30.6.2 Principle explained
Intraditionalying,knowingtherelativepositionofthehelicoptertothepilot(transmitter)
is crucial as stick input (except for throttle) directly affects the course. That is, if the
helicopter’snosefacesthepilotandtheyapplyaileron,elevator,orrudder,behaviouris
essentiallyreversed.Incaseoflossoforientationthepilot mayinadvertentlycrash the
helicopter.
Whenactive,I.R.P.Csolvesthisproblembyregisteringthe»NovaX350’stake-offposition
onmotorstart.Allstickinputistranslatedrelativelytothetake-offposition,regardlessofthe
»NovaX350’spositioninight.Inotherwords,ifthepilottakesoffwiththe»NovaX350’s
nosefacingawayfromthem,stickinputalwayswillaffectthecourserelativetothetake-off
position. [ Fig. 18 ] illustrates this priciple based on a mode 2 transmitter.
Mode 2
A - Take-off position B - I.R.P.C. On
Mode 2
Fig. 18
[ Fig. 18 ]:
[A] denotes the take-off position and [B] the behaviour when I.R.P.C. is on. In [B] the
»NovaX350 hasbeenturned by180°and movestothe rightwhen aileron isapplied,
whereasintraditionalyingitwouldmovetotheleft.Thisisbecauseallinputistranslated
relativelytothetake-offposition( [A] ).
