Attach Red air line to each retract cylinder so that when air is applied it will cause the gears to
deploy. Use enough line to have the lines exit 1 foot as the previous door lines did before.
Repeat the previous again but use Purple air line on the retract side of the gear cylinders.
Attach a 14" length of CLEAR tubing to each brake nipple.
Like you did for the other airline colors, connect the remainder of the clear brake line to a Y
connector and to the two brake lines.
Secure the brake lines to the struts by using clear tape or tie wraps. Do not over tighten the tie
wraps and restrict the air flow through the lines. There are also clips especially designed for this
that can be purchased from you dealer.
Check that each retract is properly secured into place.
Check the wheel alignment for toe in and toe out. The first spring should be compressed before
you adjust the wheels by putting the weight of the model on a table. The wheels should be
pointing straight forward. If they are not straight, loosen the trunion bolts to straighten them and
then retighten the trunion bolts. It is good practice to recheck tightness of all bolts just in case
the factory missed something.
Blue thread lock is also a good practice to use on any threaded bolts as it works like a lock
washer.
Never use the Red thread lock as it is for a permanent install and requires lots of heat to be
removed.
3: FUEL TANK SYSTEM
The F18-f has a 3 tank fuel system. The main is 88 oz with 2 - 40oz saddle tanks which are just
behind the CG of approx. 5½” to 6¼” from the wings leading edge. They are connected in
parallel, then “Y” connected to the main tank and then to a UAT or similar header tank of choice.
The total capacity is 168oz or 5.25 Liters. BVM UAT
There is not much to go wrong, but like the pneumatic system it does need to be done right the
first time with some careful craftsmanship. Like the airlines, all fuel lines should be cut off
square. Each fuel connection must be given a tie-wrap or fine wire for extra leak security.
