parts flying objects earlier free flight designs successfully eliminated horizontal tail vertical tail immortal last words Otto Lilienthal sacrifices must made Thing efficient incredibly quick simple build alot fun fly Unfortunately vertical tail has reappeared tried make go away needed someplace hang rudder first version Thing design Bill Potter design appeared Tenderfoot section December 1972 American Aircraft Modeler original Thing finless wingless lifting body about five inches long made solid sheet balsa cheap built out cardboard did fly albeit inefficiently sufficiently rugged hard time destroying After building original Thing moved other models forgotten concept re-emerged discussion some coworkers about neat flying objects built kids recalled Thing tried recreate memory soon file-folder cardboard version flying between cubicles engineering offices major aerospace corporation will name company some friends still work office-Thing got thinking about concept again built stick-andtissue free flight Thing powered ancient reed-valve 020 free flight Thing still great small-field sport model Since comes down almost fast goes up can use long motor run get model quite high still lose RC Thing presented article could easily converted free flight simply deleting radio gluing control surfaces right positions inevitable next stage Thing obsession would radio-controlled version simple enough model impossible resist temptation build just see what would After its hard find quicker-to-build model no wings no curved parts allThe entire model assembly straight sticks
