The goal of our research is to create a UAV for both non-military and military purposes that do not
need a runway for takeoff and can be efficiently used for surveillance, search and rescue operations
and spying .Through UAV manpower will reduce and verity of application can be performed.We
comparatively analysis the design, control portion, and dynamics of two different UAVs one is trirotor
and another is quad-rotor. In Tri-rotor three rotors are on samedistance from its center.
Contrary to a Quad-rotor, in Tri-rotor the rotorsproduce a unstable reaction torque in system due
to this characteristic it become challenging in modeling, stability and control of tri-rotor.
