generally has three four things have pushed pulled rotated may saying So whats big problem Well theres big problem newcomers things pushed pulled rotated often becomes almost afterthought scheme things shouldnt Since aircraft least landing takeoff should made certain landing wheelsnot vertical inverted otherwise strange Things swing items such elevator ailerons rudder throttle arm swing must hinged pushed pulled something moves freely host hinges market ranging simple rectangular pieces material look like cloth nylon through actual metal-pinned flat nylon hinges round peglike devices metal pins strips material run entire length movable surface average trainer-type model simplest hinge install sufficient people consider simplest rectangular material pieces generally thinner tolerant sloppy installation others Newer materials type can slid narrow slot cut surface hinged seated firmly attached application thin cyanoacrylate CyA adhesive will wick back hinge surface tends create slightly stiffer hinging action isnt bad really loose hinged joint can contribute control surface flutter other things correct Make sure hinged joint doesnt stall out put too much load servo Some other types hinges such metal-pinned ones whether flat pegshaped can create neater finish job movable surface can detached purpose reattached later Just make certain pin cannot slide out both ends hinge securely attached Nothing discouraging watching elevator flutter gracefully ground model crashes important keep hinges line across surface Misalignment can cause flopping motion binding putting strain pushrods may cause sudden erratic movement surface Misalignment noticeable along greater length crops up often strip-type ailerons important lowerperformance aircraft such trainers gap between movable surface fixed portion should minimal helps enhance overall control requiring excessive surface movement accomplish gap-free joint consider shape joined surface both can rounded hinge located center arc commonly used method leave non-movable surface flat square sand V-shaped edge movable portion center hinge apex V can best accomplished using sanding block exercising care also helps find center surface correct hinge alignment have hinged joint moves freely binding tug movable surface ensure hinges arefirmly seated surfaces Dont too gentle laws science wont using wide flat hinge material could pin hinges place drilling hole through surface hinge gluing pieces round toothpicks snipped off sanded smooth Now surface moves going push move pushrod dont know called pushrods actually push pull Maybe thats akin reason have scissors instead scissor CL model pushrod runs bellcrank securely anchored pivot near center gravity CG bellcrank translates movement 46 Model Aviation
