10. Throttle Curve WOT K lt E c 2 Wn Q 2 J un Idle Stick Position Low High The whole idea of throttle curves is for the throt tle to add or subtract power to the main rotor system by opening or closing the throttle so as to maintain the RPMs of the main rotor constant Seems simple enough as increasing main blade pitch means you increase the load which would slow down the main rotor blades unless we also increased the throttle Similarly reducing the load on the main rotor system by reducing the pitch would lessen the load on the engine which is compensated for by closing the throttle the appropriate amount understand Hence the reason why we refer to the throttle collective stick as the T C stick is because the throttle and the collective pitch move at the same time or are linked Usually Usually Yes the usual relationship means high pitch and high throttle while low pitch is linked to low throttle But there are times when this isn t the case during Idle Up and Hold 9 9 SET UP TIPS CONT Throttle Curves Idle Up and Hold Conditions While the throttle and the collective pitch servos move at the same time or are linked for Normal pitch curves as soon as a helicopter is inverted the pitch servo moves in the opposite negative direction If the system closed the throttle it would mean disaster as the rotor speed would decay Similarly to practice autorotation the pilots wishes

As you may suspect this section was created for folks to whom this is all new Experienced pilots will just glance at the pitch values we suggest and be on their way without a further glance at this manual Since we ve discussed the switchless inverted pitch curve Idle Up 1 set up let s discuss the Nor mal Pitch Curve for the same set up The Normal Pitch Curve is the one used to start the chopper carry it to the flight line and take off as well as for recovery of the model at the end of a flight Flying around is done in Idle Up 1 understand The goal is for this curve to exactly match the Idle Up 1 curve from mid stick on up because you don t want the heli to jump up or down when you engage the switch due to a difference in pitch curve profiles Thus the top end pitch will be the same the hover pitch will also be the same and will still occur at 3 4 stick exactly as it does for idle Up 1 Similarly mid stick will continue to be 0 of pitch The differences in the pitch curve will only be apparent in the run up to hover The end result will be a smooth transi tion between the Normal Mode and the Idle Up 1 flight mode which can be accomplished from hover pitch on up At the bottom of the pitch range there will be about 4 of pitch to enable easy landings even in a stiff breeze Figure 10 Figure 10 Normal amp Hold switchless inverted 11 o 5 5 0 Pitch B AN Stick Position 1 4 1 2 Q A

25. how do you decide what the top end pitch will be This is determined by the power of the engine Some engines being stronger than others can pull 11 of pitch with no problem others can only pull without sagging 10 5 of pitch etc It depends on the engine However while we can directly measure the pitch of the main rotor we don t have an easy way to measure power output The easy answer to this is max pitch corresponds to max throttle opening Usually The top level aerobatic pilots however keep a little in reserve at top end pitch so they can add more power to make up for the cyclic demands of pitch and power during maneuvers but that s beyond the scope of this manual We ll get into all this a bit later when we discuss Throttle Curves We ve pretty well covered the pitch curves for an experienced pilot who wants to perform any 3D maneuvers within their repertoire Upright Orientation Normal Pitch Curve Next we ll discuss the minor changes made to the pitch curves for the pilot who is not really interested in extreme aerobatic flight First up is the Normal Pitch Curve for upright oriented flight As you ll see the curve really doesn t look very different at all but the values are quite a bit different as the hover point now occurs at mid stick In fact this is a much better set up for hovering as the sensitivity of the T C stick is reduced by half Top end pitch is not changed either Bottom end pitch is changed to the
