Now that the fuselage is ready we now need to get the mounting plate ready. The mounting plate (part FL1) is a 1/8” light ply part that is cut to fit inside the fuselage. It has the mounting holes for the drive motor drilled and cut in to it. The turret is driven by a small electric motor that has a reduction gear on it to slow down the output of the motor. The motor is mounted on FL1 using two 4-40 x 1” machine screws and 4-40 lock nuts. While there are two output shafts on the motor, only one side will fit the drive disk on the turret. If you look at the motor in picture #1 you will notice that there is an alignment tab next to the output shaft, this helps identify the proper side of the motor to mount. Mounting the motor is a simple matter of placing the screw through FL1 and the motor and then tightening the lock nuts. There’s not much else to write here about this, it’s a pretty straightforward step.
