[. . . ] The control throws should be set up so that the "end points" are as near to 100% as possible. If the EPA values must be set below 70% or above 120% to get the desired throw, you should strongly consider changing the pushrod connections so the values can be set closer to 100%. (When the EPA is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is approximately 40° and approximately 55° for channels 5 & 6. ) To set the end points: 1. Enter the programming mode and use the MODE key to access the "EPA" screen. The channel number being adjusted will the left side on the screen and the "%" symbol will be flashing. To change the RIGHT aileron throw move the aileron stick to the right, then push the DATA INPUT lever up or down to change the value and the throw. Move the stick to the left and use the DATA INPUT lever to change the LEFT aileron throw. Use the SELECT key to display the other channels and set the other end points. Notice that moving the stick (or switch or dial) from one end to the other changes the value displayed and the position of the arrow for that "end" of the control input. TRIM Trim Settings There are four trim levers ("trims") on the front of the transmitter. Three of the trims are for adjusting the neutral position of the aileron, elevator and rudder servos. The intended use of the trims is to make small servo adjustments, in flight, to get the model properly "trimmed" (so it will fly straight-and-level). Because the trims are intended to be used while the model is in flight, you do not have to "enter the program" to adjust the trims. Simply push or pull on the trim levers while flying and the neutral position of the servos will shift. Keep in mind that you should start out with the control surfaces centered when the servos are centered and the trims are "zeroed" (or near zero). Operate the controls to make sure the servos respond in the correct direction. Place the servo arms on the servos so they are perpendicular to the pushrods (see page 5). Adjust the length of the pushrods until the control surfaces are centered when the servos are centered. Note: The throttle trim affects the throttle servo only when the throttle stick is below "1/2 stick. " This way, the final closing of the carburetor can be adjusted without affecting the servo throughout the rest of the range. To adjust the trim settings: Once the servos and control surfaces have been connected and the control throws have been set using the end points and dual rates, get the model airborne. Adjust the trims as necessary to get the model to fly straight-and-level. If much trim is required on any one control it is a good idea to readjust the pushrods so the trims can be returned to neutral (zero). Adjusting the trims with the trim levers changes the servo's position in increments of "4. " If finer adjustments are required, land the model, then enter the program as described below to adjust the trims in increments of "1. " 1. [. . . ] Two models can never be operated at the same time on the same frequency-no matter what the modulation (AM, FM, PCM). If you turn on your transmitter while another person is flying on the same frequency, a crash will result. NEVER turn on your transmitter until you have permission from your instructor, and until you have possession of the frequency clip used for frequency control at the flying site. If you are an inexperienced pilot, be certain your flight instructor performs these following checks with you. [. . . ]
