Vought F7U-1 Cutlass (oz15598)

About this Plan

Vought F7U-1 Cutlass. Scale model for Jetex 100 power.

Quote: "The Cutlass is the US Navy's first tailless twin-jet fighter and although rather large for duty as a carrier based fighter it has been enthusiastically acclaimed by those who have sampled its flying qualities. Readers of the American magazine Aero Digest will no doubt have seen the comprehensive write-up on the Cutlass.

An important feature of the model Cutlass is the 2 deg 'toe-in' on each fin giving a drogue effect which contributes to directional stability.

Fuselage: Pin pieces A and B to the plan. Note that A carries the nose block profile, and B carries the profile of the fairing between the twin jet orifices at the rear. Pin 1/4 x 1/16 backbone and 'trough strip' pieces in place, cementing joins. Cement piece D in place on the trough strip. Cement half formers 1, 2, 5, 6, 7, 8, 9 and to perfectly upright over their positions on the plan. Add piece 12, which forms the cockpit cover base, then cement formers, 3 and 4 in place. Cement piece C into the notches in formers 5 and 6, 7 and 8. Cement the 1/6 square stringers into the notches in the formers.

Remove this side from plan when dry, and cement the opposite side formers and stringers, etc in position. Add former 11. Cement the piece of 3/8 x 1/4 balsa into the slots in formers 5, 6 and the recess formed by piece D and former 7. Add the noseblock in two halves and also the pieces of 1/8 sheet on each side of B at the rear.

From a commercial 'bubble cover' cut the centre portion of the cockpit cover, add the windscreen cut from celluloid to the pattern shown, and the rear fairing cut from notepaper to the pattern shown. Cement the notepaper trough pattern in place in the recesses in formers 7, 8 and 9.

The original model required the addition of a small amount of nose weight; this may be avoided (to advantage) by filling in with 1/16 sheet between stringers and between formers and 2.

Cement and screw the Jetex 100" clip in the position shown. Add the 1/8 sheet surround to the air intakes on former 5 (each side) and sand off the corners. Sand off all former protrusions and rough corners on the stringers..."
