Radio Control: Scale Aerobatics

RADIO CONTROL SCALE AEROBATICS -T F-1'i 4 WHEN WE LAST visited gave description chart help work four-point roll Although wrote about knife-edge flight before probably found plenty challenge perfecting four-point roll pilots uncomfortable part four-point roll upright quarter-roll inverted second knife-edge Thats because people work knife-edge flight rolling fairly quickly upright 900 position quickly quarter-rolling back upright thoughtful enough practice maneuver both directions get used adding rudder opposite direction aileron Thats okay rolling quickly adding rudder always start upright roll inverted position second knife-edge four-point roll may feel strange use rudder same direction aileron though know correct cant give hints get past parts flying cure spend time practicing maneuver getting comfortable practicing fourpoint roll dont stop until really doing maneuver properly means ensuring line rolling remains straight level maneuver properly centered Also segments should equal lengths roll rates should consistent As long youre going take time learn maneuver should learn well would probably helpful have friend watch fly give some feedback youre doing Sometimes get busy flying maneuver its hard honestly evaluate results own efforts getting complacent four-point roll upright go up safe altitude try inverted Dont discouraged have trouble new attitudemost pilots Think through reverse direction rudder inputs first quarterroll same rudder third quarter-roll opposite rudder work out Moving bit beyond four-point roll about trying eight-point roll really fun quite enjoyable watch An eight-point roll four-point roll hesitations added 450 roll Thus first portion roll 450 bank roll 900 knife-edge 1350 inverted etc hold off eight-point roll until comfortable four-point rolls Ive seen jet guys eight-point rolls ever touching rudder Too badthey miss fun Scale Aerobatic mount will allow such simplification fact eightpoint roll will require master smooth application rudder elevator can get lazy wait apply trim inputs rudder elevator 900 position four-point roll will work eight-point roll may need make inputs rudder elevator position eight-point roll except inverted portion hold duration hesitation Enter maneuver upright flight much room maneuvering area box possible dont get too rushed Roll 450 halfway knife-edge As knife-edge four-point start applying bit rudder soon start rolling opposite direction aileron input some airplanes small amount ui elevator also needed maintain heading position Hold point briefly roll another eighth 900 knife-edge position needed up elevator first point release during roll adding rudder required hold knife-edge After another pause roll 1350 positionhalfway between knife-edge inverted Release about half rudder holding knife-edge same time will likely need input small amount down elevator maintain line Roll another 450 inverted position rolling release remaining rudder adding down elevator needed maintain level flight Are getting idea fairly complicated maneuver youre pointing ground can roll out get overloaded Always roll out need abort never pull elevator preceding text talks through first half maneuver other half same except rudder elevator inputs reversed learning can certainly ignore elevator inputs except inverted keep hesitations short eighth-rolls fast elevator wont matter much rudder application will less critical Theres nothing wrong keeping simple first few sessions As get comfortable yourself favor slow down can really enjoy eightpoint roll such great maneuver impressive watch its certainly worth whatever number sessions takes master Next time Ill write briefly about slow roll basically eightpoint roll hesitations time master maneuver will definitely have developed fine degree touch sticks Meanwhile may want have little fun much simpler maneuver will serve impress spectators Having mastered simple knife-edge flight work knife-edge circle fun maneuver much harder knife-edge pass except getting used seeing model new attitude relative position Thats fairly big except though move airplane out up keep things safe inside up-elevator knifeedge circle start normal knifeedge pass As airplane center box bottom model toward pull bit up elevator airplane will turn knife-edge away Use rudder needed maintain altitude adjust diameter circle elevator Since dont 122 Model Aviation rse controls point during maneuver need give less input needed have completed circle back center stage release elevator finish knife-edge pass get comfortable inside circle knife-edge try outside circle using down elevator Just make sure roll looking top airplane before push elevator airplane again does circle starts going away flightline inside outside knife-edge circles feel good put together knife-edge 8 changing direction elevator input complete first 2700 circle after complete second circle has changing direction coming closer flightline starting position assuming circles remain round Enough about flying now Lets discuss goodies looked Hangar 9 Almost Readyto-Fly production CAP 232 local hobby shop looks excellent value anemic checkbook kept grabbing spot amusement building done looks done quite well cowl pants molded fiberglass plastic come already painted match UltraCote covering already applied Youd have some extra work make kit turn out looking good size preferred range 73-inch span 1031 square inches area made 120 150 power control surfaces beveled allow extreme throws needed radical 3-D style flying target weight 11-12 pounds will make tame enough moderately advanced sport flier handle ease makes kit very appealing choice havent mentioned part really amazes street price less $350 hope get chance fly soon flies well several reports indicate may have find way squeeze budget pick up Hangar 9 line distributed Horizon Hobby Distributors means should first check favorite hobby shop doesnt have kit call Indy R/C Horizons retail discount outlet
