RE: Building a Blimp
Ok terminology I use
Airship = dirigible = French term for steerable balloon
Airships and dirigible come in three forms:
Rigid, trademarked as zeppelins, have a solid frame that encloses separate gas bags
Semi rigid, one big gasbag that has at least a ridged keel, possibly a nose or tail cap to hold fins.
Non rigid = a blimp. Just a gasbag that is kept taught by internal gas pressure.
The point that I was trying to make is to make a successful smaller RC airship, it is easier to make a blimp than a rigid one (A zeppelin), because in the model the frame that gives it its shape is dead weight. I didnâ€™t mean to imply that a model of the Hindenburg should be an inflated bag, just that replicating the scale is more of a challenge.
