RADIO CONTROL HELICOPTERS F11 E THE ADDRESS top column means have finally moved Living twobedroom apartment past eight months house under construction nicer thought would life simple barest necessities Now have household goods storage will still several weeks until have garage workshop set up way want However admit am having fun process getting rid small outdated parts havent used years saved thinking would come handy someday someday out go wonder discarded pieces Ill need next project Jett Engineerings Sport Jett 40 engine has installed Ergo 30/40 able try couple test flights wrote about experiment several months ago because technical problems associated mounting engine tools storage move cold snowy winter weather Pittsburgh first opportunity get model air talked Dub Jett about manufacturing engines specifically helicopter fliers said familiar helicopter engine requirements Thats came up idea see stock 40-size engines would work Ergo Dub idea slightly modify carburetor helicopter use change stock configuration carburetor settings off initial engine start turned out very rich high side lean idle side engine started almost immediately settled down good idle obvious added power engine very rich appreciated SuperTigre type needle valve Dub uses noncritical its setting threads needle valve fine allowing -turn have serious effect engine performance like much better one- two-click change other carburetors also became obvious Sport Jett 40 has substantial power didnt lean out way what would need 3-D flying still pulled Ergo straight up like rocket little refinement high-end mixture change pitch curve handle added power think will real mover also impressed transition idle full power well transition back steady dependable idle right out box testing flying needs done before Dub have confidence overall performance engine helicopter use Jett Engineerings high quality performance evident received letter Chris Jerome Lewisville NC think will interest ready progress forward flight help book Basics Radio Control Helicopters Second Edition Chris teaching himself fly ready forward flight after reading March column appreciate Chriss letter because gives better perspective what its like learn forward flightit has years since position have helped fliers progress since Chriss comments well-taken could present different opinion techniques Ive included summary few comments own 1 agree flight simulator does help learning process Its really anything like knee-knocking experience real thing does help practice stick movements need make Chris said couple flight simulators real benefits gives stick time progress provides threatfree environment afraid make mistake crash helicopter Taking away fear factor big plus 2 experience has windless day much better 5-10 mph wind recommend column book Chris said may because very rarely have steady wind around nearly always gusts little changes direction found very hard get out forward flight hover close-by low Therefore would recommend getting used hovering landing helicopter 10-15 feet some distance before go forward flight agreeif choice between gusty day calm day Id prefer calm However recommend 5-10 mph wind steady wind because does good things helicopter practicing forward flight First keeps helicopter translational lift hovering good because engine rotor system working hard would hovering calm day Second steady wind slows down ground speed helicopter flying wind gives little time relax upwind portion pattern provides big dividends during landing approach As helicopter descends final headwind slows up entire approach giving time make corrections reducing possibility helicopter will go sailing try stop its forward flight Maybe Chris could find steady wind day would help him recover helicopter little closer 3 Chriss last point too long quote started forward flight flying figure 8s front him As improved control helicopter let 8s get progressively bigger Soon forward flight side other found biggest problems 106 Model Aviation Superio Helicopter promises zero compromises design construction See text details new 60-size aircraft keeping speed under control getting helicopter down forward speed helicopter determined amount collective lift fore/aft cyclic Having too much lift rotor system will cause helicopter climb go fast some combination two Therefore try controlling models speed keeping attitude flat cyclic controlling altitude collective certainly interaction between two way will give control movement make specific adjustment helicopter forward flight its extra translational lift could hard get down dont have enough negative collective pitchI recommend limiting amount about 1O learning hover keep helicopter falling out sky about 3O needed get helicopter down forward flight Dont forget make needed change pitch curve practice hovering new setting until feels comfortable before get helicopter away ____________________________________________ ground last point Chris makes need control tail tail rotor especially important have fixed-wing pilots rarely use rudder except steer aircraft ground tail rotor often used helicopter especially slow close ground keep nose pointing desired direction forward flight vertical fin acts like feathers arrow keeping pointy end going first hover especially calm days Chris likes vertical fin has no control function Its nice learn what other helicopter fliers agree disagree about learn about different techniques Thats what makes hobby much fun Certain
