Corpus Christi Larry uses internally connected lines Slow Rats fliers area Larry has suffered through enough tirades about safety general evils internally con nected lines particular have come up simple yet effective way ease strain control lines exit wing tip Larry takes three- four-inch length very small diameter teflon tube can buy dispensing Hot Stuff slips control lines through before makes up line ends connection inside plane teflon tubing adjusted covers control lines emerge wing tip thus protecting abra sion against tip guide also making very much harder kink very vulnerable spot Larry relates getting 018 lines through teflon Hot Stuff tubing takes little care results terms smoother safer controls worth effort Fuel Tanks last column dedicated analysis fuel tank sys tems work way what expect particular type sys tem couple additional points need made First uniflow style tank will exhibit its normal characteristics pressure fuel system discussion last column talked about tanks vented atmospheric pressure reality thing important pres sure differences fact see no reason chicken-hopper arrangement would work pressure fuel system al though have never tried system type Second show hopper tank chicken-hopper style set-up normally vented tank also see no reason couldnt small uniflow tank too However dont think would gain very much since fuel level hopper going remain very near level bottom bleed tube once tank pressures get equilibrium So far have several comments fliers have read last column general have quite com plimentary comment really hurt Last weekend Houston contest speed fliers came over said enjoyed column said though old well known formation felt good get print once Oh hurt may have old stuff him Ill guarantee didnt know stuff before started research column Oh well guess left-handed compliment better no compliment years building flying competing old well-known information just completely passed Another point Go back June issue Model Aviation re-read column Don Jehlik fuel tanks Somebody tell famous famous Stockton Chicken Hopper tank chicken hopper merely uniflow tank still another point racing model speed plane vertical placement air bleed tank uniflow tank virtually no significance contrary popular opinion air bleed must near fuel pickup possible stop think forces operation flight find centrifugal force very much greater force gravity like factor 12 15 20 real critical consideration placement bleed out relation needle valve hole along line perpendicular flight path Additionally placement front-to-back tank no conse quence since no acceleration direction once plane has accelerated speed Again significant con sideration bleed located relative flight path Something else consider should fuel pickup placed tank insist placing pickup clear back tank may outermost point tank flight immediately think long tapered cylindrical tanks use very Rats pickup back tank look tanks imagine outermost point tank Rat flight youll see outer point probably right front tank diameter order inch quarter back tank diameter may half inch Maybe someone can tell tanks work really Maybe story need 6- 7- ounce fuel tanks comes
