FM/QPCM Acro / Glider Heli Three in One Made in the Philippines English Manual Table of Contents Introduction to the Optic System Congratulations! [. . . ] 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. It is sometimes used for helicopter tail rotors. The Optic allows you to set exponential for ailerons, elevator, and rudder. 2. To set exponential for channel 1, move the arrow by pressing the Cursor Right or Left keys repeatedly until the arrow is over the channel number you want. Now switch the appropriate switch up or down, noticing the position of the arrow. You can set two values of exponential, one for each switch position. By pressing the Data +Increase or -Decrease keys, you can add or subtract from the numerical value displayed. Note that you may pick a value anywhere from -100% to +100%. If you quickly want to get back to the default 0%, press the Active/Inhibit (Clear) key. You should understand that you won't see changes in your model's servo response unless you move the sticks. To get a feel for how exponential works, just hold partial stick and switch the Expo on and off (one side of the switch should be set to zero expo). You'll see how it affects the servo travel. The values you set for exponential are highly dependent on both the model and pilot's preference. I normally recommend a start value of about -10% to -20%, and many test flights, slowly increasing the number until things are "right". Obviously this depends on the pilot and model so go ahead and fly it with Expo only on one side of the switch, turn it on and off during flight, and change things to suit yourself.
