About this Plan
Cutlass. Free flight flying-wing model. Wingspan 29 in for .05 power.
Quote: "Tired of the conventional? Get out of the rut with this unique flying-wing for the smaller capacity diesel. Easy to build and fly, it has a high performance and is virtually crashproof!
WE WERE first attracted to George Bravey's swept flying wing at the 1953 Yorkshire Evening News Rally where it made many consistent flights to the delight of a group of admirers. Then again, at the '53 All Britain Rally, Mr Bravey made further impressive demonstrations with this 'suitcase size' design, which we thoroughly recommend to all sport flyers.
When we say 'suitcase' this is no exaggeration for the largest portion of the dismantled Cutlass is no bigger than 15 x 6 in - surely no problem for transportation! Breakdown into small parts for easier carriage also adds to the crashproof qualities of this design, for any hard knock taken on the wingtips is easily shockproofed by the split wing fixing at the centre section and elastic band assembly.
Wings: Cut out the ribs using a template on sandwich method. When cutting the spar slots remember to cut at an angle. Construction is normal and to ensure accuracy with the elevons build these in with the wings but remember to set the end ribs of the elevons at an angle while building.
Wing end ribs should be left off until the rest of the wing has been finished. Then cement in and while drying prop one wing tip up 1i in. and then set the angle on the ribs. This ensures accuracy. When set, mark paper tube position and bore holes through the ribs which accommodate the tubes.
The 1/16 sheet at the wing root is let in between the ribs. Bore the hole for the rubber bands and set in paper tube.
Tubes for the fin mounting can be made around a bicycle spoke, holes bored, and the tubes simply smeared with cement and pushed in. Fuselage: Cut out the fuselage sides following the grain as per plan. Cement the respective sides together setting in a slight curve which makes for easier building later.
Lay the engine bearers on the plan and cement in the in. centre spacer using Durofix. Drill bolt holes. Using Durofix again, cement the fuselage sides onto engine bearers.
Cutlass is the name of a full-size American Navy fighter with similar sweepback and twin fin arrangement as George Bravey's model. This model Cutlass also has an interceptor-like performance and zips off the ground after a long take-off run to build up speed. Assembly of the components is simple, as seen in the photo at right..."

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.
