– 1 – Hitec ® ECLIPSE 7 Owner’s Manual SYSTEM INSTRUCTION MANUAL FOR AIRCRAFT • GLIDERS • HELICOPTERS 7 CHANNELS • 7 MEMORIES • PROGRAMMABLE FM SHIFT Introduction to the Eclipse 7 System Congratulations! You now own a Hitec ® Eclipse 7 , an extremely versatile R/C system that may be effectively used by both beginning and master pilots. The transmitter may be programmed for airplanes, gliders, or helicopters, all with special mixing functions, so it can accommodate virtually any model configuration. You can store programming for seven different models in this powerful system! The transmitter will remember all of your settings for each of your different models forever — no backup battery is ever needed. With programmable shift, it can be used with all PPM/FM receiver models, even other brands! The system pushbuttons allow rapid data input into the easy-to-read LCD display. With its electronic digital trims, you’ll never lose your trim positions again, because they stay at the same place you left them! Standard programming features include servo reversing for all channels, end point adjust on all channels, dual rates, and exponential. Pre-programmed functions and programmable mixers allow you to use the system for any type of model you can imagine. For those learning to fly, the transmitter has “buddy-box” capability (a second transmitter may be connected for training by an instructor pilot with an optional trainer cord). The Eclipse 7 menus even have the advanced “flight condition” settings found in other radios costing hundreds of dollars more in all its menus!! The extensive preprogrammed mixing features for aircraft include flaperon (dual aileron servos), V-tail, elevon (for flying-wing models), landing settings, throttle cut, aileron →rudder mixing, and elevator → flap. Five programmable mixers for custom functions are also provided. For sailplanes, you find the following custom programming for competition and sport models with two or four wing servos: crow mixing for spot landings, flap → aileron mixing, aileron → flap, elevator → flap, aileron → rudder, flap → elevator, two sets of switchable offsets for launching and speed, V- tail, aileron differential, and five programmable mixers. The second aileron is on channel 5, so you can use the system with ultralight five-channel receivers without any problems! Helicopter features include five-point pitch and throttle curves, high and low revolution mixing, throttle cut, throttle hold, gyro settings, and rudder → throttle mixing. You may select a conventional swashplate, or if you have a more complex chopper, mixing is provided for two types of three-servo swashplates. About this manual This manual is not just a translation — it has been carefully written from scratch to be – 3 – as helpful to you, the new owner, as possible. There are many pages of setup procedures, examples, explanations, and trimming instructions. In order for you to make the best use of your system and to fly safely, please read this manual carefully. If you don’t have time to read it thoroughly, at least spend some time browsing through it to see all the features this fine system has to offer. Eclipse 7 System Options: 1.

Tuning procedure 1. Attach 12.0 Vdc power supply 2. Using a Spectrum analyzer and a short-range pick-up antenna, look for 72MHz signal with sufficient scan width to see 30-150 MHz spurious. 3. Adjust T1, T2, T3, T4, and T5 for maximum output at operating frequency and minimum output at any harmonics. 4. Repeat step 6. 5. Check for minimum emissions from 30 to 760 MHz.

ENGINEERING STATEMENT For Type Certification of Hitec RCD, Inc. Model: Eclipse FCC ID: IFHHPF-M72 I am an Electronics Engineer, a principal the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Hitec RCD, Inc., to make type certification measurements on the Eclipse transmitter. These tests were made by me or under my supervision in our Springfield laboratory. Test data and other documentation required by the FCC for type certification are included in this report. It is submitted that the above mentioned transmitter meets FCC requirements and type certification is requested. ______________________________ Rowland S. Johnson Dated: March 6, 2001 A. INTRODUCTION The following data are submitted in connection with this request for type certification of the Eclipse transmitter in accordance with Part 2, Subpart J of the FCC Rules. The Eclipse is a low power, non-voice, transmitter intended for remote control of model aircraft in the 72 MHz band. The equipment employs a vertical polarized antenna directly mounted on the unit and meets Paragraphs 95.645, 95.647, 95.649, and the technical requirements established in the Report & Order in PR Docket 90-222. B. GENERAL INFORMATION REQUIRED FOR TYPE CERTIFICATION (Paragraph 2.983 of the Rules) 1. Name of applicant: Hitec RCD, Inc. 2. Identification of equipment: IFHHPF-M72 a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as separate exhibits. 3. Quantity production is planned. 4. Technical description: a. 6k00F1D emission b. Frequency range: 72.010 – 72.090 MHz. c. Operating power of transmitter is fixed at the factory at 0.170 Watt – ERP(d). d. Maximum power permitted under Paragraph 95.635(b) of the FCC Rules is 750 milliwatts, and the Eclipse fully complied with those power limitations. e. The dc voltage and dc currents at final amplifier: Collector voltage: 11.6 Vdc Collector current: 101 mA f. Function of each active semiconductor device: See Appendix 1. g. Complete schematic diagram is submitted as a separate exhibit. h. Draft instruction book is submitted as a separate exhibit. 2 B. GENERAL INFORMATION (continued) i. The transmitter tune-up procedure is submitted as a separate exhibit. j. A description of circuits for stabilizing frequency is included in Appendix 2. k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 3. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. 6. RF_Power_Output (Paragraph 2.985(a) of the Rules) Since the Eclipse has an immediately attached, integral antenna, no antenna port exists. Power was determined by substitution comparison. Assuming an ideal dipole (not the actual monopole) ERP(d) = 0.17 Watts. 3 C. MODULATION CHARACTERISTICS Occupied_Bandwidth (Paragraphs 2.989(i), and 95.635(b) of the Rules) Figure 1 is a plot of the sideband envelope of the transmitter taken with an Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.989(i) and consisted of the multiple pulses and synchronizing space normally used in radio control applications. Operator controls were adjusted for worst-case emission. The plot is within the limits imposed by paragraph 95.635(c). The horizontal scale (frequency) is 10 kHz per division and the vertical scale (Amplitude) is a logarithmic presentation equal to 10 dB per division. Resolution bandwidth was 1 kHz; video bandwidth was 100 kHz. Figure 2 is a plot from a Tektronix 494P spectrum analyzer with 2 mS/division sweep in the time domain of the modulated carrier. Modulation consisted of eight bursts with a nominal 0.8 mS duration at a nominal 50 Hz repetition rate. 4 FIGURE 1 OCCUPIED BANDWIDTH 95.635: (3) At least 25 dB on any frequency removed from the center of the authorized bandwidth by more than 50% up to and including 100% of the authorized bandwidth (4 to 8 kHz). (10) At least 45 dB on any frequency removed from the center of the authorized bandwidth by more than 100% up to and including 125% of the authorized bandwidth. (8 to 10 kHz) (11) At least 55 dB on any frequency removed from the center of the authorized bandwidth by more than 125% up to and including 250% of the authorized bandwidth. (10 to 20 kHz) (12) At least 56+10 log 10 (TP) dB on any frequency removed from the center of the authorized bandwidth by more than 250%.

SPURIOUS EMISSIONS AT THE ANTENNA TERMINALS (Paragraph 2.991 of the Rules) Since the Eclipse transmitter meets FCC Rules 95.645, there are no provisions for antenna terminal output measurements. Substitution of a suitable matching network and retuning to permit observations at 50 ohms would not be representative of normal operation. Accordingly data on radiated spurious emissions are included in lieu of antenna terminal conducted spurious emissions. E. MEASUREMENTS OF SPURIOUS RADIATION (Paragraph 2.993(a) (b) (2) of the Rules) Measurements of radiated spurious emissions from the Eclipse were made with a Tektronix 494P spectrum analyzer using EMCO 3121C calibrated test antennas using substitution comparison. The transmitter and its integral vertical antenna were located in an open field 3 meters from the test antenna. Supply voltage was from a fresh set of batteries with a terminal voltage under load of 10.2 Vdc. The transmitter and test antennas were arranged to maximize pickup. Both vertical and horizontal test antenna polarization were employed. Reference was power at the carrier frequency. The measurement system was capable of detecting signals 100 dB or more below the reference level. Measurements were made from the low…
