Fast or several RC aircraft enthusiasts who dream of their favorite size replica holes in the sky. But it will not be easy to copy only the exact size of the aircraft in full screen and then minimize it, what you want, for example scale ¼ 8.1 scale so on and so forth. Even if you think you are using the CAD software to design and develop the plan, who know, without regard to principles of aerodynamics, you do not have a stable airplane. So the first step on how to fly model aircraft. It will be impossible to fly your model airplane, without regard to the aerodynamic design. Again, before starting to build and fly your very first test model, you should already develop your skills, at least a moderate level. Importance of a non-flying scale model aircraft wing shoulder design. Then select the type of coach-size model, the 150 or Cessna airplane Piper Cub J3.

At least the planes are equipped with the design stability. The wings of constant chord and rectangular (with Piper Cub J3). Mecca wing, ie the wing above the fuselage, having the stability of the pendulum. tricycle landing gear type (Cessna 150). But wait, this means that stability is the same, if you choose to scale these devices? The answer is “No” These aircraft are terrible when you resize and copy the exact dimensions. As I mentioned earlier, the aerodynamic design should be considered. This phenomenon is known as “The scale effect”. We can not measure the air molecules and the viscosity of air. The behavior will be different. The position of the wings and wing area, area of the horizontal stabilizer and vertical location, aerodynamic design plays an important role for stability.

The redesign of the aircraft is essential. The model must be rethought on the basis of coefficients of lift and drag and the Reynolds number on his mini-size, to ensure stability. Therefore, some almost ready to fly, ready to fly kits or 30% or 40% level specification. Meaning that 30% has been copied from the plan in large format. Perhaps the area of the tail has been changed or drift. Changing surface type wings or wings. In order to achieve stability. The closest in size from full size aircraft, the more you can copy the exact size and behavior. Consequently, ¼ model aircraft are popular this really serious RC model airplanes. Given the cost and implementation, risk to life and property, it is possible for those who were well to do. Imagine how many gallons of fuel is consumed! You’ll also need more airfield. Well, the engines of gas or oil (chainsaw engines) into these monsters that costs should be used for fuel reduction. Other than using methanol, castor oil and nitro methane fuel for engines warming up.

So before that not all expectations on the purchase of one, the facts first.
