Initial settings if you are using a Non-Computer Radio: 

 Low 

rates High 

rates 

Ailerons  .................  +10 degrees (+3/8-inch)  ...........  +15 degrees (+1/2-inch) 
Elevator  .................  +10 degrees (+3/8-inch)  ...........  +15 degrees (+1/2-inch) 
Rudder  ...................  +10 degrees (+3/4-inch)  ...........  +15 degrees (+7/8-inch)

Trim adjustments: The ailerons and rudder will probably require no adjustments (in all 
probability you will be able to leave them centered, as assembled); however, be 
prepared to set the elevator trim depending on how slow or fast you fly. For example, if 
you like flying low and slow, your M

ENTOR

-G’s elevator may require a bit of up-trim. 

IX.  PREPARATION FOR TRANSPORT AND FIELD SETUP 

1.

 

Unscrew and safely set aside the two screws that secure the wing to the fuselage. 

2.

 

Gently lift and slide the wing back, then lift it up and away from the fuselage. 

3.

 

Disconnect the two aileron servo extension cables. (If your radio uses separate channels 
for each aileron servo, be sure to mark each aileron connection so they always get 
connected to the same channel.) 

4.

 

To reattach the wings, reverse the above procedure. Be careful to firmly connect both 
aileron servos and to snugly reattach (but not over-tighten) the wing hold-down screws 
into the blind nuts inside the fuselage.

 

X.  PRE-FLIGHT CHECKS 

1.

 

Double-check the security of the engine, and make certain that all screws, linkages, 
clevises and other connections throughout the air frame are secure. 

2.

 

Double-check the control directions of the throttle, ailerons, elevator and rudder. 

3.

 

As with all radio-controlled model airplanes, this model must pass the radio range 
ground check recommended by your radio’s manufacturer, or you may not safely fly. 

4.

 

Get into the habit of moving your transmitter’s throttle to minimum before turning ON 
your transmitter, and carefully break-in and operate your engine according to the 
manufacturer’s instructions.
