Flying The Xtreme | 45> Before moving on to EXPERT MODE, fully gain confidence in sport mode first. Do notprogress too fast, be patient and disciplined before you move on to the next mode, toavoid crash and disappointment.> A brief summary of the sport mode:» Sport mode is not designed for confined indoor flying.» Sport mode is ideal for AERIAL PHOTOGRAPHY and SEMI-AUTOMATICACROBATIC fun flying.» ACRO mode is enabled in sport mode.» ALTITUDE HEIGHT HOLD FUNCTION is enabled in sport mode.» AUTO-LEVELLING is enabled in sport mode.> It is recommended to use this mode for carrying a camera and FPV equipment.18.4.4 Expert mode> The EXPERT MODE unleashes the full potential of the Xtreme, banking angles andpower output are significantly increased, acceleration sensor is deactivated, allowingfully pilot controlled flipping and rolling.> The expert mode has a similar feel as a 4-channel CCP model helicopter in headinghold mode. It is AGGRESSIVE and RESPONDS VERY DIRECTLY to the pilot’scontrol lever inputs. Best results can be achieved in PPM configuration.> This mode is designed for pilots who have fully gained experience and confidence withflying the »Xtreme. It allows fast passes, loops, rolls, flips at the pilots own ability sincecontrol functions such as AUTO-LEVELLING are completely disabled.> A brief summary of the expert mode:» Expert mode is not designed for confined indoor flying.» Expert mode is ideal for pilot controlled ACROBATIC FUN FLYING.» ACRO mode is DISABLED in expert mode.» ALTITUDE HEIGHT HOLD FUNCTION is disabled in expert mode.» AUTO-LEVELLING is disabled in expert mode.18.5 Your first flight18.5.1 General information> The »Xtreme is essentially equipped with the handling of a normal helicopter. Thedifferences, however, are in the detail. For helicopters, the torque balance is stabilisedby special gyros (in the rudder function). For this, there are two different systems:“Normal gyros” or gyros with the “heading lock” function.> Normal gyros stabilise (cushion) the tail propeller against tipping motions which arecaused by the pilots (driving speed and/or elevator changes and/or external influences(e.g. side wind). A gyro with “heading lock” function has a holding action against thesetipping motions. Both systems respond after a control command – e.g. “rudder to theleft” and subsequent neutral positioning with the immediate stopping of the tippingmotion.> In your »Xtreme, unlike in standard helicopters, there are six gyros installed for therudder, elevator and aileron functions. The installed gyros are – in comparison withstandard gyros – neither to be described as normal gyros nor with “heading lock”function.> The gyros in the »Xtreme are linked together so that after the end of a control commandthe »Xtreme always attempts to reach neutral position (hovering flight). Of course, howwell this works depends on the space available, the flight speed and/or the prevailingflight condition, the trim values of the »Xtreme and external flight conditions e.g. wind.> This control logic is deactivated in EXPERT mode. The position and flight control ofthe »Xtreme corresponds to the last control command and is not neutralised.18.5.2 Placement at start positionPlace the model on a level surface as smooth as possible (e.g. stone floor). A carpet is lesssuitable because the landing legs may get caught in the carpet easily.
