Step 4
Install the air tank in the pre-cut position below the
radio tray. Follow the installation diagram instructions
from Robart to hook up the remaining air lines. We have
included enough extra air tubing with the optional air
kit to allow for ease of connection. Use approximately 6
inches of air line between all "T' fittings. Add a few drops
of medium CA at the arrow to secure the tank in place.

Step 5
You will need to make a decision at this time about
transporting the model. If you plan on taking the two
wings halves apart for transport, then you will need to
purchase two additional quick disconnects (1 pkg.) and
place one quick disconnect in each of the main retract
lines just before the "T" fittings used to connect the
main retract lines together. If you will be leaving the
wing together, then you will only need to install the two
included quick disconnects inline so the wing can be
removed for transport.
Step 6
Pump the retracts up to approximately 100 PSI so you
can test how long the gear will hold air. Both the up and
down positions must not leak, but obviously the most
critical is when the gear are retracted for flight. The gear
should maintain pressure and only lose a few PSI (less
than 10 PSI) in 30 minutes. If the retracts will not hold air
this long, then please refer to the Robart troubleshooting
instructions on our web-site at the following URL:
