Hi, I've been lurking long enough and want to build myself one of these blimps. First step is buying the envelope and gondola. I saw that earlier versions used the Plantraco but the newer version uses the Tri-Turbo model off the shark.
The shark seems to be sold out at the linked place, I've googled around a bit and mostly found envelopes for the Tri-Turbo, but no gondolas or complete setups. Has anyone found them anywhere? Should I just get a Plantraco, why was it not used in the recent version?
