Golden Oldie Floats

R C Modeler's Golden Oldie Floats

Golden Oldie Floats. A Float Design For 5-8 Pound Aircraft, by Fred Reese.

Last month we featured Fred Reese's Golden Oldie vintage type sport biplane for .40-.45 four cycle engines. It flew so well, he added floats. These floats will also work well on other .40-.60 powered aircraft weighing up to eight pounds.
For three years I have been building and flying off of water with a variety of aircraft and float designs. With each new design I learn something new because some new problems occur. One by one the problems would be corrected to make the floats work. During this time I have read and studied everything I could find on float design for both full scale and models. My latest effort is the Golden Oldie, a 56 in vintage type sport biplane using an O.S. FS 40 four cycle engine for power. I had decided that if the Golden Oldie flew as I expected, I would build a set of floats, The airplane flew as well as I hoped, even better. I quickly drew up a set of floats and built them. I called my friend Don Harris at Lake of the Pines and we arranged to fly that weekend.
We taxied the Golden Oldie around for a few minutes to check out the water rudder which turned out to be very effective. I decided it was time to try a take-off and at that point my real education on floats began. What followed was a very long, high speed taxi run. After about a quarter of a mile, the Golden Oldie did lift-off with a lot of elevator coaxing, and after what seemed like an eternity of fancy stick wiggling, it was flying. It was certainly not overpowered, but we both flew it, taking turns, and even managed some loops and rolls. We both liked it, but something had to be done about that take-off.
First, the model was not tracking straight on the water. This required a lot of rudder correction during the take-off. An inspection showed that the floats were not mounted straight. I had anticipated this problem and the mounting method shown on the plan allows for some adjustment. After some adjusting and taxiing, followed by more adjusting and taxiing, we got the model taxiing straight and the take-off's were much easier and a little shorter. Later that day I flipped the model over on the water and got everything wet, so we quit for the day. If you get your four cycle engine wet, be sure to run it afterward at full throttle for about ten minutes to get all of the water out of the crankcase and valve train. Otherwise, remove the backplate and any other covers and warm in an oven until dry and then oil everything.
That night, at home, I checked the float angle relative to the wings. On paper, I had designed the top of the floats to be at 0° relative to the bottom wing, I should qualify for Ken Willard's dum-dum award for following my own plans, as the floats were at least 2° positive, relative to the wing. The engine could not generate enough speed to overcome the extreme amount of rotation necessary to get the wings to flying attitude. A quick cure of the problem was to slip a 3/8 in spacer between each float and the struts. With the floats now at the proper angle, the Golden Oldie would take-off in about three hundred feet.
I wasn't completely happy yet, but it was flying and taking-off consistently. Still, the model was sensitive to rudder corrections during take-off and several times while making a second take-off during a flight, the model would be unstable at lift-off. When I dumped the biplane in the water a couple of times, Don laughed at my fumble-thumbs until it happened to him. The airplane was acting tail heavy, but that seemed improbable to me as the Golden Oldie on wheels was slightly nose heavy and very stable. I hadn't rechecked the CG location on floats relative to the wheeled CG position. It then occurred to me that the wheeled landing gear weighs thirteen ounces and is positioned several inches ahead of the CG. The floats are only slightly heavier forward of the step and do not compensate for the heavier wheels. I screwed some weights to the nose of each float and the stability problem was cured. Before, with a full tank of fuel, the CG was far enough forward for the model to be stable, but later as some of the fuel burned off, the CG shifted rearward and the stability became marginal. With the model properly balanced it is a real pleasure to fly, but I still felt the take-off run could be improved.
During one of our flying sessions at the lake, Eut Tileston visited us. Eut has designed full scale seaplanes and his R/C floats are excellent, so I listened to his suggestions. He told me that the rudder sensitivity during take-off would be helped by moving the float step rearward a little. Now I realized that a re-design of my floats was necessary. I wanted to change the angle of the forward keel so that the float bottom just ahead of the step would also be at 0° relative to the wing. I felt that the new float bottom would cause less drag on the water. Every little bit of drag is critical on a low powered float plane. Thrust must overcome drag to reach flight speed, the more drag, the longer the take-off run. Most R/C models have the extra power to quickly reach flight speed, so float design becomes less critical with increased power.

The step was moved back 1-1/4 in to reduce the steering sensitivity. I also increased the angle of the rear portion of the floats and deepened the step for easier rotation at lift-off. Three-quarter ounce weights were glued into the nose of each float to adjust the CG. We tried several different propellers, but an 11/6 Zinger seemed to work best. The result of the changes is that the Golden Oldie will now take-off in less than one hundred feet.
This has been a very interesting learning experience for me and I am very satisfied with the results.
Construction. Cut out the bulkheads from light 1/8 x 3 in balsa. I made a little miter box from 1/4 in square balsa and a scrap piece of plywood. All of the bulkhead side angle cuts and bottom angle cuts are the same. The miter box simplifies cutting out the bulkheads and makes the parts more accurate. Lay the 1/4 x 3 in balsa top over the plan and mark the centerline and the bulkhead locations. Glue the bulkheads to the top. Cut out the 1/8 balsa sides and bevel the top edge and glue to the bulkheads and top. The sides will have to be pulled in at the front and the top pulled down slightly to meet the sides at the front. My original floats are not pulled in at the front and they do not look as nice as the plan floats.

Member Profile for André

Hello!

I'm André Costa (Brazil), I build and fly model airplanes since
1968 (F/F, UC). At 1974 I ingressed in RC, my first radio, was a Logictrol 3 ch, the engine was OSmax 25 rc and Falcon 56.
In the 80's I build varied scale model airplanes. In 1985 I started the construction of a experimental ultra-light airplane in wood, which flew sucessfull in 1991. Currently, I dedicate to the research of inventive solutions for light electric models.
With my son Geraldo, I’m editing plan’s for you!
Best regard

Terms of Service.
Please read the Plans Printing Service Terms of Use before placing an order.

What are you ordering:

You are ordering a print from the main PDF file in this listing, it´s exactly like taking this file in a thumb drive to a local print shop and ask them to make a print.

About the plan source:

You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling. To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.
In doubt please ask us for an opinion.

Plans Scaling:

We can scale this plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.

You will receive:

  • Laser Printed plan on good quality Bond paper or/and Tracing Paper and/or Polyester sheet of the PDF file from this listing, depending on what you have purchased.
  • Rolled sheets, up to 5 in the same cardboard tube.
  • Envelope, up to 5 sheets per envelope.
  • Articles and Instructions if they are available and if you order them.
  • Air Mail, Priority, Priority Insured or Normal mail, according to your choice.

About our printers:

We use professional quality laser OCÉ and Canon printers/copiers, these printers use toner, not ink so the printings will be durable and waterproof.

About the different media types:

Bond Paper: White Bond paper, 80 grams per square meter.
Bond Tracing paper: Bond Tracing paper, 90 grams per square meter.
Polyester film: High quality polyester sheet incredibly durable, will resist cuts and glue and can be washed (I use it as sail material on my RC sailboats).

Pricing:

We charge by print length (914mm or 91,4cm or 36in. by the length of the print)
This means that a plan 120cm by 150cm will be charged two times 150cm because it will be printed in two tiles, a plan 91cm by 150cm will be charged one time its length or 150cm and a plan 91cm by 40cm will be charged 40cm.
The system will try to fit a plan in the 91,4cm of the printer width in order to reduce the costs or print length to the maximum. This is the same charging method used in any printshop.

3D Printed Parts
Order 3D Printed Parts for the Golden Oldie Floats

General Information

3D printing allow us to design not only complete airplane models but also parts to complete balsa, foam or even composite model airplanes.

Parts can be designed and printed to fit exactly a model you have or a model you plan to build, even if you are not building this model to the full size plan.

3D Printing, and 3D CAD allow us to create the actual parts to fit on our models but also allow us to create negative molds where we can make composite parts.

I´m adding this service to all the plan listings on the site knowing that not every part you imagine or need can be done, knowing this, jobs will be evaluated case by case and a price estimate will be given on request.

What can be done with 3D Printing:

  • Canopies
  • Cowls
  • Wheel Pants
  • Landing Gears
  • Wing Ribs
  • Motor Mounts
  • Servo Trays
  • Servo Covers
  • Wings
  • Fuselages
  • Complete Models

Full Models, Wings or Fuselages

It is possible to design a complete model for you but keep in mind that this is a lengthy process, many hours are needed to design and test a fully 3D Printed model. The finished model cannot have the same internal structure of the wooden made counterpart because it wouldn´t be possible to print it, it would have to have a structure like the models you can see in the 3D Printed Kits section of the site.

From the outside they are very loyal to the plan but still they have to be printed in sections, typically to fit a 250X210X200 mm cube that is the printer maximum build volume.

3D Printed planes are also heavier than light balsa models, all built up and ready to fly, with an electric power system they are generally a little lighter than the same model if it were powered by a glow engine. Please have a look at the 3D Printed kits section to have an idea on this.

Pricing

I will calculate a price upon request, please contact me here mentioning this PlanID: 97972 and the job you wish me to do.
