User manual SANWA RDS8000FHSS

[. . . ] In designing the RDS8000FHSS we have made every effort to provide you with a radio that will allow you to extract the maximum performance from your powered aircraft, sailplane, or helicopter, while at the same time simplifying the task of setting up and adjusting your model. These instructions are written in great detail to help you understand what all of your RDS8000FHSS capabilities are. Because of the many features of the RDS8000FHSS, this manual is quite long. To actually use the system, you may only need to read the INTRODUCTION section, the Common Functions section, and study the section that applies to your type of aircraft. [. . . ] However in some cases it is not possible to use full servo movement such as those instances where short control horns must be used because of aircraft design considerations, or with fixed length control horns such as a throttle arm. To electronically do so, we first bring up the STW (stopwatch) screen as previously instructed in INITIAL SETUP. Next press the FUNCTION down key until the EPA screen appears for the Elevator channel. The EPA of the Elevator channel can be adjusted from 0% to 150%. By moving the elevator stick up and down, you will see the LCD arrow change according to the direction you are moving the stick. To set the UP EPA, move the stick back past the neutral position and release the stick. You can increase or decrease the amount by using the (INC+) or (DEC-) function keys. Note that you can move across the menu using the (CH+) or (CH-) keys to adjust EPA for all other channels. To adjust the EPA on Gear and Flap channels simply move the toggle switch up or down and adjust the EPA accordingly. 36 G (Landing Gear End Points) In most cases, (almost all cases in the past) the total servo throw for the landing gear function could not be set by the transmitter, because most retract servos are SWITCHED (non-proportional) servos. With these servos, mechanical adjustment was the only method available to ensure proper operation of the retracts. Airtronics now offers a high Torque PROPORTIONAL retract servo, p/n 94739. With this servo and the RDS8000FHSS transmitters, End Point Adjustments for the retract servo are possible, independently setting the "Down" and "UP" lock positions in mechanical retracts, and precise adjustment of the air valve in pneumatic retracts. To use this function, select the EPA function as shown on the previous screen. Press either the INC +/YES or the DEC -/NO key to change the value and / or polarity of the function. The FLAP/FL-EL switch located on the top-right of the transmitter activates the Flaperons. Note that if the ailerons go up when the Flap switch is activated, change the polarity of the programmed value. Use the FLAP TRM (trim) function to fine tune flap operation. 40 ALARMS D/R-A(DUAL RATE ALARM) THROTTLE STICK HIGH The RDS8000FHSS offers an "ALARM" function to warn you if you turn your transmitter on while a Dual Rate Switch is activated, and another to warn you if you turn the transmitter on while the Throttle Stick is in any position other than FullLow throttle. Will be displayed on the LCD screen until you place the Throttle stick in the full-low position. To activate the D/R-A (Dual Rate alarm), press the (CH ­) or the (CH +) key to select "etc" on the Channel indicator. Press the FUNCTION down key several times to scroll down the menu items and select the D/R-A screen. Next, press either the INC +/YES or the DEC -/NO key to set D/R-A to ACTive. If a Dual Rate switch is in the ON position when you turn ON the transmitter, an audio tone signal of 3 beeps will occur approximately every 15 seconds until you turn off a dual rate switch. If you wish, you can turn off the Dual Rate alarm by pressing either the INC +/YES or the DEC -/NO key to change D/RA to INHibit. NOTE: The RDS8000FHSS transmitter will also sound an alarm if the power switch is left on with out any movment of the controls for a period of time that exceeds 15 minutes. The screen will show PWR!. 41 DELTA (ELEVONS) DELTA mix can be used in a flying wing type model to provide ELEVON control, where the elevator and aileron functions are combined. To access the DELTA function, use either the (CH ­) or the (CH +) key to select the STW screen. Press the FUNCTION down key to scroll down to the DELTA screen. Now press the INC + /YES key to change the display to ACT(Active). Note that you cannot have FLAPE (Flaperon) Active when DELTA is Active and vice versa. [. . . ] To activate Dynamic Trim Memory, press the (CH +) or the (CH ­) key to select "etc" on the Channel indicator. Now, press the FUNCTION down key to scroll down the menu to the DTM screen. Press the INC +/YES or the DEC -/NO key to change DTM to ACT (active). Press the END key to return to the STW screen. Once activated, the Dynamic Trim Memory function is transparent to the pilot. Simply activate a Flight Mode, (for instance "Normal") and trim the aircraft for stable hover using the digital trim keys. Note that when you change flight modes, the servos affected by the DTM function will return to the original neutral position regardless of the value of trim set-in for the previous flight mode.
