SJM 400-III (V3) Pro is third-generation product developed from SJM 400.It adopted more strong and stabalized metal rotor head and tail unit than SJM 400. Aluminum alloy,carbon and fiberglass constuction is also its distinctive features,the belt driven tail system is more simple,it will let the players enjoy the highest machining precision.

Furthermore, This SJM 400-III (V3) Pro 3D RC Helicopter Kit (CNC 400) structure consists of high quality aircraft-grade aluminum and fiber glass components processed through advanced CNC manufacturing techniques only by a certified manufacturing facility, to insure reliable and enjoyable e. The SJM RC Helicopter Kit (CNC 400) is already proving to be the best value in miniature R/C helicopters on the market today. This helicopter design is same as the Apl 400 with lower price.

• The whole helicopter is made of aluminum alloy, Carbon Fiber, and fiberglass material and through CNC technology
