User manual FUTABA 8UHPS

[. . . ] Thank you for purchasing a Futaba® 8Usuper series digital proportional R/C system. This system is extremely versatile and may be used by beginners and pros alike. In order for you to make the best use of your system and to fly safely, please read this manual carefully. If you have any difficulties while using your system, please consult the manual, your hobby dealer, or Futaba. This manual is not just a translation and has been carefully written to be as helpful to you, the new owner, as possible. [. . . ] For your convenience, the normal curve can be programmed in either the Basic or Advance Menu, and it is automatically updated in both places. Switch G is programmed so that you may change between the normal (NORM), idle-up 1 (IDL1), and idle-up 2 (IDL2) curves. The normal throttle curve (TH-CRV NORM) function is used to produce the basic throttle curve for flight near hover. It is used along with the normal pitch curve (PICRV NORM) so that the helicopter flies with constant rotor RPM. The normal throttle curve function is ON at startup. The idle-up curves should be programmed so that the engine maintains constant RPM even when the pitch is reduced during flight. The curves should be matched to loops, rolls, and other maneuvers, and are divided into idle-up curve 1 and idle-up curve 2. The TH-CURV functions for IDL1 and IDL2 curves will not operate until the OFST-1 and OFST-2 functions are activated.

The blinking item on the Top arrow indicates the current stick setting screen is the position (2 arrows means it's between current setting item. points) Curve points 1-5 The bottom arrow shows the point on the five-point curve currently being set. Input 5-point curve values Move the lower arrow to the position you want to set with the CURSOR keys (the curve point is indicated by the arrow below the Curve Point Value numbers 1-5, and the current (Range: 0 - +100%) throttle position is above the Initial curve settings: numbers). POS2 = 25% · If you're unhappy with what you've POS3 = 50% set, you may return to the default POS4 = 75% value by pressing the (+) and (-) POS5 = 100% keys simultaneously. These keys are used to move through the To TH-CRV five submenus in the IDL1 function TH-CRV function. Curve Name Display (NORM) To PI-CRV NORM function Data input keys To TH-CRV IDL2 function Idle-up 1 Curve Setting The TH-CRV IDL1 function will not operate until the OFST1 function is activated. The curve setting procedure is the same as normal curve described above. To TH-CRV function Idle-up 2 Curve Setting The TH-CRV IDL2 function will not operate until the OFST2 function is activated. The curve setting procedure is the same as normal curve described above. To TH-HLD function CAUTION Before actually starting the engine, be sure that idle-up switches 1 and 2 are off, and the throttle is set near engine idle. To TH-CRV IDL1 function 48 The Throttle Hold function holds the engine throttle in the idling position and disengages it from the throttle stick, whenever switch E is activated. You can set the throttle position to be held over a -50 to +50% range centered about the throttle idle position. Rudder offset at throttle hold The rudder offset function contained in throttle hold is used to offset the tail rotor pitch neutral position during autorotation. It is set to keep the fuselage from rotating only when the throttle hold function is active. You may also input a time delay for the offset to be implemented (to prevent sudden trim changes) in the DELAY menu within Advance menu. Turn the TH-HLD function ON by pressing the (+) key ("ON" or "OFF" displayed depending on SW-E position). Hold position Range: -50% to +50% (Initial setting = 0%) These keys are used to move through the four submenus in the TH-HLD function. Rudder offset function First activate by pressing the (+) key ("ON" or "OFF" displayed). [. . . ] Flap offset* To START function Data input keys Input the desired Flap offset Channel with the (+)/(-) keys. Aileron 2 offset for START Input the desired Aileron 2 offset with the (+)/(-) keys. Servo offset Range: -100 to +100% (You may reset to zero by Initially set to 0% *The GLID 2FLP menu for SPEED has pressing the (+)/(-) keys separate Flap 1 and Flap 2 offsets. simultaneously. ) -9090 The setting data for 8 models can be saved in the T8UHPS transmitter itself and the setting data for 8 more models can be saved in the DP-16K CAMPac (Option) removable memory module.
