Trio Avionics Wing Servo Mount Installation for RV-7, 8, 9 and 10 - Manual (Page 7)

From the Trio Installation Manual
7.8 Repositioning the Servo Crank Arm
To suit your particular installation, you may need to reposition the servo crank arm to get the
correct geometry to drive the roll control system. This can be accomplished by rotating
the crank arm to one of 4 positions, in 90 degree increments.
It is important, because the screws are secured with Loctite®, to apply heat with a heat gun
before attempting to loosen the four screws. Failure to heat the assembly will
more than likely cause the screws to break off when being removed.
To reposition the servo Crank Arm, perform the following steps:
1. Use a #2 Phillips screwdriver to remove the screws.
2. Rotate the crank arm to the correct position for your installation.
3. When satisfied with the positioning, apply a small amount of Loctite® 222 to the
screws, reinsert and tighten the screws.
If you have previously purchased a Trio Gold Standard Servo and need to repositioning the
crank arm on your servo, please follow the directions below.
