I know the proportionality relation (regarding measurments) between wing span &horizontail stabiliser, wing span & veritcal stab,wing span& fuselage lenght.......... but i am confused with selection of wing span ??? ,i want to build rc plane of weight less than 500gms,
I am using thermocol for wing and coro plastic material for fuselage......
so, help me regarding selection of wing span and chord lenght which can lift my rcplane..........:help:

thank you sir :) , but I want to know how to choose wing span ,chord lenght ,thickness of my airfiol ???,so that it has a good lift (weight around 600gms of total rc plane)
how can we calculate the lenght of fuselage if we know wingspan?
Perhaps the link below might help you.
I would pick a known RC model airplane and use its information when designing my own for the first time
https://www.radiocontrolinfo.com/rc-calculators/rc-airplane-design-calculator/
or get this book :

Good luck to you

it is the wing area, or the wing loading that you are after.
try this :

Many others are trying to figure out the answers similar to your question:

Hii, my views is, dont design own plane, try to download plans and then built it. As these plans are already made by some experts. U can design ur model own, but it didnt fly very well and doesnot have any good flying characteristics. Rest is ur choice.

Agreed. good recommendation. Leave the design after you are well versed in RC flying.
Yes, dear i have many plans in pdf format. All are designed by professionals. I have trainer plans also made from depron.
If you are building one of your own design , this link might help

A little bit of disagreement here. IMHO, the degree of learning goes in decending order like this,
5. Build a plane from scratch using the thumbrule
4. Build a plane from plans
3. Build a plane from Kit
2. Build a plane from arf
1. Buy a PNF and fly
Each degrees of going up teaches us something that we cannot unlearn forever. and while we get comfortable with lower levels, we hardly bother to move upwards for many reason. so i suggest to build a plane from scratch using just the thumb rules and it may not fly good at first or at all. However it will teach you things which will never allow you to make the mistakes.
check this post here: http://www.rcindia.org/rc-locations-and-clubs/where-to-fly-in-chennai/msg172539/#msg172539
Ive been building and flying planes using this for years and things never go wrong. To add more, this will help you even if you are flying a ARF [plane to check things to avoid a grave crash.

Interesting view point.
May I offer a different view?
Suppose you wanted to learn to ride. Would you start with:
1. A Harley
2. A Bullet
3. A Hero Honda
4. A Scooty
5. A bicycle?
Next, let's suppose all you wanted was to learn to ride a bicycle. Would you:
5. Build it from scratch using the thumbrule
4. Build it from plans
3. Build it from a Kit
2. Assemble it
1. Buy a ready made one?
So perhaps it depends on what you are trying to achieve. The two extremes of which are:
1. Learning to fly RC quickly, safely without bothering much about the fundamentals, or expense
2. Learning the basics and progressing step by step to RC with least wasted expenditure
To each his own, I guess.
