Hi
These are tips to make a good plane.


Balancing the aircraft

Balncing is very important in order to make your plane fly. If the tail of the plane is heavier than the nose the plane will stall.and if the nose is heavier the plane will fall.but if you hold the plane from the CG (centere of gravity usually located under the wings) point and the plane is properly balanced the plane will fly smoothly.


The dihederal brace

It is also important to give an accurate dihederal brace. the peice called the dihederal brace should be cemented to the wings very firmly. an inaccurate dihederal brace would result in an immbalanced flight. But some planes dont need a dihederal brace so you needn't worry for those planes.


Shaping the aerofoil

In some plane you only get a long peice of balsa wood for the wings. In those type of plane you have to sand the wing in an aerofoil shape. for a flat bottom wing the bottom surface of the wing should be left flat and on the top of the wing draw two lines lengthwise with a pencil, so that the wing is divided into three equal parts. make the trailing edge very thin and sand so that when you place a level object across the wing the object lies flat from the line near the leading edge to the trailing edge. Then round off the leading edge leaving a perfect aerofoil shape.

Pre-flight tests

These steps are to be taken on all types of model planes.

1)Check the balancing
2)Throw it without powering it by any meansand see that it flies level and comes back to ground smoothly
3)Match all its dimensions with the plan

This is for R/c planes
1)Check the controls and see if they are ok
2)Take off
