NOTE: Steps on this page are for builders who have completed the powerplant kit installation ahead of the avionics kit and
builders with flying aircraft.
Step 1: Leave the WH-P149 (WHT) Battery Ground Cable disconnected from the negative battery ground cable until section 42C is
complete then reinstall the cable as shown on Page 45-03, Figure 3.
Step 2: Re-install the Choke Cable, Throttle Cable and Cabin Heat Cable in the reverse order that they were removed. See Page
42D-02, Steps 18 through 25.
Step 3: Rebalance the carburetors on the Rotax engine.
Step 4: Update the hobbs time on the SkyView EFIS system to match the hobbs time from the D-180.
CAUTION: Do not un-plug or plug in any connector in the aircraft electrical system with the electrical system turned on or
any avionics component running off a backup battery!
Only adjust potentiometers using the TOOL-00000 Trimmer Adjustment Tool. If necessary carefully sand down the tip
diameter of the trimmer adjustment tool to fit within the adjustment holes in the case of the AV-50000A Control Module.
When adjusting the potentiometers it is possible to run off the end of the adjustment range. The item being adjusted will
then be completely turned off. If this happens turn the pot back into the normal adjustment range. The potentiometer has a
built in clutch system which prevents damage if the potentiometer is turned past the end of its travel.
The four screws that attach the AV-50000A Control Module to the F-1202B Panel Base provide a ground connection. Do
not power up the electrical system without the control module attached to the panel base!
Step 5: Make the potentiometers easily accessible. Remove the SkyView display then temporarily remove the four mounting
screws that retain the AV-50000A Control Module. Gently pull the control module through the display opening in the panel leaving
all the harnesses attached.
If the routing of your harnesses prevent this remove the F-1240 Upper Forward Fuselage Skin to grant
easy access to the control module.

CAUTION: Only use a battery charger compatible with your battery's specifications.
NOTE: If the SkyView AP-Knob Panels kit Section 58 has been installed skip Step 2.
When using the knobs modules the trim rate will be controlled by the
SV-AP-PANEL module which is pre-set with factory settings when the latest
firmware-settings file is installed from the Van's Aircraft web site.
Step 6: Double check that trim tab motion properly corresponds to trim switch input.
Use a battery charger to bring the bus voltage to approximately 13.6 volts.
Verify the time to run the trim motor stop to stop is approximately 25 seconds.
The potentiometer is a 25 turn device. Turning the potentiometer clockwise will
slow the motor travel, conversely turning it counter clockwise will speed the
motor travel. After the first flight this setting may be fine tuned to
builder preference.
