Five years ago first student uav competition of Iran was held by "Shahid Rezai" research institute of Sharif university of technology. The competition was held in three phases:
1-Conceptual design
2-Non-Flying prototypes
3-Flying prototypes
In first stage 20 teams could reach to second stage  and in second stage 8 teams could reach to final stage. Final phase was held in four stages of flight tests. After final phase of competition no team could acquire required points for first and second rankings, but third place assigned to Shahbal-1 team from Malek-e-Ashtar university of technology and forth place assigned to  "Shahbal", "Parastoo" and "Arya" teams (from Sharif university of technology,Science and Research branch of Islamic Azad university and Isfahan university of technlogy) jointly.
