About this Plan

Wild One. Radio control aerobatic model.

Quote: "An airplane designed for free-style aerobatics and will do knife-edge maneuvers. The Wild One, by Norman Rosenstock and Bill Winter.

THIS is a fast, wild, over-controlled trolled airplane for free-style aerobatics and is intended for the competent multiflier and definitely is not a project for the beginner. It is small (54-inch span), powerful (Enya .60), and highly aerobatic (maneuvers include knife-edge flight for over 500 feet with-out loss of altitude, and right or left snap rolls, right side up or inverted). The original weighs 7 pounds but easily can be built to weigh in at less than 6-1/2 pounds - go careful on the paint! Many maneuvers can be left to the imagination of the builder with an airplane having this power-to-weight ratio in such a small package. It will snap roll going straight up.

The basic design was evolved froen the Raider 10. The tail moment was increased three inches, stabilizer area reduced by 25% and its location changed to the top longer on position. Vertical tail area was increased, with 75% of the area put into the rudder. Thinking here is that the rudder is sel-dom used except for drastic maneuvers, such as spins, snap rolls, or for taxi maneuvering in a strong wind. If rudder is needed, usually one wants all he can get. In this case the fin is only some place to hang the rudder.

In the Raider 10 the top hatch is long, extending from the trailing edge position to the firewall. The top hatch permits easy access to equipment - as for trimming - without disassembling the airplane. However, the large open-ing weakened the fuselage. Inasmuch as the tank rarely needed access, two hatches were substituted for the one big one - one for the tank and the other for the equipment section. This is evident on the plan.

The wing is a Jenny Foam-core wing from Custom Products. You can get this core with landing gear blocks, although I installed the gear blocks in the standard core wing. The dihedral angle was reduced, with only one inch elevation at each tip - a total of two inches.

The stab also was foam, made from leftovers from the wing core package. It can be cut out roughly with a hand saw and sanded to final shape. A 1/4 sq trailing edge and tip blocks are attached first to the core, and shaped to agree with it, after which the 1/16 sheet balsa skin is put on with any of the available contact cements recom-mended. The wing is standard, except for the landing gear block - balsa trail-ing edge and tip blocks before sheeting, as on the tail. Specifications are given on the plan.

The wing uses DuBro hardware, including the 120-degree aileron bellcrank, and horns. Covering is optional - I used silk and Hobbypoxy. The fuselage is made out of 1/8 inch sheet, 6 x 48, one for each side. First step is to glue the motor mounts in the proper loca-tion, then the A-inch sheet doublers grainsame direction - leaving spaces for the bulkheads.

The fuselage is all sheet, except for three blocks in the nose, as seen on the drawings. Note that one of these blocks is recessed for the battery pack, which cannot fly about in a crackup. The wing is held in place by a single dowel in the front for keying, and either one or two nylon screws (I used two). The dowel is N and projects into a 3 diameter receptacle (dowel) drilled to take they dowel pin. The receptacle is set in place with epoxy and must be care-fully lined up... "

Notes

* 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.

Scaling

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.
