I have made many things out of fiberglass over the years. Typically, my projects involve building a plug, making a mold from that plug and finally using that mold to make pieces.
One project that I have wanted to do for a while was inspired by a ceiling fan that I first saw years ago. I am sure that you have seen the fans that look like the nose of a WW II fighter plane. From the moment that I saw that fan, I thought that it would be cool to have a helicopter body that would hang from the underside of the ceiling fan making the fan blades look like rotor blades. Of course the helicopter would have to be a classic – I chose the UH-1 from the Vietnam era.
Thus the project begins. The first thing I like to do when I am building something like this is to go to the hobby store and pick up a model of the helicopter that I want to build. I use this model as a three dimensional reference. While 3D references are not always available, I do like to use them when possible. For this project, I selected a 1/35 scale UH-1. Using this model, I can get a good idea of the size that the fuselage has to be relative to the diameter of the fan blades in order to maintain a scale appearance.
I begin to build the fuselage of the model and to analyze the proportions, angles and curves of the copter.
At this point, I can begin to produce profile drawings of the copter. I definitely need to start with a view from the top and a view from the side.
Some of this is accomplished through artistic ability and some of it is cheating. The model that I bought had these views in the painting instructions. Based on the diameter of the fan blades, I figured that the fuselage should be about 40 inches from nose to tail. I simply used my copier to blow these views up to the size that I need. Then I drew in some details that were lost in the enlarging process.
