Operating Instructions Introduction 3. Congratulations on your choice of the MULTIPLEX COCKPIT SX radio control system. Safety Notes ! These operating instructions are an essential part of the product, and contain important information and safety notes. Store them where you can refer to them at any time. Be sure to pass them on to the new owner if you dispose of the product.
COCKPIT SX Capacity [mAh] ≥ no. of servos × 200 mAh rapid changes in temperature (e.g. warm car : cold environment) can result in condensation inside the transmitter. Damp has an adverse effect on the working of the transmitter, and on all other electronic devices. If you detect damp in any electrical apparatus, cease operations immediately, disconnect the power supply, open the case (if possible) and allow the device to dry out (may take several days). Carry out a careful check of all functions when dry.
Operating Instructions When operating the model: • If you are a beginner at controlling models, please ask an experienced model pilot for help initially. A Trainer (buddy-box) system is very useful for the first few flights • Fly your model only at a suitable approved site. • Don’t fly or drive your model towards or above spectators. • Never carry out risky flight / driving manoeuvres. • Know your skills and your limitations: please don’t over-estimate what you can do.
COCKPIT SX Standard receivers (without IPD or similar): If your receiver does not feature signal checking / correction (e.g. Pico 3/4, Pico 5/6), slight jitter close to the range limit is acceptable. MULTIPLEX Modellsport GmbH & Co. KG therefore accepts no liability for losses, damage or costs which arise as a result of the improper use and operation of the product, or are connected with it in any way.

This is not easy, especially for the inexperienced pilot.
Operating Instructions Differential in practice: The degree of differential required for a particular model is usually stated in the building instructions. If this is not the case, we suggest that you set the downtravel to around half of the up-travel, i.e. 50% differential. Aileron differential is not usually required with symmetrical wing sections. Many radio control transmitters offer aileron differential as a value which can be varied by the user.

If you are setting up a new model, the values are set by default to -100% / 100%, i.e. the aileron travels are the same up and down.
Operating Instructions Moving to the H ->Q menu: 4 to MENU, r (SETUP appears), 3 to MIXER, r (TH->S4 appears, e.g.), 3 to EL->AI, r (current value flashes) To ensure that the model is as responsive as possible, the down-aileron travel is increased to the same value as the up-going aileron when the SPOILER control is operated.
COCKPIT SX Input: Throttle TH -CO This input can be used to compensate for an unwanted tendency to climb when the throttle is opened. A brief press r on the 3-D digi-adjustor concludes the process. The flashing ceases, and the values are stored. Input: Spoiler SP -CO This input can be used to compensate for pitch trim changes caused by airbrakes, Butterfly (crow) systems or “raised aileron” spoilers. 14.7.
Operating Instructions Input: Spoiler SP->F If you wish to raise the inboard flaps to help the model descend, or lower them for a Butterfly (crow) system, you have to dial in this input. The default setting is 0% (no deflection). Here there is only one value, as the inboard flaps only move in one direction from the neutral position (Î 14.5.3.). Input: Aileron Q ->F The Aileron input has two values which have to be entered. If you are setting up a new model, both values will be set to the default 0%, i.e.

The flashing ceases, and the values are stored. 14.8. V-tail If your model features a V-tail, the two servos must be connected to receiver outputs 2 and 3. 2 Move the Spoiler control (stick or right-hand slider) to the “Spoilers extended” position. In section 14.3.4.
Operating Instructions ! Check the position of the D-R switch There is a separate value for each switch position. If you set the same value for both switch positions, you do not need to think about the switch position when you operate the model. If you have activated flight phases, … there are two values for Dual Rate in each flight phase, i.e. a total of six values. In this case please take particular care when entering the values, because it is quite easy to forget or overlook one value.
COCKPIT SX Note: observing the effect of EXP on the model EXP does not influence the centre position or endpoints of the control surfaces. If you want to see the effect of this setting on the model itself, you have to hold the associated stick at half-travel.

COCKPIT SX For each of the seven servos you can adjust the following parameters: When you set up a new model, Throttle Check is always active (THRCHK = 1). We recommend: Don’t switch Throttle Check off unless you are sure that it is not dangerous to switch the model on “with throttle” (unpowered model, glow motor, speed controller with power-on guard).
Note for V-tail models: It is not necessary to check the direction of rotation This is where you set the travel separately for both directions of rotation. If your model features a V-tail, do not check the direction of rotation of servos 2 and 3 (elevator / rudder) at this point. The directions of rotation can only be checked and adjusted once the V-tail mixer has been activated (Î 15.7.1.). a. 15.4.2.
COCKPIT SX Input: Elevator This input alters the position of the ailerons when the elevator stick is operated, and it can be switched on and off using the S3 switch (SNAP). The default setting is 0% for both values. This function is termed SnapFlap, and it supports the elevator function, e.g. when pulling tight turns (F3B) or for aerobatics (Î 15.5.4.). Aileron travel and differential Menu: (MIXER) AI->AI In this menu you set the aileron travel in the up and down directions.
