L0 OVOO7O RADIO ____ ___CONTROL Ron Van Putte 111 Sleepy Oaks Rd Ft Walton Beach FL 32548 THE SPORTSMAN rules change snafu over RC Aerobatics Contest Board voted accept proposal add three turnaround maneuvers existing schedule hope saw news Focus Competition section June issue Clair Sieverling Phoenix AZ sent letter response Eric Hawkinsons letter published comments April column already responded similar discussion Don Lowe column November 1991 Radio Control Modeler Don published Clair s response April column long short Clair offers alternative way level field managing two-stroke versus four-stroke engines Pattern competition give 5% bonus fliers using two-stroke engines 5% penalty using four-stroke 120 engines pointed out since early four-stroke engines inferior two-stroke ones given displacement waiver make up lack power encourage development four-stroke Pattern engines objective overachieved Todays four-stroke 1 20-cu-in engines make much potent Pattern engines piped 060 two-strokers Clair thinks its time level field again According Clair 5% bonus penalty would amount 50 points 1000-point roundenough make 120 user ponder somewhat since usually less 50 points between first second third places normal competitive round flying would hazard guess extra power etc 120 may worth nearly 50 points per flight over 61 engine concept lets 120 pilot continue use preference game would little equal pilot prefers piped 61 can continue use equipment prefers has equal chance pilot skill alone will determine outcome No manufacturers end up obsolete engines fuselage molds wont have million dollars worth Pattern planes suddenly plummeting sport plane prices over country like idea have written Clair inquire whether plans submit rules change proposal implement does Ill support doesnt Ill submit myself have summer see 5% bonus penalty would affect outcome contests around country course such rules change proposal would affect AMA classes Being governed own rules FAI members would immune Since RC Aerobatics Contest Board members FAI fliers Im concerned may perceive such rules change proposal potential threat down road other words may fear rules change would eventually work its way class would interesting compare votes see board members use four-stroke engines vote proposal 42 Model Aviation Charles Norriss Wesley Chapel FL R/C City Eclipse uses VS 60 long-stroke
