'''''...UNDER CONSTRUCTION...'''''
 
The ENAC team has been working on long endurance airplanes for a while now. It appeared that one of the many limitations was the integration of the electronic part into the new fuselages which are becoming thinner and thinner. So we started to work on a new version of autopilot mainly based on the well-known tiny. The new sensors becoming smaller and smaller, we were able to integrate onto the board the IMU and a new design of barometer. So now, the ENAC team is proud to present you the UMARIM! (which means "I Hope" in turkish)
