FM/QPCM Acro / Glider Heli Three in One Made in the Philippines English Manual Table of Contents Introduction to the Optic System Congratulations!You now own a Hitec R Optic, an extremely versatile radio control system that may be effectively used by both beginning and master pilots. The transmitter may be programmed for aircraft/gliders or helicopters, all with special mixing functions, so it can accommodate many model configurations. [. . . ] If the servo is not buzzing, leave the setting at 100%. Flashing Optic Aircraft Controls and Switch Assignments - Page 26 Airplane Model Function Descriptions - Page 27 Airplane Model Function Descriptions 3. Use the Data +Increase or -Decrease key to choose the amount of dual rate for that switch position. You may set the travel for both sides of the switch simply by flipping the switch to the other position (the arrow will also switch sides). If you wish to return to the original 100% value, press the Active/Inhibit (Clear) key. Press the Cursor Right key to move to another channel you wish to input dual rate settings. Repeat the first three steps for the dual rate settings on the remaining channels. Return to the regular operating mode by pressing the two Edit Up Down keys simultaneously. Enter the programming mode by pressing the two Edit Up Down keys (the two keys on the far left) at the same time. Press either Edit Up Down key until the EXP menu appears, as shown. Airplane Model Function Descriptions subtrims are large values, the servo's full range of travel may be restricted. Use the Edit Up Down keys to call up the STRM window. T. CUT - Throttle Cut (Engine Kill) Function The Throttle Cut function provides you an easy way to stop the engine by simply pressing a button with the throttle stick at idle, which commands the throttle servo to move a prescribed amount. The throttle servo moves to the selected cut position when the Cut button is pressed and the throttle stick is below 50%. Setting up the Throttle Cut function Flashing Flashing EXP - Exponential You may be new to exponential settings. "Exponential" refers to a mathematical function where the curve grows steeper the further away from center it gets. Expo is a way to get the effect of dual rates without having to flip a switch. The figure below will help explain this concept. Servo Response Much less response around neutral(compare with Normal line) Normal linear response 75% 50% 25% 0% (Linear) Increasing exponential (shallower around neutral) Stick Motion Exponential gives smaller response for same stick motion around neutral You will notice that exponential has a smooth curve. For this reason it is possible to have low sensitivity at low stick angles (like dual rates), and yet have full motion at full stick deflection. The Optic allows you to have two different values of exponential, chosen by the same dual rate toggle switches on the transmitter, described earlier. You might want to set a dual rate at one switch position with zero exponential, and an exponential value with 100% dual rate at the other. Then you can switch between them in flight and decide which you like better. Later, you can combine both dual rate settings and exponential on a single switch setting. There are really two kinds of exponential, "positive" and "negative. " Negative exponential is the one shown above, and the type of expo most commonly used, where servo movement is softer around neutral. Positive exponential is where the servos are very sensitive around neutral and soft at extremes. [. . . ] Center this lever before you set neutrals or input throttle curves. Max Pitch Min Pitch Changing the Hovering Pitch value moves the pitch response above or below the straight line Low Hover Throttle Stick Motion High Menu Descriptions - Helicopter - Page 54 Menu Descriptions - Helicopter - Page 55 Helicopter Flight Trimming Chart This procedure assumes helicopter is trimmed for hovering. If any changes are made, go back over the previous steps and verify, or further adjust as necessary.
