pinching full throttle will cause speedup about 1 secondthen starts die 325X-H very out adjustment perhaps root of power problems Although am fan using test stand set mixtures engine replied could least get engine ballpark using pinch test prop idea would run engine full speed carefully pinch fuel line listen what happens engine Ideally should like just slightly rich side max power output engine should rise rpm just slightly before starting die Stephens rise rpm about 3/4 second sounds about right However problem such pinch test test stand engine probably isnt loaded will helicopter

dont think would safe message really got attention am including full story hereso everyone can benefit experience replied right away following since think must have misunderstood original reply am favor pinch test using prop test stand Please never try attach helicopter anything adjust engine other parts helicopter very dangerous horror stories about people getting severely hurt instant doing what thought completely safe ever read book basics Radio Control helicopters will remember recommend standing minimum 15 feet helicopter hovering would recommend getting closer unless blades have stopped turning someone has firm grip rotorhead should engine accidentally speed up some reason person know 30-size helicopter running ground wanted check rotor blade tracking very large powerful helicopter grabbed tail rotor gearbox tilted helicopter up front skids added power bring blades up speed still does know what happened next somehow main rotor blades hit hand breaking small bones needed coordinate movement hand fingers years several surgeries after accident hand has still healed properly has partial use hand example can become complacent dangers helicopters possess routine basis see people standing within five feet hovering helicopters giving no time escape should malfunction occur have seen expert fliers touch helicopter hovering others hovering over bystanders take photos etc Im certainly glad opportunity converse Stephen subject feel strongly about just bring up again everyones benefit know have talking lot about safety lately way can really enjoy hobby everything can keep ourselves others getting hurt Although have strong opinions subject Im too old remember back 20-plus years ago got started helicopters Air Force stationed Germany son wanted try

tether card table keep under control tried make adjustments garage Since winter snowing outside closed garage door soon filled exhaust smoke No problemI just went house got couple gas masks gave another try wasnt long before smoke thick couldnt see helicopter opened garage door neighbors thought house fire smoke sure seems funny now think back it seemed perfectly normal time what can happen get too impatient happens us Helicopter Simulator just got another nice E-mail Heather Rose Marketing Publicity Coordinator Great Planes Model Distributors describing some latest features new RealFlight Deluxe RIC Flight Simulator Although have chance see use simulator would like column future because appears have some unique features make flying fun productive Made used Pentium 200 better using Windows 95/98 simulator available its own controller can use own transmitter would certainly prefer use own transmitter possible since would get used sticks trims switches etc However can imagine someone just getting helicopters might like make initial investment using transmitter give helicopters try computer before buying real thing have original RealFlight simulator CD available upgrade latest version includes some awesome graphics allow actually see servos inside helicopter watch rotor blades come up speed blur advance throttle helicopter will emit smoke just like real machines naturally will work just about transmitter out providing large range adjustments helicopter will fly just way want info please contact local dealer visit RealFlight Web site wwwrealflightcom Tail Rotor Comp new fliers club field having problem new helicopter No matter what did just couldnt get hover correctly some other fliers gave try same problem took next logical step went through instruction manual again make sure assembled everything correctly still could find problem brought helicopter over take look knew problem couldnt very serious because very popular 30-size helicopter has reputation being great flier So suggested rather looking nut bolt step back take look big picture something looks right probably just have look something doesnt look right started looking swashplate rotor blades moving cyclic collective functions watched correct movement Everything looked fine rotor head tail rotor next moving stick side side gave proper change tail rotor blades However changed collective pitch tail rotor blades changed wrong direction means first tail rotor comp adjusted backward may familiar tail rotor comp function radios automatically changes pitch tail rotor blades collective changed get better understanding imagine helicopter hover add collective climb increases torque main rotor system would cause helicopter yaw unless correction made tail rotor could certainly make correction ourselves radio manufacturers have provided us nice feature take care automatically adjusting tail rotor comp increases tail rotor pitch slightly helicopter climbs reduces pitch slightly descends nose helicopter will stay straight ahead can imagine what would happen adjustments reversed Now nose would really swing way climbing other way descending So solution especially novice will hovering climbing descending turn off tail rotor comp altogether completely cured problem explained make adjustments should decide use feature future So helicopter flying way
