High Powered Gnat (oz10967)
About this Plan
High Powered Gnat. Indoor rubber model.
Quote: "A High-Powered Gnat. Here is a Natty Little Ship that Will Afford You Great Pleasure at Small Cost. By Richard Rioux.
The Gnat completed is small enough to fly in restricted space. Note its size compared to match box.
THE high-powered Gnat has a very high performance-cost ratio. Housed in a kitchen-size match box, it is easily transported and adds amusement to any model airplane club meeting. The model made its spectacular 97-second flight, out of doors, on a very calm hot day. The rubber used was shredded from a toy balloon. The propeller 'pulled' for about 30 seconds; air currents gave it a break for the rest of the flight.
Motor Stick: Make the motor stick of very soft 1/16 x 1/8 balsa. Cut it 3-5/8 long and attach the rear hook and thrust bearing, both being made of light wire, in position. Round off the corner below the thrust bearing with fine sand-paper and polish the complete motor stick.
Tail Surfaces: The tail surfaces are made entirely of soft 1/32 square balsa. Sand all the parts round with fine sandpaper. Make the stabilizer first and cover it on the bottom. Construct the rudder on top of the stabilizer, let dry, and cover on one side only. Slightly sand the end of the motor stick so that the stabilizer will be perfectly level with the bottom of the motor stick. Cement in place and set aside to dry.
Wing The wing goes the extreme in dihedral angle but it keeps the model from rolling as it climbs on. or near, the burble point. The five ribs are cut from 1/32 square balsa and are sanded round. The spars are cut of 1/16 x 1/32. Sand the edges round. cement ribs in place, crack in dihedral, and cover on top. Carefully fasten wing clips in place and set aside to dry.
The Propeller: The propeller is carved from a soft 3-1/8 x 3/8 x 1/4 inch balsa block. Cut along the diagonals and shape in the conventional manner. Attach a light shaft and two 1/16 diameter celluloid washers.
Flying: Assemble the model and put on a loop of fine golf-ball rubber or that shredded from a toy balloon. Adjust the model for the maximum glide, as this model will not stall at such an angle. Take the model into a large hall or auditorium; as very seldom is the outside air suitable. Give the Gnat a row or so of knots and let it go. If it doesn't paddle more altitude under its wing in proportion to any 'crate' in the hall, search the plane carefully for a stowaway that's holding it down.
This plane could have been made with very much lighter parts and covered with microfilm instead of superfine. The heavier model, however, will stand the handling of enthusiastic spectators. Build the model light and you will be sure of success."

* 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.
