Aeromodelling

Aeromodelling is an art of craftmanship in designing and construction small scale aircrafts very close look alike the real one. It is interesting subject to explore that can be treated as a hobby for a life time. Beside the craftmanship, a basic aerodynamic principals are applied to the construction including mechanicals and electronics if a model need to be airborne.

One who likes to get involve with aeromodelling can always purchase an ARF (almost ready to fly) models including radio and accessories to start with, learning the technique in assembling and flying. There are no limit in aeromodelling but the real satisfaction is to design your own model that can be flown successfully.

The basic rule for a model plane able to fly is that it must be as light as possible and with strength. Various type of light weight woods can be use for the construction of the wing and fuselage. The art of gluing the woods together provide strength.

In order for the model plane to fly, some electronic gadgets are incorporated into it for controlling the power plant throttle, aileron, rudder and the elevator. A radio is use to communicate between the model and the pilot.
There are various kinds of model planes that can be constructed such as glider, trainer, warbird and pattern plane. These type of planes have different characteristics that suit in different environments. The power plant can be either from glow, gasoline engine or electric powered brushless motor operated from lithium polymer batteries.
In the US and Europe, dedicated fields are available for flying Radio Control (RC) models. So, it is much safer for the flyers without having to worry about accidents that can occurs to the public. Here, in Malaysia, I dont think we have any proper field despite having request to have one. So, the flyers sort in flying their model in an open construction field with worries in crashing to the surrounding public properties.
Accidents can always happen by pilot error, mechanical and electronic malfunction. Pilot error means, lost control due to wrong orientation. Mechanical failure can be caused by the construction of the model. Electronic failure can be caused by radio gliches, interference and components malfunction. Although before flying the model have been throughly checked but accidents can always happen for some reasons.

The above explaination is just a summary. There are a lot of factors needed to know in the design and construction. Through communication with aeromodellers one can be an expertise in this trade.
