type models enjoyed much before going service wanted laid-back type flying enjoyed past Texaco earliest events flown under new banner restriction models designed flown before 1939 left modelers very large airplanes build fly later creation 1/2A Texaco allowed modelers scale down humongous air planes sizes suitable Cox 049 engines last SAM Champs Texaco popular event 60 entries sec ond popular
