Since makes sense try Inside Loops before Out side Loops Ill discuss both month starting Inside Loops maneuvers require straight level entry Fliers usually dont have difficulty setting up Inside Loops however some have tendency have airplane climbing slightly Try get good flat entry respect horizon Re member also wing lower other airplane will pull off direction low wing making loops corkscrew Get wings level maneuver entry youll save yourself trouble trying correct corkscrewing airplane Assuming entry set up properly re ready pull back stick initiate loop size loop function far pull back stick sensitive airplane elevator control input try set up airplane use almost elevator stick movement loop usually provides sufficient elevator control rest maneuvers use dual rate elevator switch give normal elevator throw Low-rate switch position use High-rate switch posi tion setting up Three-Turn Spin Master-class fliers also use High-rate elevator maneuvers like Square Horizontal Eight Top Hat Triangular Rolling Loop Figure M thats beyond level Novice Sportsman class maneuver discussion anyway point dont set airplane up give control needed perform ma nuevers too much elevator control available loops will jumpy Smoothness part game controls set up give just whats needed maneuvers will smoother beginners think have to loop airplane pull back stick hold true resulting maneuver will look something like loop wont round problem force gravity acts direction distorts shape loop Two other factors distort shape loop variations aircraft speed wind Wind effects will covered later

elevator control variation func tion small loop much speed variation airplane experiences during loop smaller loop less speed variation smaller required elevator control changes will make round loop So Pattem fliers perform large loops Because look better small loops control input changes arent really difficult mas ter first few loops novice flier Id recommend holding constant elevator control put until confidence performing maneuver developed flier comfortable doing three loops should try varying elevator input get loops round Out What about effects wind Its obvious practice doing three beautifully con centric loops calm air try same thing headwind loops will displaced downwind overcome loop displacement elevator control should eased little sooner upward path put little sooner downward path stronger headwind sooner both should done Crosswind difficult handle fliers ways handle its effects Some fliers try hold small amount aileron during time airplane upright use part airplanes lift counter sideward mo tion due wind difficult suc cessfully partly because hard get just right amount aileron input also because loops judged well wings-level atti tude achieved during loops noticeable bank necessary counter effects cross wind judges will downgrade maneuver better way handle effects cross wind use rudder Some fliers put little rudder hold way around loop Others use rudder input airplane upright Usually very little rudder input re quired very stiff crosswinds air plane properly set up deflection rudder wont cause rolling tendencies wings will stay level So far havent mentioned using aileron control keep wings level properlytrimmed airplane wings will stay level during loops no aileron control inputs will necessary However heavy wing warp wing will cause airplane try twist away desired vertical plane loop novice fliers find difficult make aileron cor rections airplane inverted wait until bottom part loop make nec essary aileron inputs Experience

letting go elevator stick input just airplane passes through horizontal may little difficult judge first confidence maneuver developed gets easier easier takes care Inside Loops Fortunately lot what takes perform Inside Loops prop erly also works Reverse Outside Loops toughest parts Reverse Outside Loops whether youre doing three entry exit way both parts well leam proper technique practice Timing Important doesnt come easy fliers half-roll inverted flight should ini tiated early airplane should inverted second prior elevator push loop takes lot distance perform half-roll inverted flight fliers think airplane set up perform three rolls about five six seconds half-roll will consume about second means maneuver must initiated about two seconds before airplane passes front flier Since Pattem airplanes travel about 100 mph con verts about 300 feet travel during half roll inverted flight Start maneuver early Most airplanes require touch Down elevator following half-roll keep airplane level flight timing technique come Some fliers start put down just before half roll completed others walt until airplane inverted alrplane different needs different technique find out what works yours Reverse Outside Loops performed just like Inside Loops except Down elevator used insted Up elevator Rudder corrections tricky because everything seems backwards Fliers use kinds mental tricks figure out way push rudder control best Ive heard imagine youre hanging straps inside airplane what comes nat urally Dont surprised have lot trouble learning proper rudder input direction occasion some really good fliers have problems figunng out what use Aileron corrections usually fairly simple because airplane responds way expect toughest part Reverse Outside Loop exit Timing critical because just right amount Down elevator must released airplane passes through horizontal take air plane out loop level flight Most fliers either wait too long dont relese enough Down elevator airplane baboons wish dime time airplane ballooned exiting Three Outside Loops However easy wouldnt get much satisfaction learning properly After airplane has horizontal about second roll up upright flight Depending
