Product overview
The STEAM AK7192-1 black main shaft center mount set is designed for the STEAM AK700 helicopter. Its main shaft center mount and baseplate are precision CNC-machined from 7075T6 aluminum alloy, with large-frame structures that provide high-strength support. Mortise-and-tenon joints reinforce the connections between the main shaft mount and servo mounting plates. Double-row angular-contact bearings transmit axial forces in both upward and downward directions, while the reinforced frame structure helps prevent high-frequency vibration caused by movement of the helicopter body.
The baseplate also provides mortise-and-tenon connections for the main shaft mount, motor support plate and electronics board, joining these components into an integrated frame structure. The set supplies one main shaft center mount, one main shaft mount baseplate, one electronics board and one carbon fiber plate, together with two fuselage aluminum posts. Assembly hardware comprises eight M3.0×8mm and six M3.0×7mm socket head cap screws, plus six M3.0×6mm button head hex socket screws.
