Vultee Vengeance (oz752)
About this Plan
Vultee Vengeance. Rubber scale model WWII dive bomber, by Sid Struhl from 1942 Air Trails.
Quote: "This giant flying scale model has real endurance. It flies like a contest job. Vultee Vengeance, by Disney Struhl.
SEARCHING for an airplane that could match the performance of the German Stuka, England cast her eyes toward American manufacturers to see what they had to offer. And in answer to John Bull's problem, Vultee comes crashing through with its latest creation - the Vengeance. The Vultee Vengeance is a two-place dive bomber of the most striking design. Perhaps the most unusual item in that design is the wing. The odd-shaped wing was created especially for slowing the ship in a vertical dive to obtain the maximum accuracy with the bomb load.
The bomb is carried inside the fuselage and is swung into posi-tion for release by a special arm.
Of course, much of the performance figures of the Vengeance are still a much-guarded secret. We do know, however, that power is supplied by a 1,700 horsepower Wright Cyclone engine, the range is 1,000 miles, service ceiling is 27,000 feet, and the climb is 2,900 feet a minute for the first five minutes. Due to the wing design, the diving speed is less than the maximum horizontal velocity.
As a flying-scale model, the Vultee Vengeance is a pippin. Flights are rather fast but exceedingly stable. Flights of two minutes were very common in still evening air. The glide is really something to behold, and when the ship comes floating in for a landing - well, it sure looks like the real thing. The construction is not too difficult, and if the plans are studied carefully beforehand, you should find no trouble in completing your Vengeance.
CONSTRUCTION. Use the half-shell construction method for making the fuselage. This is the best system for a fuselage of this type, since there are so many straight lines in the fuselage.
Cut the fuselage bulkheads to the exact shape as shown on the plans. Now pin the top and bottom 1/16 x 1/8 center stringers in place, then the bulkhead halves on the plans in their proper locations. Now add the remaining fuselage stringers. These are all 1/16 x 1/8 strips of balsa. Put two coats of cement on each joint and be sure that the cement has set firmly before you remove the frame from the plans.
Note that bulkhead K is made from three pieces of 1/16 sheet glued cross-grain. This strength is needed to hold the rear hook. Bend the rear hook from .049 music wire and ce-ment very firmly in K.
Cement the remaining fuselage halves to their corresponding members, allow to dry and then add the rest of the fuselage stringers. Cut the cockpit from 1/16 sheet and cement in place. Add the 1/16 sheet fill-in around the wing joint and the soft 1/8 sheet fill-in to simulate the cowling..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
