Ghoul III (oz2023)
About this Plan
Ghoul III. Free flight flying wing designed by MM Gates which is designed for small engines or Jetex. Wingspan is 48in. It was originally published in the July 1951 Aeromodeller. This is a modern redrawn plan in PDFvector format.
Quote: "A 352 Sq ins Flying Wing for power units weighing up to 2.1 ounces
EASY to fly, and simple to build, Ghoul III is the latest design by our well-known specialist contributor on tailless types - MM Gates. Why not try one for your baby class diesel or Jetex unit? Its high performance is equal to the best of orthodox designs.
Construction. The wing centre sections are constructed by cutting out the ribs and cementing them to the I in. square spar, then add L.E.'s and T.E.'s which are first roughly shaped. Outer portions are made similarly. The centre section block is made from laminated sheet, shaped to give the correct dihedral. Only the inner ribs of the outer sections need be set to allow for dihedral. All five sections of the wing should be very carefully cemented together, and the joints gussetted as shown on the plan.
Sew the rear undercarriage legs to the trailing edge and cement firmly. The nosewheel legs are pushed into the centre section. Cover with rag tissue, well doped and fuel proofed. Note that before covering, the washout will be insufficient, the tissue will induce further washout into the outer sections quite naturally.
Final adjustments should he made to the washout after doping; but before fuel-proofing. Fins and elevons should be cut from
lightweight 1/16 in sheet and added after covering. Care must be taken in setting both elevons to the same angle.
The method of pylon construction will depend on the motor to be used. This may be anything from a Jetex 200 to an Elfin 1.49..."

* 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.
