Hi Charles, Well, keep in mind I still had sight when I was into model rockets, but the kits usually weren't that difficult to build. Of course, how difficult the kit was to build depended on the kit. They ranged from beginner models for kids to very advanced models for adults. The models I built were mostly the beginner models as I was only 9 or 10 years old at the time and the instructions were not that difficult.
However, I do remember my dad and I did buy one of the more advanced kits, the Apollo 11, and that one required my dad's help because it was a fairly detailed replication of the Saturn 5 rocket and Apollo 11 command module.It had to be painted, glued together, and there were several detailed decals to add to it. I suppose I could have done that one myself, as I was sighted at the time, but couldn't have done that one blind as we wanted it to look as close as possible to the real thing. As far as the fuel goes the model rockets use a solid rocket engine meaning that it uses a special propellant that comes with the engine you buy from the toy store. The fuel and oxidizer are mixed together into a propellant that is packed into a solid cylinder which comes inside the model rocket engine itself. You use an electric ignition to light the engine, and launch the model rocket into the air. Once you use the engine you have to replace it before relaunching the model rocket as there is no way to refuel it. That's why model rocket engines generally come three to a pack as you can only use them once before throwing them away and buying a new one. The reason why modern model rockets use solid propellant rather than liquid fuels like gas is for safety reasons. Apparently, back in the 60's when model rockets first became really popular kids had a habit of blowing their hands and arms off messing with liquid fuels like gas. So modern model rocket engines use the same type of solid propellant the shuttle uses in its solid rocket boosters but only on a smaller scale of course. You just install the engine, set your rocket on the launch pad, connect the electric ignition and blast off. There isn't any handling flammable materials, poisonous chemicals, or anything too dangerous for a kid to get hurt with. Just remember to stand back before igniting the engine as you could get toasted if you are too close. As far as a blind person building and flying model rockets I think the blindness issue takes a lot of the fun out of it. The most fun I had with them was launching them and watching them reach maximum altitude, say 1,000 feet, and then descend back to the earth. Not being able to watch them fly takes most if not all of the fun out of it. At least for me that's been the reason I haven't gotten back into it. For example, back around Easter time my in-laws had a couple of model rockets they decided to launch after dinner and everyone sat outside watching the rockets go up one after another. I felt really left out of the experience because I could hear them take off, and had to listen to people ooh and ah as they flew overhead. One even crash landed right in the middle of the pond and we couldn't get it until summer when someone finally went swimming and retrieved it out of the mud. By that time it was pretty much hosed. In any case I didn't really feel connected to the fun of watching them. Being told a rocket just torpedoed straight into the middle of the pond isn't quite as fun as watching it hit, break apart, and sink. Cheers!
