The instructions

Finally

Perhaps, this is the best one I made. I am using a whole 50gsm A4 paper.

It come back to me once i throw out by horizontal and looping.

Nearly done

Using the normal A4 printing paper, but it seems to heavy and can't turn for a complete circle.

So I have try to make a smaller vision and also using a 50gsm A4 paper,

but still can fly a perfect circle.

way to record the flight path

Playing with different making type and material but it do not fly very good.

Research for more flight's design. I think this help a lot for designing the flight.

Trying out a different way to make paper flight. This time is not fold a normal A4 printing paper 

but using a heavy card and make it as a puzzle. However, it still not reaching my target.

The problem is too heavy.
