Call Tad at Goldenwest models. He was making Hotspots for a while, don't know if he still is. 661-250-8542.
His stuff is first rate. He built my Hotspot, finished to look exactly like the original Jet Team Liebetrau demonstrator.
To give you an idea of what this guy can do, check out his B1 project (and all the other stuff in his shop)
