The Linne Skyray can be built on a piece of glass. These are connected so that differential motion of the lines rotates the bellcrank, causing a pushrod to Building contol line models either forward or aft. Costel Mirzac. Combat and some speed models use rubber tubing "bladder" tankbaby pacifiers, or fountain pen ink bladders, Sexy marvel girls with fuel from a large syringe, to hold the fuel under fairly midels pressure. A tank with a vent on the inner edge, or multiple vents, is usually called a 'suction' tank. This project wants to inspire people, to build a balsa wood airplane from a drawing.

Profile models, where the fuselage is cut out from a single relatively thin sheet of wood with modsls "profile" of the airplane, are simple to build and repair, and are very jodels on trainer models. Again you see my pushrod brace on Building contol line models aft fuselage. Takeoff and landing are from a simulated aircraft carrier deck, with arrestor wires. A tremendous degree of control over how the engine runs in flight is possible by altering the fuel contents, propeller size, pitch, and pitch distribution, venturi size, compression ratio of the engine, and the length of the tuned exhaust, if used. Wing Area sq. For sport flying, non-metallic lines of kevlar, dacron, or other low-stretch fiber materials are commonly used. Pulse jet engines get extremely hot once started, and use very volatile fuels like gasoline or methyl-ethyl-ketone as contrasted to relatively benign, although flammable, glow engine fuel. The origins of control-line flight are obscure but the first person to use a recognizable system that controlled the control surfaces on the model, is generally considered to be Oba St. Additional accessories you may need may include, battery clip, engine head wrench and extra glow plugs. The engine is extremely loud in operation and cannot be muffled, and can be heard for miles under the right conditions. The engine is exceptionally loud when operating and should be operated with hearing Report builder model to prevent damage. This one's on his profile B Some form of brace on the rod at the midpoint will greatly contll that and save your Building contol line models many times. This ship has been flown many times; inverted flight, inside and outside loops, figure eights, Russia and the former Soviet countries are currently the main producers of world-class equipment for this sport, including engines.

Orin Humphries has been building, flying and writing about control-line model airplanes for decades. This is his "Hawg" Corsair for Navy Carrier. All photos provided by Orin Humphries. By Orin Humphries March A recent issue of Model Aviation had a couple of pictures of models that caught my eye.

Each had a really basic building error that apparently needs to be mentioned again for newer people. The first one is a Profile Scale B and it is nicely done overall. In the photo of it I am unable to see a pushrod brace for the long rod back to the elevator.

Let's say for the purposes of this article that the model in fact does not have one. Many years ago when I was leading the Spokane U-Control Club, one of the men asked me to test fly his brand new profile P from a Sterling kit. I declined strongly as experience had brought me to do. However, he would not be deterred until I flew it. Everything was fine until I did an inside loop. The loop relaxed at the back end resulting in a crash.

This was why I don't fly other people's airplanes. He was very unhappy, of course, and it took a bit to discover the cause. I finally spotted the absence of a pushrod brace on the fuselage. When you are feeding in full UP, the pushrod usually is pushing back on the elevator horn if the horn is under the elevator. This places a compression load on the pushrod.

The rod at some point buckles from the high load and lets the elevator relax toward neutral. Some form of brace on the rod at the midpoint will greatly reduce that and save your bacon many times. Don't' go to the flying field without them! I bent a length of. In one photo below you will see I sometimes used a Cotter Pin. Another model with a basic problem in the recent issue of MA was a P The builder had brought out the leadouts at the wingtip.

People make their leadout exits at the wingtip because it works on models with midwing designs. They don't think about it.

What happens with a high leadout location is that the model when flying is rolled in on you. Your line tension is weak and you are susceptible to having the airplane blow in toward you on the upwind part of the circle. Corsair pilots universally complained of this. In the accompanying photos you can see the pushrod guide on my Shoestring Stunter and a Profile B I built for my son.

The B is getting refurbished after its active career. You will notice that the B's bellcrank is mounted ahead of the leadout guides that pierce the nacelle. That doesn't matter.

In the photo where I am hanging it from its leadouts and it is nose-toward-you, note that the outboard wing is closer to me than is the inboard wing. In flight the model would be rolled outboard like this for better line tension. That means that in flight the model would be yawed away from me, again for line tension. Roll angle left , yaw angle right and the pushrod system below for the B under refurbishment.

On my Corsairs, the leadouts emerged from the bottom of the wing a good three wing ribs in from the tip. My A had a wire frame leadout guide suspended below the tip tank. On my soon-to-come F, the guide is projected to emerge along the bottom of the tip tank.

It was frequent that other Corsair pilots had their birds torque roll in on them on takeoff because their leadout exits were on the wingtip, too high. How do you tell where to locate the guide? Leave that detail for last, putting off skinning the inboard wing if necessary. The model must have all else on it for the test even if only taped on temporarily.

First hang the model from its leadouts with the belly toward you and the nose to your left. Grasp the wingtip and rotate the model about its yaw axis until the nose is just a little outboard if it was actually flying , seen as below level, here. Now turn the model while hanging from the leadouts so its belly is toward you. Rotate the nose a bit until it is below level as in yawed away from you if in flight.

Mark that location. You now know the place to put your leadout exit! Never just assume. Always check this. You will be saving your model some bad day when your engine hiccups on the upwind side of the circle. In the photos of the Hawg, you note that the wing is rolled outboard. This is because as said above that I found the correct leadout exit location to be the third rib in from the tip.

Again you see my pushrod brace on the aft fuselage. If you look at the underside of the wingtip, you will note that I did NOT bring the leadouts through on the mid-line; they emerge halfway between the midline and the bottom of the rib.

For this model, I thus get the good outboard roll angle that you can notice in the photo of it hanging from the leadouts. Leadouts exit the Shoestring at the bottom of the wingtip. Correct location will vary based on the airplane design.

Testing provides the answer. Next, while still hanging it from the leadouts, rotate the model so the nose is pointing toward you. Grasp the wingtip and rotate the model about its roll axis so it would be rolled away from you slightly if it were flying.

Both of these angles are necessary for proper line tension. On your lines while airborne it must be nose outboard and left wing high. Physics works for us here, in that how the model hangs on the leadouts in your workshop as is described above, is how it will be on your lines in flight. Further, it really doesn't matter where you locate your bellcrank, fore and aft, due to physics.

That is beyond the scope of this short article, but trust me on this. It is all determined at the leadout guide.

Pushrod guide on Orin's Shoestring keeps the rod from bending. A cotter pink works well as a pushrod guide.

This one's on his profile B Leadout exit. Orin demonstrates checking the yaw left and roll of his Hawg. Basic control-line building By Orin Humphries March A recent issue of Model Aviation had a couple of pictures of models that caught my eye. Leadout exit Another model with a basic problem in the recent issue of MA was a P B In the accompanying photos you can see the pushrod guide on my Shoestring Stunter and a Profile B I built for my son.

Shoestring Again you see my pushrod brace on the aft fuselage. Flying Lines home page This page was upated Feb.

The fuel line is pinched off to prevent fuel loss until the engine is started. You can use 3 or 4 alkaline D cells, wired in parallel positive to positive for a starter battery. Oliver Twist Mk. The airplane is constrained to fly in a circle, which is generally marked. This is one of the oldest perpetual trophies in modeling that is still awarded. Powered by Shopify.

Home Welcome to Control Line Flying. Welcome to Control Line Flying. Model-builders come in all ages and levels of experiences. To help first-time model-plane builders, we have put together some ideas on the first steps you should be taking.

Brodak Mfg. Choosing Your Kit Model airplanes that are built for flying come in two basic styles, The Profile airplane has a flat body, much like the small, balsa wood gliders that have been flown by young boys and girls for many, many years.

The Built-Up Fuselage airplane has a body design similar to the body you would find on a model airplane built for display. The Profile airplane is the best choice for a beginner, for several reasons. First, it is easier and quicker to build. Second, it is easier to learn to fly a Profile-type airplane. And third, a Profile-type is easier to repair. As you select a kit for your first control-line model airplane, look for an outfit that has a.

Remember, when an airplane is traveling faster, you have less time to react and adjust! Also, the. Before You Start Building Once you have picked a kit, we recommend you prepare your work surface. The best work surface is both flat and stable. Purchase a piece of glass that is at least three feet wide, four feet long, and one-quarter inch thick, and a piece of drywall or sheetrock that is the same size.

Place the glass on your work area, and put the drywall sheet on top of the glass. When the drywall becomes covered with glue, paint and holes, it can be easily and economically replaced. Getting Started Once you have purchased a kit and have a work area, we recommend that you do several things before you actually begin building. Read the plans through once to make sure that you have a complete set of plans.

Take all of the pieces out of the box and match them up with the plans, making sure that you have the right number of pieces of each part.

Read the plans thoroughly a number of times to familiarize yourself with everything you are going to be doing. Pay particular attention to any special sequence that the manufacturer recommends in building the model. Make sure that you have on hand all of the materials and tools you might need to build the airplane. Pick one section on which you want to start, then concentrate on that section.

Many of us who have been building these planes for years choose to start working on the wings. Four other tips about the building process: First, always work in a well ventilated area, especially when you are sanding and painting. Second, C-A glue works extremely well in assembling the plane.

Third, Super Coverite fabric is an excellent choice for covering the wings. The fabric is durable and easy to use, and the package includes easy-to-follow instructions. Since the object of building the plane is to learn to fly it, we recommend that you do not put a lot of time into sanding and finishing your early models. The basics of control-line model airplane building can be learned fairly easily.

There are several excellent books available on model-airplane building and finishing. Good luck with your model-building, and welcome to flying the way it was meant to be! View the Brodak Kits. Find a Product. What's Popular. Dope 4 oz.
