RADIO CONTROL HELICOPTERS iiTi IN THE SEPTEMBER ISSUE MA talked about using computer heli radio set up straight-line pitch curve once have determined high low pitch end points However measuring high low end points requires use pitch gauge put another way helicopter fly designed personal desires pitch gauge enables set pitch angle attack rotor blades whatever position range desire must set correctly within certain limits Although several pitch gauges market sometimes its difficult determine best recommend both easy use gives repeatable results Notice did say has accurate First have no way knowing pitch gauges accurate just take reading assume manufacturers have made gauge correctly say gauge accurate another depends largely manufacturing process cannot evaluate Plus will see later accuracy readings depends gauge also level flybar swashplate well visually align everything about later two pitch gauges easy use give repeatable results reason ably priced made Miniature Aircraft other Kalt Both slip blade easily easy align visually have large easy-to-read numbers Some others complicated require levels hold gauge position very easy use flying field overall accuracy isnt better Whatever pitch gauge use its important follow least few basic principles get accurate repeatable readings First recommend placing gauge rotor blade near root rather tip its easier line up make sure flyhar swashplate level parallel before readings taken Kalt Cyclone II helicopter shown photos notice swashplate flybar parallel level perpen dicular main shaft Once accomplished Kalt pitch gauge may adjusted top surface again parallel flybar pitch reading degrees taken directly Kalt gauge Kalt gauge also has convenient knob locks gauge particular setting linkage adjustments can made quickly set desired pitch particularly useful initial setups manufacturers recommendations whether maximum pitch minimum pitch hover pitch just check overall range pitch movement photo can also see said accuracy gauge less important its ease use repeatability results Although human eye very accurate appears photo swashplate flybar level aligned no way absolutely sure either slightly off pitch readings gauge will inaccurate means readings taken gauge probably within 10 accuracy range work thats fine Remem ber initial setup just get blades proper flying range further adjustments made once see helicopter performs advent new computer radios has made much easier make further pitch adjustments flying fieldand almost flying helicopter Its certainly uncommon make short flight land engine idle use pitch-curve function radio make slight adjustment fly again see results case pitch gauge used make adjustment once helicopter does fly perform satisfaction gauge can used record particular pitch settings helicopter can set up again after maintenance repairs etc Another use pitch gauge flying field compare two helicopters pitch flying characteristics someone has similar helicopter flying well would easy see what pitch settings adjust machine accordingly would least place start another reason whatever gauge choose should easy use flying field recently bad chance use Soundmaster Hl muffler
