1.6 Locate the 8 oz. tank and assemble it. The PC is designed to fit snugly around this particular tank with the vent bubble
at the top of the tank. Proper tank assembly is important to insure good fuel delivery to your engine in flight. Have your hobby
dealer or an experienced modeler check your tank assembly and test it for good "clunk" operation, prior to flying.
1.7 Identify prepunched holes such as those in the fuselage bulkheads and, using a sharp hobby knife, remove any
remaining material in the holes. Do not tear the material as you remove the scrap. Cut it first, then remove it.
1.8 Finally, it's time for you to play around with gluing some scrap AirCore material. It's important that you do this before
gluing the actual kit pieces so you can get the "feel" of working with AirCore and contact cement. We use disposable foam
brushes with contact cement. They can be stored in zip-lock bags for a while between glue jobs without drying up.
HINT - BE SURETO TEST GLUE ONLY ON SCRAP PIECES OF AIRCORE!!! Locate a scrap piece of AirCore and cut off a couple of pieces
about 3" square. Get out your contact cement and thoroughly coat each piece with cement. Then, wait until it is no longer
"tacky" (usually about 3-5 minutes). Note - if you try to press two pieces together while the glue is still wet, it will not bond.
In fact, it will be gooey" and stay that way. Try it! Once dry, press them together and apply pressure for a good bond. If
you've done this right, you'll find it's a very strong bond. Now experiment with some more scrap until you are comfortable
with the process.
We've found that the cement will maintain its ability to bond after being applied to AirCore for at least a half hour. So when
you start building, you have plenty of time between coating the AirCore and actual assembly. You won't ever have to hurry.
If it goes past the stage where the glue can bond, just brush on some more cement. Remember that contact cement is like
trim tape. You really have only one shot at lining stuff up before making a bond - so take your time! As a test, coat two
pieces of scrap and let them sit for 30 minutes or so until you join them together - see, it works!
When using contact cement, we've found it important to get a good, thorough coat on a piece, not leaving any "holes" in
the coverage. It's also important not to "glob" it on, but to brush carefully for a nice, even coat.
When marking AirCore, we've found that ball point pens work best, rather than rolling writers or felt tip pens. However, if
you are marking a spot that will later be exposed, a felt-tip pen or lead pencil works best since you can later "wash" it off
with detergent or alcohol. Find both types of markers and have them handy during construction.
When gluing, use newspaper or butcher paper to protect your work surface. Frequently change the paper between gluing
jobs to keep from getting globs of glue on your airplane where you don't want them.
