This is my first Cardboard Flying Body project. Actually it finished like a model with kind of delta wings, but all started with an eggs cardboard package and another simple cardboard box
Step 1: Beginning
I took the lid of the eggs cardboard package, put glue on the edges and than I banded it and fixed it with paper tape (not shpowed) in a position until it glued. Than I took a simple cardboard box (first that was by the hand - there is always some of these, different kind and sizes, in the house due to lot of food and any other necessity), opened it on one end and made some cuts to have a kind of holders of the first part. Essentially, first part came to second like a head. This was basically the "airframe".
Step 2: Wings, Vertical and Horizontal Tail Stabilizers
All this parts are made of typical cardboard from boxes, glued and fixed with paper tape. Here are photo's from different angles. On the wings, I made ailerons and flaps by simply cutting with scissors, little into the wing. Then I bend this parts up and down, and this works; you can fix this surfaces in different positions to tune and correct model's flight.
Step 3: Cutting Wings in "delta" Shape
Next I added tail horizontal surfaces, made from the same cardboard as the rest - photo's from different angles.
And finally, I put some colors on. This happen in another city where modeling exhibition and competition was getting place. Unfortunately KFB-1 was not flying because it was given like a present to one child. What happen after I do not know, but important is that one child was happy for a moment.
We have a be nice policy.
