Modelling Glossary

For many years I have been wanting to write a series of articles on house building, but that never fully panned out turns out it’s quite time consuming (the house building too). Stuff like waste management (garbage and recycling), water security and off grid Solar in an urban area for many years, but the more and more I read articles from people supposed having done it, the more I realize how many people write stuff that they haven’t done considered or even have any experience of it or in it.

What I can save is with everything that is written “Caveat Emptor”. I will also state clearly upfront that I am no professional builder, electrician or plumber, but having essentially rebuilt my own home, including  re-wiring, re-plumbing, off gird back-up water supply and recently having had a full PV solar system installed according to my design and specification. I can confidently say in my situation I know what I am talking about and I what I wanted to achieve… And I have succeeded in many ways more then I expected.

And no I am not some sort of Eco-warrior with pent-up anger, that still buys stuff with plastic wrappers… And Everything is doable since I have done it!

With there being so many adhesives on the market which is the correct one for me to use?

Here is a basic list of adhesives, and while there are more you certainly don’t need everything one reads about to get a plane in the air. There are no right or wrong answers here just differing applications, right tool for the right job

  • ACETONE – ABS plastics take some off cuts dissolve it in acetone so it makes a paste like toothpaste, glue your ABS plastics together with this mixture, it will weld/ fuse the two parts together you can tack glue it with Thick CA if you don’t want to masking tape it together.
  • ALIPHATIC Resin – for surface where you will be sanding down use ALIPHATIC RESIN – ALCOLIN PROFESSIONAL it’s the only aliphatic resin on the Market in South Africa, I am aware of but there will be definitely others overseas. Check one of my previous posts there is a picture there, want to see the results check MAD’s build. Joining wing sheeting, stringers, i.e.: any place where you will be sanding down and covering
  • CA – use CA, for it for taking or places where you need to glue things together fast and soak the wood for a better bond. You could glue your entire plane together with it but its expensive and nasty if inhaled too much. CA goes brittle when used with accelerator directly, trial fit your joint spray accelerator on wait a minute or two minute then put on the CA, you be surprised how good a joint this makes and crack free no brittle. Use it for repairing Fiberglass cowls (with Micro balloons), joining ABS plastics

So what do all these terms mean, hopefully we can dispel myth and confusion here. I will try to give the international meanings and terminology. This is an organic list which will grow with the site

  • Anhedral: This is the opposite of dihedral. When a model is viewed from the front, the downward angle of wing tips from the center to the wing tip is anhedral. This makes for a less stable but more maneuverable aircraft.
  • Incidence: This is a wings angle attack relative to the fuselages center line or Longitudinal axis. By the setting a positive incidence, it  allows the aircraft to sit flat when in straight and level flight. A modeller will usually use an incidence meter to set and check the angles of the wing and horizontal stabiliser. Robart makes an excellent jeweled movement incidence meter.
  • Scale: Scale in modeller terms has two meanings:
    • Aircraft scale; i.e.: 1/5th scale, this is the size in relation to the real deal. In this case it’s one fifth the size of the real aircraft. This can be displayed on the plan as 1:5 or similar. On the model plan, 10mm would be conversely equal to 50mm on the real aircraft.
    • Scale or Sport scale: this refers to whether an aircraft accurately follows or closely follows the correct proportions, locations and details of the real plane. E.g.: A great way to enhance a plane is a scale cockpit. This Means the cockpit should closely or be identical to the real aircraft, although the rest of the aircraft maybe sport scale, to enhance the aircraft’s flying capabilities
