Let’s first start this topic with Type of wood and there Substitutes, for the main reason there are loads of different woods we can use in modelling and depending where you are in the world, the names may differ but the wood is still the same.
So not all of the time can we get the wood we need like Spruce for example, or it just because it costs an arm and a leg. But here are some useful substitutes in my opinion
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.
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
