(which does not require periodic replacement) and not a battery, it still should have regular checkups for wear and tear. We recommend sending your system to the Futaba Service Center annually during your non-flying-season for a complete checkup and service. - Page 6 Always pay particular attention to the flying field's rules, as well as the presence and location of spectators, the wind direction, and any obstacles on the field. Be very careful flying in areas near power lines, tall buildings, or communication facilities as there may be radio interference in their vicinity. If you must fly away from a club field, be sure there are no other modelers flying within a three-to-five-mile range, or you may lose control of your aircraft or cause someone else to lose control.

No more fussing with getting trim in just the right spot for landings! Throttle cut (TH-CUT ) (ACRO/HELI): provides an easy way to stop the engine by flipping a switch (with T HROTTLE TICK at idle). -
Page 34: Dual Rates And Exponential ( D/R,Exp )
Dual/triple rates and exponential (D/R,EXP): assigns adjusted rates and exponential. Dual/Triple Rates: reduce/increase the servo travel by flipping a switch, or (ACRO) they can be engaged by any stick position. Dual rates affect the control listed, such as aileron, not just a single (ex: channel 1) servo. For example, adjusting aileron dual rate will affect both aileron servos when using FLAPERON, ELEVON, and a CCPM helicopter. - Page 35 Adjustability: • More sensitive around neutral. (positive exponential, see example) • Less sensitive around neutral. (negative exponential, see example) For ACRO throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle response, so that each 1/4 stick increases engine RPM 25% of the available range.

72. For aerobatics, gyros on rudder and elevator fix over-rotation of snaps and spins as well as tail wagging in stall turns. (Futaba offers a twin-axis gyro, GYA-352, that controls two axes with a single gyro.) For 3D aerobatics (below stall speed, such as torque rolls), heading-hold/AVCS gyros on rudder and elevator dramatically simplify these maneuvers. -
Page 57: Helicopter Functions
HELICOPTER MODEL FUNCTIONS Please note that nearly all of the BASIC menu functions are the same for airplane (ACRO setup) and helicopter (H-1/H-2/HR3/HN3/H-3/HE3) setups. The features that are identical refer back to the ACRO chapter. The Helicopter BASIC menu includes the normal conditionís throttle and collective pitch curves and revo. mixing. (idle-ups and throttle hold are advanced features and are in the ADVANCE menu). -

Page 65: Setting Up The Normal Flight Condition
Setting up the Normal Flight Condition: The Normal flight condition is typically utilized for hovering. The throttle and collective pitch curves are adjusted to provide consistent engine RPM despite the increase/decrease in collective pitch of the blades. This keeps the engine from "bogging down" under excessive load (like trying to accelerate a car on a steep hill in 5th gear) or excessive RPM under insufficient load (like flooring the throttle while in neutral), risking engine damage. -

Adjust the first point. (Ex: 5%.) to 5%. Base point: Adjust base point of throttle curve until engine idles Open the PIT-CV/NOR function. -
Page 67: Heli-Specific Advance Menu Functions
HELI-SPECIFIC ADVANCE MENU FUNCTIONS THR-HOLD: This function holds the engine in the idling position and disengages it from the T when S HROTTLE TICK WITCH E (7CH) or G (7CA) is moved. It is commonly used to practice auto-rotation. Prior to setting up THR-HOLD, hook up the throttle linkage so that the carburetor is opened fully at high throttle, then use the digital trim to adjust the engine idle position. -
Page 68: Th-Crv, Pi -Crv And Revolution Mix(Revo)
THR-CURVE and PIT-CURVE: These 5-point curves are utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Curves are separately adjustable for normal, idle-up 1 and idle-up 2. In addition, a separate collective pitch curve is available for throttle hold. Sample curves are displayed in the appropriate setup types (ex: normal flight condition, p. -
Page 69: Idle-Ups
Revo. mixing rates are linear curves. For a clockwise-turning rotor, the rudder is mixed in the clockwise direction when collective pitch is increased; for counterclockwise-turning, the opposite. Change the operating direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and vice versa. Revo. -
Page 70: Trims/Offset
OFFSET: Optional separate trims in addition to those for the normal condition. This function is used to automatically change the trim of a helicopter, for example, when transitioned from hover to flying at high speed. A clockwise-rotation rotor helicopter tends to drift to the right at high speed, so an aileron offset may be applied to offset the helicopter to the left. The necessary elevator offset varies with model geometry, so it must be determined by noting collective pitch changes at high speed. -
Page 71: Hovering Setups
HOVERING ADJUSTMENTS (HOV-THR and HOV-PIT): Hovering throttle and hovering pitch are fine-tuning adjustments for the throttle and collective pitch curves individually, fecting performance only around the center point. They allow in-flight tweaking of the curves for ideal setup. Note: HOV-THR is active in normal with and option for normal and idle up 1. HOV-PIT is only active in normal condition. -
Page 72: Gyros
As you ease off the rudder, the gain increases again, minimizing tail wag and keeping the model straight. (If your gyro does not include stick priority, you can manually create it. Please see www.futaba-rc.com\faq\faq-7c.html.) Choosing the right gyro for your skills, your helicopter, and your budget: •... - Page 73 Gain Example for AVCS/Heading-hold Gyros (GY) GOAL of EXAMPLE: STEPS: INPUTS: Open and activate the GYRO function.
