Hobby King Sky Eye Adjustable Motor Mount

This two piece mount is CNC machined from billet aluminum.  It is designed to adapt a large range of 35mm and 42mm diameter outrunner motors to the Hobby King Sky Eye FPV / Glider. It will allow for four different motor mounting heights to accommodate propeller sizes up to 12" in diameter.

With this feature you can easily run a lower KV motor with a larger propeller for more thrust and better efficiency. This would be a perfect combination for FPV pilots looking for longer flight times and a more quiet platform.

Swapping motors from a 35mm outrunner with an 8" prop to a 42mm outrunner with a 12" prop can easily be done by removing a few screws.  There are a large number of motor / propeller combinations possible with this setup.  This is ideal for those looking to achieve the best performance possible.

Position 1: stock height up to a 8" prop.
Position 2: (+) 0.47" for up to an 9" prop.
Position 3: (+) .95" for up to a 10" prop.
Position 4: (+) 1.42" for up to a 11"-12" prop.

Three step installation:

1. Glue motor base tube into the fuselage (nacelle) making sure mounting flange is square.
2. Attach new motor to motor plate with supplied flat head screws.
3. Attach motor plate to motor tube at desired height with suppled pan head screws.

Included: 1 - Sky Eye Base Tube and SSS Motor Plate, 4 motor screws and 4 mount screws.

Total Weight: 35g

Dimensions:  I.D. = 1.5" (38mm)  / O.D. = 1.6" (40.6mm)  / Length: 1.37" (34.8mm)

Notes:

The stock thrust angles are retained in all 4 positions. If a change in thrust angle is desired, simply add a small washer between the motor base and motor plate at the appropriate locations.

The stock motor will have to be removed before tube installation.  Some minor foam cutting may be required to reach the screws securing the original motor.

If using the stock motor with our mount, please verify the motor screw spacing.   If motor has a 16mm x 19mm spacing, only the two 19mm spaced screws will line up.

Center of Gravity should always be checked and adjusted per the user manual after installation of a new motor.
