original intent Navy Carrier event model conventional fixed-wing carrierbased naval aircraft NCAC interpretation approved CLCB would limit CL Navy Carrier models conforming configuration Specifically NCAC request would add paragraph 3 Aircraft Requirements following interpretation Models must heavier-than-air fixed-wing configuration Autogiros helicopters other aircraft rotate propellers horizontal plane act rotors hovering flight specifically prohibited reasoning behind NCAC request follows Rotary-wing other non conventional aircraft specifically described rules currently exist leaving room wide variety interpretation applying rules such aircraft Such variance interpretation has already resulted protest before CLCB interpretation clarifies rules specifically prohibiting such

intent rules ughout existence r rotary-wing models considered original intent event rules would have written accommodate rules obviously written rotary-wing models mind Because portion score based low-speed flight performance rotarywing other aircraft capable hover would have advantage could overcome conventional models Allowing such models would obsolete existing equipment Nats Nationals history another year fortunate enough attend saw some outstanding Carrier flying Excellent conditions combined good fortune produce some very close competition quite few personal best performances Joe

cubic inches Carrier Combat competition Charles Knapke Hobby Shack has helpful working manufacturer Thunder Tiger Model Company apparently no interest producing second smaller engine same displacement class ylonlHager Continued paqe 128 right air bubble should larger -inch diameter After practice might find way works better secret avoid injecting air during fueling Operation Make sure have prop turns least 23500 rpm ground may go up down later start high side Start engine rich side lean engine slowly about 15-20 seconds l peak reached Immediately start back up engine same pace until rpm drops back least 1000 first flight possible far have engine drop off pipe Finding peak very important may need run engine once make sure know before fly test needle system anyway Peak characterized engine rpm flattening out screw needle often picks up 200-400 open back up After get needle set engine should remain set least 15 seconds engine may have heated up properly unfortunately may have too hot Inspect plug hint what wrong should able heat engine up thoroughly still have good plug Sometimes wire will break smooth shiny engine overheating during warm-up Shim head 002 inches increase rpm try again After get air listen carefully engine going lean first few fights least 1200 down peak ld stay rich watch out youll having heating problems future Potential cures larger efficient cowl openings head clearance smaller props course less nitro best solution will lose power cant seem get engine lean enough try lowering tank about 1A inch beauty fuel system have working system airplane eliminate variables except engine am always glad pass information have something think would interest others please send See next month Model Aviation *
