Swash Right Servo to be tremendously strong. The Tiger 50 has been extensively flown with standard 40-oz ball bearing servos - with excellent results. However, extreme performance pilots will notice a nice improvement when upgrading to digital servos.

6.4 AVIONICS ISOLATION CAUTION The importance of protecting the avionics package (receiver, gyro amplifier, governor, and battery pack) from the primary vibrations caused by the engine and the secondary vibrations induced by the main and tail rotors cannot be overemphasized. These forces may lead to premature failure of the avionics components leading to intermittent or permanent loss of control * PRO TIP: The gyroscope platform should...

9.0 SET-UP TIPS For the Tiger 50, the steps are first a symmetrical This segment of the manual deals with setting mechanical set-up followed by any adjustments up your helicopter in preparation for flight. The set-up includes both mechanical and electronic for the lighter duty needs of the upright regimen (accomplished in the radio).
Page 31
However, servo failure is more likely than mechanical failure. Thus, inherent in the design Perpendicular to of the Tiger 50 is the elegantly very simple to the tail boom understand concept of reducing the number of parts in the model to increase reliability (fewer things which can possibly fail).
Page 32
SET-UP TIPS - CONT. Verify pushrod lengths for the three CCPM servos. Also verify the HD-mark on each of the plastic ball links face the screw-head side of the ball. (Figure 4) Figure 4 * NOTE: Ensure the pushrods (linkages) for the fore/aft servo, both side-to-side cyclic servos, as well as the T/R (tailrotor) T/R Servo...
Page 33
SET-UP TIPS - CONT. TAIL ROTOR - MECHANICAL SET-UP: Mechanically setting up the tail rotor (T/R) is next. The pushrod length shown for the neutral position is for hovering. Again, this is the point at which both tail rotor control arm and tail rotor servo arm make a 90 to the tail boom.

SET-UP TIPS - CONT. ELECTRONIC SET-UP: Pitch Curves So what does a pitch curve look like? This is what We suspect that in the course of learning about a collective pitch might look like. (Figure 8) model helicopters you’ve heard the term pitch Figure 8 Pitch Curve curve or throttle curve bandied about.
Page 36
Oh, and in case you’re wondering, no we’re not going to teach you how to program a specific radio to the Tiger 50 in this manual. There are too many radio systems with excellent manuals which explain exactly how to set-up a CCPM heli for us to replicate all their work.

flight management and will permit the easiest make adjustments. It’s quite easy and takes only way to master aerobatic flight with the Tiger 50. a few minutes to program into the transmitter! (Figure 11)

SET-UP TIPS - CONT. ELECTRONIC SET-UP: Throttle Curves You may have noticed the T/C stick is no longer As with pitch curves, throttle curves are just the symmetrical for the Normal Curve in an upright oriented system because there’s 11 of pitch be- graphical representation of servo position as it relates to stick position.
Page 39
SET-UP TIPS - CONT. What’s immediately apparent is the throttle closes Throttle Curves: Idle Up and Hold Conditions until it hits 0 pitch at which point as the pitch goes While the throttle and the collective pitch servos negative, the throttle opens up again (some) in an move at the same time, or are linked, for Normal effort to keep the main rotor blade speed constant.

10.0 SET-UP TIPS - CONT. upright oriented helicopter will look more like The amount of throttle in the Hold curve is also determined by experiment. Usually the idle this. (Figure 18) setting is a little bit higher than normal, not a Figure 18 Normal Throttle Curve - sport lot, just enough to ensure the engine will not...

10.1 SET-UP TIPS - CONT. of pitch and then the curve climbs as the throttle establishing the neutral point for all the linkages is opened to account for the fact the main rotor (and ensuring the control and servo arms make blade system is being loaded again as pitch perfect 90 angles as they meet) is the desired...
Page 42
10.2 SET-UP TIPS - CONT. FIELD SET-UP: Blade Tracking You’ve completed an initial set-up on the workbench; now it’s time to make some fine adjustments. The first thing to do is remove the canopy because this will permit easy access to the linkages. This will have a negligible effect on trimming the model, but the prudent modeler may add about 6 oz.
10.3 ADDENDUM www.audacitymodels.com A goodie bag of parts, plus some tips to make the Tiger better, are what this addendum is all about. ADDENDUM v1.9 Parts included: 10) AUD1012 Servo Bosses, 1) AUD0548 Seesaw, and 2) AUD3505 Buttonhead Bolts 1. The new servo bosses AUD1012 5.
www.audacitymodels.com 10.4 ADDENDUM 10. There’s a mistake in the manual affecting steps 3.3 and 7. Servo arms are an important part of setting up your 3.5 because these bolts are reversed. The correct bolts to Tiger. There’s a mistake in the manual on pages 26, 27, mount the engine to the engine mount (as detailed in step 3.3) and 31 where we suggest using 20 mm long servo arms for the three swashplate servos.
