About this Plan

Bug (The Bug Controliner, with single line Autotrol). Control line speed model.

Quote: "Instructions for Building: The Bug is a control line gasoline powered model. It is primarily designed as a speed model for Class I (Up to .099) and Class II (Up to .19 displacement) engines. The model will show excellent performance if all building and flying instructions are carefully followed. In constructing the model, prepare a small layout board about 18 in long; sandpaper; model knife; and straight pins.

FUSELAGE: The fuselage is constructed as .shown in the step-by-step 'Phantom' Construction Drawings. These drawings are self-explanitory. First lay out one side directly on the plan. When dry, build the second side over the first side. When both are dry, remove from the plan andi build up with cross members as shown. When completed, all cement joints must be re-cemented for additional strength. The plywood firewall must be given at least three coats of cement at the joints,

LANDING GEAR: The formed wire landing gear is fastened to the firewall by means of the grooved basswood blocks. After the cement has dried, re-cement these blocks several times, building up a strong fillet of cement between the blocks and the firewall. The wheels included with the kit are suitable for take-off from cement or wood. For gravel or dirt, use a balloon type wheel.

WING: The semi-shaped wing is sanded to the outline shape shown for the various cross-sections. Note that this is a new airfoil design that has proven stable and fast. Cement the wing to the bottom longerons and F-13, allowing 1/4 in dihedral in each wing. Apply several coats of cement. Add the bulkheads and stringers under the wing as shown.

TAIL SURFACES: The tail surfaces are cut from the printed shet and sanded to a cross section similar to the stabilizer in the Fuselage Side View. Attach the fixed surfaces to the fuselage. Moving surfaces are hinged to the fixed surfaces with the staple type hinges included with the kit.

MECHANISM INSTALLATION: The rudder and elevator controls are installed as shown. Road the instructions on flying with 'Autotrol' before installing, so that you will have a clearer picture of how the mechanism operates.

ENGINE INSTALLATION: Use standard wiring diagram. In addition to the accessories shown on the drawings, a slide switch and booster terminal jaoks can be installed at any convenient location. All wiring joints should be carefully soldered. Drill firewall and mount engihe. Be sure that the engine is clean before installing it so that no oil gets on the wood.

COVERING: Do not cover the model until it is entirely completed. Silkspan covering , included with the kit, can be applied easiest when wet, in small pieces. Cement the paper to the wood. After the model is completely covered, apply several coats of clear dope to the entire model. Then color dope to suit.

COWL: The cowling is built up as shown step-by-step. It is suggested that the inside of the cowl be coated with a fire resistant paint.

FLYING: Read 'Flying with Autotrol' carefully. The Bug is a hot airplane with either an .099 or .199 engine. Take your time adjusting and balancing it and it will turn in record-breaking performance for you. Check the balance point. Adjust center of gravity, if necessary, by relocating batteries. "

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.
