Infant Pursuit (oz8176)

About this Plan

Infant Pursuit. Simple all-sheet free-flight model. For Infant Torpedo power, but the plan also shows variants with CO2 and with rubber power.

Quote: "Heralding the age of smaller engines this & B powered ship is forerunner of brand new class. Infant Pursuit, by Don R James.

With the release of the K & B Infant Torpedo, thousands of model builders now have what they've been waiting for since the appearance of the first gas engine. With a displacement of .0194 cubic inches and a weight of one ounce, this little power plant should win a place in most every modellers heart. Despite its small size, the Infant Torpedo is one of the easiest starting engines I have had the pleasure of owning.

The basic Infant Pursuit has been flown with rubber and CO2 power, showing excellent performance with both. The CO2 version was lost OOS a year ago. This ship is ideal for the Infant Torpedo as it is just the right size and is exceptionally stable. Ready to fly, the ship weighs 3 ounces, which makes it resistant to light thermals (if flying out of sight, worries you, color dope can be added to increase weight further).

Now that you're all fired up and rarin' to go, better take a deep whiff from a dope bottle to steady your nerves. The firewall A is cut out first, using 1/16 plywood. Former B is next, 3/16 hard balsa sheet being used. Cement both together and set aside to dry thoroughly. If you are building the Infant Pursuit as a CO2 job, F and G are cut out instead of A and B. For a rubber job, X and Y are required.

The two fuselage sides are next- on the program. Medium 1/16 sheet balsa is used, and don't forget to leave the 'excess' portion intact on the top of the nose section. Don't use quarter-grained wood for these sides, as it resists bending and may split (you can detect quarter-grained balsa by its 'speckled' or 'flaky' appearance).

Cut out the wing and stabilizer slots as indicated by the cross-hatched areas. Now apply an even coat of dope to the Left side of one and the right side of the other and lay aside to dry. While the sides are drying, cut the fuselage bottom from 3/32 medium stock and the keel from medium-hard 1/2 in sheet. Cement together, making certain that the keel is centered on the bottom piece.

If you haven't done it already, drill the two holes in the firewall (this doesn't apply to the rubber job, of course). The 1/2 or 3/4 in long #3-48 machine screws are threaded into these holes from the back..."
