Nomad (oz4868)

About this Plan

Nomad Sailplane. Free flight glider model. Wingspan 45.75 in, wing area 230 sq in.

Quote: "Nomad is a successful attempt to combine good appearance, consistent performance and simplicity in a model. It is also of a handy size and economical to build. No incredible averages are claimed in still air, but on a normal day's flying flights from two to three minutes can be obtained easily, the best flight to date being 4 and 1/2 mins OOS.

Nomad is also popular among club members, and nearly a dozen have been built and flown with satisfaction. The construction is quite normal and mostly of balsa.

Fuselage: Build the two sides together on the plan in the usual manner and fit formers 4 and 5. When set fit formers t and 7 into place, and follow with the rest of the formers ; the cross-braces are then fitted.

Don't leave out former 6, as this prevents the assembly from flexing. All formers are of 1/8. balsa, medium sheet, as this makes a better job when using balsa-cement. Nose-block is 1/8 hard sheet, laminated. The tongue and skid are of 3/32 ply.

The fin is built flat as a complete unit from 3/32 medium sheet, and after being fixed in the fuselage the ribs are built up with 1/16 sheet. The upper fin is of 3/32 medium sheet, and the direction of the grain must be noted. The near portion of fin is used as a trim tab.

Wings: These are also built in the usual manner. The boxes are of 3/32 very hard sheet, cemented well and bound with silk-thread. Fit the 1/8 sq stiffeners to the root ribs.

The spars are of 1/8 sq hard balsa with 1/32 sheet webbing on both sides to the dihedral break then on the front only out to the tip. The dihedral keepers should be made of 1/8. hard sheet as shown on the plan. The leading-edge is of 1/4 in hard balsa.

Tailplane: Fit 1/16 sheet ribs between the leading and trailing edges and sand them to aerofoil shape (Clark Y). When they are set, fit braces X and T and the fin between the centre-ribs. Keep the structure as light as possible.

Covering On the original the fuselage and fin were covered with heavy bamboo tissue. Plane-film would be very suitable.

The wings and tailplane were covered with Jap-tissue. Dope the fuselage three times and the flying surfaces twice. The fuselage and wings will resist warps very well, as the structure is very strong."
