REVIEW - THE 2.4GHZ WALKERA G400 IS A G.P.S. BASED 6-AXIS FLYBARLESS R/C HELICOPTER. THE HELICOPTER IS BASED OFF OF THE WALKERA V400D02 DESIGN MAKING SOME OF THE SPARE PARTS SIMILAR WITH ONE TO ONE REPLACEMENT. THE NEWER FEATURES THAT SET THE G400 VERSUS THE V400D02 APART IS THAT THE RX USES A 6-AXIS GYRO INSTEAD OF A 3-AXIS GYRO MAKING THIS HELICOPTER VERY STABLE TO FLY OR HOVER. THE SERVOS ARE ALSO METAL GEAR VERSUS NYLON ON THE V400D02. V400D02 BRUSHLESS KITS WILL WORK ON THIS HELICOPTER AND FUSUNO V400D02 FIBER GLASS CANOPIES WILL FIT THIS HELICOPTER.

TYPICAL G.P.S. FEATURES OF THE WALKERA G400 INCLUDE THOSE FOUND ON TYPICAL QUADCOPTERS SUCH AS THE WALKERA QR-X350 PRO. THIS INCLUDES ALTITUDE HOLD AND RETURN TO HOME FUNCTIONALITY.
THE G.P.S. FUNCTIONS WILL ONLY WORK OUTSIDE AS THE HELICOPTER NEEDS TO TRIANGULATE AT LEAST 3 LOW LEVEL ORBITING G.P.S. SATELLITES IN ORDER TO FUNCTION PROPERLY. SO G.P.S. FUNCTIONS WON'T WORK INDOORS. ONLY NORMAL FLIGHT MODE. WEALSO WENT OVER CALIBRATING THE G.P.S. COMPASS AS WELL AS DEMOSTRATING THE G.P.S. FUNCTIONS.
