1 Aero-lines Volume 1, 2013 News of the Northwest Aeroliners Number 1, March-April Aeroliners in Roseburg By Mark Hansen A dedicated group of N.W. Aeroliners attended the annual fun fly held in Roseburg, Oregon, by the Umpqua Valley Modelers, and headed up by Dave Shrum. Aeroliners present were Ron Anderson, Jim Cameron, and Mark Hansen. It was decided that since the venue was 185 miles from Portland, that Jim and Ron would meet at the home of Aeroliners President, Mark Hansen at 7:30am and Just like clockwork Jim and Ron showed up simultaneously at 7:24am, and wondered what was taking Mark so long. The drive officially began at something like 7:40, and we went pretty much straight though except for a stop at Woodburn for Fuel, and a stop in Cottage Grove for food. The highlight of the trip was seeing the livestock in the fields and listening to Ron complaining about how bad people drive. We arrived around 11am and all the Aeroliners were heard to complain about stiff legs, backs, hips ankles and the lot. Once we got moving, amid the sound of joints popping. We set Aeroliners: Fourth from left, kneeling-- Jim Cameron, behind him standing is-- Mark Hansen, ninth from the left is-- Ron Anderson. This photo was taken at the end of the event and there were a number of flyers missing from this photo. Flying Lines Photo. The Spread was quite good and everyone ate their fill. about packing out gear to the flying site. In Roseburg, they fly at a very nice, beautifully manicured soft ball complex (sort of like what we have here in Portland, but nicer, and not next to a woefully neglected CL circle). So we were told to make sure we don t spill any fuel on the grass and to put cardboard down to keep from killing the grass. As we started to get our pits set up, we were repeatedly greeted by virtually all the Umpqua Valley Modelers, who were anxious to introduce themselves to us. All were smiling;

2 all had nice things to say, and many questions regarding our trip, and aircraft. This is in contrast to the last fun fly the Aeroliners members attended where they were ridiculed for flying too much. Here in Roseburg, after each flight, the person in charge of handing out tickets came over and gave a ticket way with a big smile and never questioned if you ask for 4 or five tickets at once. The entire spirit of the event was to fly as much as possible and enjoy a grand day at the field in early February. There was a rather large spread of food put out, which included hot dogs heated in Wok, chili, chips, cup cakes, cookies, coffee, soft drinks and bottled water. The food spread was not as big as at the last fun fly, but the incredible 40lbs of prizes more than made up for it. Dave Shrum donated most of the prizes and a great deal of them were actually made by him, at one time or another. Included were a number of very well crafted half As and some very nice little field boxes equipped with everything form lines to fuel! Also given away were three Nobler kits, with Fox and McCoy 35s for engines; an Excalibur kit with a wing stared by master modeler Gene The Pits with the Aeroliners planes in the foreground.

Gerald Schamp, and an Enya 45; a Mack the Bipe, with a McCoy 35, a Double Ring Master Kit complete with a Fox 35; a gallon of fuel, and dozens of sets of plans. This is the best laid prize table for any fun fly this author has ever witnessed, and it is owed to Dave Shrum. Also a first for fun flies this year, contestants were allowed to make as many trips to the prize table as they had numbers drawn. The local club and Dave Shrum were all very happy to have prizes won, and they considered it a success of all the loot was off the table when the event was done. This is a very different attitude than that which greeted the Aeroliners at the last event, they attended. The trip home went without a hitch, with a brief stop for food at Casa Baez, in Salem, and there was some crying heard from the back seat of Ron s rig, when Jim Cameron paid to fill up his gas tank in Woodburn, but that was over soon enough. So if you have not been to this event before, make sure to mark it on your calendar for next year, it is not to be missed.

7 The Events Explained: Navy Carrier! By Mark Hansen Control Line Navy Carrier, AMA events , is a group of events with a good balance, between flying skill and building skill. There are three events in the AMA rule book, Profile, Class I, and Class II and three Northwest events, Biplane, Nostalgia, and.15 that are regularly flow, so any dedicated competitor can go to a contest and get a full day of flying in with a minimum of work. The basics for carrier are pretty simple, build a fairly close to scale replica of an actual aircraft that was designated to be aboard an aircraft carrier, fly it off the miniature mock carrier deck, fly seven laps as fast as you can, then do seven laps as slow as you can, then make an arrested landing on the deck. This all sounds easy enough, however it is in actuality very difficult, with the slow speed being particularly challenging. In all AMA carrier events the maximum model weight is four pounds and the pull tests 25G. Or 25 times the weight of the model in pounds, with a maximum pull of 100 pounds! So carrier planes need to be built stout. In the NW events the pull tests are set at fixed maximum, to make the events more beginner friendly. Also, all AMA events require the same length lines, Starting with the most beginner friendly of the events 15. The rules for this event are very simple: The only parts of the pain that can move during the flight are the control system, throttle and hook. No devices that can be deployed during the slow speed flight may be used to increase line tension. Put simply, no line sliders allowed. 15 Carrier Engine: Any of.15 cid or smaller, and in the case of multiple engine models the total displacement of all engines may not exceed.15 Lines: Three lines.012 x52 Plane: any design is legal, no restriction on profile, or full fuselage designs is made. Most however do use profile designs and they have foam wings of the Larry Driskill Half-Lite design. This was a popular 1/2A combat design of the 1980 s which has found new lift in this event. Profile AMA event no. 321 This event was at one time designed to be a beginner event, however with continued competition in the event it is now pretty much flown by full time serious competitors. Here are the basics of the Profile event. Engine:.3661c.i.d. max. Lines: 3x.015 Wing Area: 300 Sq. In. minimum Muffler: May not extend more than three inches from the centerline of the piston. Landing Gear: At least two wheels separated by a minimum of 4 inches. Color Scheme: Painted like a navy carrier craft form of some nation, and with a canopy of contrasting color. Note: Building a scale like plane in the profile event will get you a whopping 10 bonus points. It seems that making a good flying plane for this event would more than outweigh the extra 10 points. N.W. Sport 40 Carrier This event was created by Mike Potter, to use a common engine, on a simple profile plane, and to incorporate speeds that the average (older?) modeler can easily handle. The plane is pretty much the same as in AMA Profile except line sliders are not allowed. Everything else is. The rules only allow for the use of three different engines, the Tower 40, O.S. FP-35 or FP-40 all must have the factory carburetor and muffler. No modifications from stock configuration are allowed to the engine.

8 Engine: Tower 40 or FP 35 or 40 Lines: 3x.015 x 60 Wing Area: 300 Sq. In. Minimum Muffler: Required. Class I AMA event 319: Engine:.4028 c.i.d. maximum Wing area: any Fuselage type: Full Built up type with outlines accurate to +/-5% of scale. Paint: As original Lines: 3x..015 Bonus Points for scale: 100! Line tension increasing devices: Any and all allowed. Rudders, ailerons, flaps, line sliders, shifting fuselage weights Class II AMA event 320 Engine: Wing Area: Any Fuselage type: Full Built up type with outlines accurate to +/-5% of scale. Paint: As original Lines: 3x..018 Bonus Points for scale: 100! Line tension increasing devices: Any and all allowed. Rudders, ailerons, flaps, line sliders, shifting fuselage weights Reworking a Fuel Tank By Jim Cameron This article will outline basically how to take a gas tank apart and then put it back together again. The first question you might ask is why would I want to rework a tank? If you stay in the hobby long enough a project might come your way that requires a tank that is not of standard dimensions. As an example Dave Royer built an old Green Box Nobler and a standard sized tank wouldn t fit so I put together a custom tank for the plane. Another reason to rework tanks is that they are costly. I have picked up old tanks at a swap meet for less than a dollar and then completely overhauled them. Tanks also are subject to vibration and vents can break or become damaged needing replacement. First we must take the tank apart. The tank should be placed into a vise with the back of the tank pointing slightly down. I use a propane torch to heat the back of the tank until the solder flows and use a screw driver to slide it off of the tank. This is the method that I have used for over twenty but it does slightly scorch the finish on the tin of the tank. A heat gun designed for the proper heat range might also be used for this task (I don t have such an item and can t give my opinion). Once I have the first end off I continue to use the torch to take the vents out and the other end off the tank. Now the real work begins. Clean the tank parts. I can t stress this enough, solder will not stick to a dirty surface. I was trained by the Navy to solder electronic components and the projects I worked on were inspected under a microscope. I like using a small wire brush (the ones that are a bit larger than a tooth brush) or 220 grit wet/dry sand paper to clean tank parts. You can take a piece of the sand paper and wrap it around a piece of wood so that you can place more pressure on the parts. I also use lacquer thinner to clean the parts before I start to solder. The better you clean the body of the tank the better the solder will flow around the seams of the tank. You will have to bend the tubing into the shapes needed for the vents which will require soft tubing. I heat the tubing to red hot with the propane torch and let it cool. After the tubing is cool it must be cleaned in the manner referred to above. Some people only heat the tubing in the places which will be bent. I was not taught this way and I always heat the entire length. Vent placement will be dictated by the project that you are working on but, I can give you some ideas that might be helpful. All the vents should be soldered to the tank body in two places at both ends of the tubing. So as an example the fuel pickup tube will be soldered to the outside of the tank body at one end and to the inside of the tank at the other end (usually the back corner). I solder all my vents in this manner because if the vent is not soldered at both ends vibration can cause a brake in the tubing. The top vent (or uniflow line) needs to be above the entire tank (externally) to ensure siphoning doesn t take

9 place and terminate five eights of an inch ahead of the fuel inlet (internally). Designing the vent and bending the tubing to shape is part art and part practice. If the tank parts are clean you are ready to build the tank. I use an 80 watt Weller iron with a three eighths of an inch wedge tip. This iron is great for this application because it is large enough to provide heat to a large surface area which is the key to a good solder joint. I use a non corrosive external flux and a rosin core 50/50 tin/lead solder. At this point some might say that if a rosin core solder is used the external flux is not needed. But, rosin core solder is designed to be used on electronic components which have a much smaller surface area. I start by pre-fitting the front end cap of the tank to the body. You might have to adjust the fit by bending the cap or the body or both in order to get the tightest fit possible. Excessive solder should not be used to compensate for a tight fit. The vents are added next. I use a set of small hemostats to hold the fuel vent to the side of the tank when soldering it to the inside and once that is soldered then solder the other end to the outside of the tank. The other vents are added in a similar manner. Once the first end cap all the vents are soldered in place clean the inside of the tank with lacquer thinner to remove any flux that might be in the tank. When it comes to holding a hot piece of metal in place while you are trying to solder it without moving, you may have to be creative. On one occasion I took a piece of music wire about 4 inches long and bent it in half tightly like a women s bobby pin. This can hold two pieces of tubing together for soldering when each side of the pin is slid up a separate piece of tubing. This comes in handy when soldering the fuel vent to the uniflow vent on the inside of the tank. Wood can be used to hold hot pieces of metal together while soldering. Another trick is to place the iron in the vise leaving your hands free for solder and tank. If anyone has any questions please ask. We are not alone in this modeling field.
