Vultee Vigilant (oz661)

About this Plan

Vultee Vigilant. 52in span gas free flight of WW2 liason-observation monoplane by J. Bridgewood.

Quote: "A US Army spotting aircraft is the prototype of this free-flight scale model for .75-1 cc motors. Vultee Vigilant by J Bridgewood.

This is my seventh scale powered model within three years and it has proved to be the best, being most stable and least difficult to trim. Providing the weight is kept down to 18 oz, any engine from .75 cc should supply ample power."

Commence by building the tailplane, as this is needed before the fuselage can be completed. Elevators are made separately and lightly cemented together after the tailplane has been fixed to the fuselage and covered. This gives more scale detail as well as making it possible to crack the cement joint and adjust the elevators for trimming.

Fuselage. After building the crutch, attach the top half formers F4, 9, 10, 11 and 12, add the top stringer from F9 to 12, then window frame stringers from F4, F9 down to 12. Now fix eight 1/4 x 1/8 strips between these and the crutch. The remaining six stringers can be fixed after notching the formers. The tailplane can be cemented in position and the end of the stringer cut to correct length and fixed.

When thoroughly dry, add all bottom half formers and stringers, not forgetting to bind and cement all tubing for the undercarriage.

F1 and 2 can be fixed along with the engine bearers. Fill in with in. sheet where shown and plank with 1/16 sheet from F1 to 4. The two 1/8 in sheet ribs of the cabin are faced with celluloid to give extra strength. The entire green-house is covered with seven separate panels of celluloid..."
