Don't know if it is this or another: [link=http://www.ebay.com/itm/181120692913]E-Bay - Athearn Convair POGO C/L VTOL.....w/box[/link]
These are collector items and somewhat pricey. I'd think it would be neat for someone to model one of sufficient size to mimic the motions of the Bi-Slob CL "3D"
bipe. That would be kind of fun, actually. Launch in VTO mode, hover, engage in horizontal flight, loop, back to vertical hover, etc.
