Control Line: Navy Carrier

CONTROL LINE NAVY CARRIER BY NOW YOU MAY have read two proposed rules changes Control Line Navy Carrier events passed initial Control Line Contest Board ballot As read cross proposal deadline July 15 should imminent expect cross proposals change would allow additional minute starting time additional engine proposal would shorten current allowance two minutes per engine passed earlier year urgent proposal However proposal allow two-line control systems Profile Carrier probably will see cross proposal As originally proposed change would mandate Class II line diameters one- two-line systems Profile Carrier seems inappropriate handicap Profile models such large lines Because electronic control system throttle would have weight penalty compared traditional three-line control system smaller line sizes Class seem appropriate should no significant advantage using two-line system Profile Carrier since intent event encourage simpler models Some fliers consider electronic throttle controls additional complication although use tend agree smaller lines reduce line drag compared three-line system Using Class II line sizes 024 diameter would provide drag disadvantage addition weight required servo battery Using 020 lines standard cable dimension 021 diameter would allow line drag reduction offset weight throttle control system ignores differences line roughness Reynolds number other factors easily accurately accommodated line varying airspeed throughout its entire length reduction line drag proportional reduction line diameter Using two 020 lines compared three 015 lines would result reduction line drag bit 12% excluding effect insulation required lines carrying electrical signal dealing small highly streamlined Speed models reduction would significant Line drag Speed model can contribute half total drag much larger much dirtier Carrier models believe line drag closer 20-35% total drag standard three-line configuration lower line-drag contributions reduction 12% produces reduction total drag 25-43% resulting high-speed advantage typical Profile Carrier model would about 1 mph Using 021 cable rather 020 solid lines would cut advantage almost half Adding insulation lines weight model likely puts electronic throttle control disadvantage heavier faster Class II model advantage twoline control system might worth considering would like try can contact
