1. A pitching arrangement for a model helicopter, comprising a securing base, a plurality of servers, a main connecting shaft connected to said servers, a supporting ring mounted on said main connecting shaft, a control device operatively provided between said servers and axially mounted to said main connecting shaft, a plurality of connecting rods connecting with said control device, a motor having a driving shaft extending therefrom, and a deceleration mechanism, wherein said connecting rods are connected to said supporting ring, wherein said securing base comprises an upper base member, a lower base member, a first connecting member, and a second connecting member, wherein each of said lower base member and said upper base member are connected by said first connecting member and said second connecting member, wherein said servers are spacedly distributed in said securing base to form a triangular structure, wherein said motor further comprises a driving gear connected to said deceleration mechanism which is mounted on said lower base member, wherein said deceleration mechanism comprises a first decelerating gear and a second decelerating gear, wherein said first decelerating gear is connected to said second connecting member provided between said upper base member and said lower base member through a half-threaded screw, wherein said second decelerating gear is provided on said main connecting shaft, wherein said first decelerating gear is engaged with said second decelerating gear and said driving gear. 2. The pitching arrangement, as recited in claim 1, wherein said control device comprises an outer controller, an inner controller, and a ball bearing, wherein said outer controller has a plurality of protruding elements spacedly protruded therefrom to define a plurality of controller slots between pairs of said protruding elements, in such a manner that an angle of inclination between said two controller slots is approximately 120°, wherein said outer controller further comprises a plurality of controller arms movably mounted in said controller slots respectively in such a manner that each of said controller arms is capable of pivotally moving—approximately 180°, wherein each of said controller arms further has a connecting head portion connected to a server ball joint of one of said servers, wherein said ball bearing is provided in said outer controller, and comprises an outer bearing rim mounted in an outer controller cavity of said outer controller, wherein said inner controller which is received in an inner bearing rim of said ball bearing comprises a plurality of first ball joints spacedly and evenly protruded from an outer surface of said inner controller. 3. The pitching arrangement, as recited in claim 2, wherein said control device is connected to said supporting ring of said main connecting shaft through said first ball joints and said connecting rods. 4. The pitching arrangement, as recited in claim 3, wherein said supporting ring of said main connecting shaft comprises a top cover, a spherical member, and a bottom cover having a circular hole, wherein said spherical member is rotatably accommodated in said circular hole of said bottom cover, wherein said bottom cover has a plurality of second ball joints spacedly formed thereon. 5. The pitching arrangement, as recited in claim 4, wherein said top cover further has a plurality of third ball joints spacedly and evenly distributed at a 72° increment formed on an outer surface of said top cover. 6. The pitching arrangement, as recited in claim 5, wherein said upper base member further has a through hole and a slider base provided in said through hole, wherein said connecting rods are-passed through said slider base and said through hole, wherein said slider base further has an outer peripheral rim connected to a second ball bearing provided in said through hole. 7. The pitching arrangement, as recited in claim 6, wherein said slider base has a plurality of U-shaped sliding slots, wherein said connecting rods are arranged to penetrate through said U-shaped sliding slots to connect to said first ball joints of said inner controller respectively.
