Futaba 9CHP Super Typical Switch Assignments

2006 Apr 2

From the photo, all switches for normal and initial start ups begin with the switches toggled back towards the antenna. With the switches in this initial start up position, one can tell if any of the switches are in the abnormal position from a visual perspective.

With the exception of the throttle hold switch "G", any switch that will be assigned to a throttle function, will be assigned to the switches on the left side of the radio. Hence, the left hand controls the throttle stick function.

The throttle kill switch is assigned to switch "A" as oppose to the trainer switch "H". I have found this to be more convenient and primarily due to the left hand controlling any throttle function. Some like the momentary function of switch H as their preference for the throttle kill function. Another reason that I have selected switch "A" is to avoid the constant reprograming especially if you buddy box frequently.

For the GV-1 and Throttle Jockey governor, I have selected the "E" and "F" switches. Primarily because my left hand controls the throttle function. Due of the inherent design of the Throttle Jockey, I have selected the idle up switch "E", normal mode to turn off the Throttle Jockey.

There was an instance where I had the Throttle Jockey setup per the instructions for switch "C" and with the center position of the switch set for governor off. A lesson learned was that the governor was always in the on position at 1750 rpm, switch "C" toggle back. I flipped the heli inverted in normal mode, being on the assumption that I was on idle up due to the high rpm sound of the engine. Well, you know the rest of the story ... Just be careful when having a setup that their are no noticable differences in rpm between normal and idle up modes.

Switch "D" will be assigned for dual rate for the rudder only. The purpose for this is to control (slow) the piro rate when practicing any piro maneuvers. Dual rate for the aileron or elevator will not be necessary since the exponential function will slow the rate of travel around center yet providing full travel towards the extreme.

All the variable knobs / sliders controls should be INHibit. Please check and ensure that the throttle and collective servos do NOT function when these knobs are moved. To verify this, place the throttle / collective stick to the half stick position and move the variable controls.

The Futaba 9CHP Super radio, has what is called a High / Low Pitch curve menu that must be set to MAN function in order to inhibit it's assigned knob / slider control from affecting your high and low pitch curve settings. This function, if active will also give you a non linear pitch curve if active. To verify this, go to your pitch curve menu screen and look at the graph. The graph should be linear from 0% to 100% while moving the knob / slider controls.

So there you have the basic layout of my switches and their configuration.
