Rotary engines hold a special place in all of our hearts. The sound is unlike ANY other engine (If you don't know what we're talking about, go to YouTube and search Gnome 160). These engines are extremely rare, but you can still see them installed on flying replicas at museums such as the Old Rhinebeck Aerodrome, the Golden Age Air Museum and the Fantasy of Flight museum. Our Keep 'Em Spinning T-Shirt is an ode to these rotary engines that were a crucial part of WW1 aircraft and the appreciated efforts of anyone who has dedicated time to keep these rare gems still running.
