  • Page 53: Digital Trim

    Transmitter Digital trim 3.8.1 Overview "Trimming" refers to the adjustment of the model aircraft to fly straight and level when you leave the sticks exactly at centre. Digital trim has two essential advantages:  The physical position of a conventional trim with trim slider corresponds to the actual trim value, while digital trim buttons do not.

  • Page 54: On-Screen Trim Display

    Transmitter about 0.8 sec., the trim value changes continuously until you release the button again (AUTO-REPEAT function). When the trim reaches centre, the AUTO- REPEAT function stops briefly. Each trim increment is accompanied by an acoustic signal. On reaching the trim centre and on reaching the maximum trim range, specific acoustic signals are emitted to alert the user.

  • Page 200: Calibrating Servos: Setting Centre And Maximum Travel

    Creating and customising models If you move the collective pitch stick slightly from the neutral position before pressing the REV/CLR button, the servo will jump to the new position when you reverse it. This is an easy way to check that you have selected the "correct" servo. 6.
  • Page 201 Creating and customising models First, perform a hardware calibration: Press the button. This generates the "true" centre, without the influence of the trim or mixer inputs on the servo. If the servo is not in the desired centre position at this stage, it is essential to correct the control surface position mechanically (by re-positioning the output arm on the servo, or otherwise adjusting the linkage).
  • Page 202 Creating and customising models Setting the maximum servo travel (control surface travel) At this point, set the maximum required value for blade deflection; this is generally the auto-rotation value. The smaller values required for normal flying can be set for the individual flight phases in the ControlFunctions menu under Collective.

    Creating and customising models 8.2.8 Throttle Does not apply to the FUNCOPTER template! For throttle-controlled helicopters, the simple throttle setting of fixed-wing models is used. See chapter 5.4.2 on page 117. The Throttle control function can be adjusted using 7 curve points or using a fixed value when the electric power system operates in Governor mode.

  • Page 208: Setting The Collective Pitch Curve

    Creating and customising models Sometimes, it can be useful to operate the throttle directly without any restrictions. To do so, assign a switch to the CS/DTC switched function as described on page 104. When this switch is in ON position, the limiter controls the throttle directly.

Otherwise, the transmitter always operates in Phase 1. For each flight phase, you can customise the control characteristics on the transmitter according to the requirements of the model (e.g.

  • Page 218 Glossary of technical terms Differential Indicates the percentage by which the travel distance of the control surface down is reduced relative to the travel distance up; if the differential is set to 50%, the travel distance down is half as great as the travel distance up. The higher the % value, the shorter the travel distance of the control surface down.
