunJet
|
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 Solar-Storm is the result of a conceptual design study for a Hybrid-Solar cell powered MAV. More details... |
Mini Telemaster
|
The Telemaster is a great platform for a new Paparazzi user. It provides a stable platform to help a new user to get used to the amazing Paparazzi system |
Jet powered
|
The Jet powered is a special implementation of the Paparazzi system. The TWOG producing very stable flight only with IR sensor for this huge glider. |
Hardware Installation
The installation of autopilot, sensors and modem is described here.
Misc Airframe Notes
