Flight modes

In the previous part you have created basic model configuration and it can be assumed that servo deflections are sufficient and with a correct direction. Administration of flight modes is to be found under the item Fine Tuning/Flight Modes – Flight Modes. Here you can set up several flight modes according to your habits, however it is possible to keep the default one. In the picture there are 5 modes that have been created depending on the task or phase of flight. Si and Sa have been selected as an example of activation switches of flight modes, both of them are three-position. Priorities are used when switching between the modes, Landing and Start have the highest priority. The position of Sa switch is set by the pilot before the flight, which determines the desired configuration for the flight in given competition task (thermals, distance or speed). With Si switch the phase of the flight is then selected (start, landing and the task selected by Sa switch). Notice that at every mode certain delay is set - it enables smooth transition between phases. The flight mode Thermic is only alternatively named Default mode. |

For trimming of the elevator it is possible to use standard trim buttons, however trim can possibly be assigned to any three-position (preferably centered) switch – see the picture. Only elevator and rudder trims are active - firstly it is a precise composite model without twisted wings, secondly if there is a v-tail, frequently the rudder is not trimmed. Aileron trim is global for all flight modes, in the contrast elevator trim takes different values in each mode (respectively in the picture group FA is selected, which enables having identical trim setup for one and more flight phases). |

You can set up specific camber of the trailing wing surfaces for each flight mode - see menu Flight Mode Trim. In the picture functions of ailerons and flaps/brakes for Thermic mode are set up for downwards deflection, contrarily the elevator is slightly tighten up. |

Set up Dual rates and Exponential settings according to your habits. Again there is a possibility of separate configuration for each flight mode. |

It is also recommended to set up certain aileron differential. When flying at high speed, the ailerons and flaps are in neutral position or they are deflected rather upwards, it is preferable to use smaller differential (respectively 100% deflection upwards and 100% deflection downwards). If flying at low speed or in thermic, when the profile shows a high lift, the value of differential is generally higher (e.g. 100% aileron deflection upwards and 50% deflectioon downwards). Tuning on appropriate value of differential requires a lot of effort, however to make it easier it is possible to alter it during the flight via any proportional driver (see P8 in the picture). The real value of the differential is shown in the brackets in the picture. |

Activating of Butterfly function is advisable only for Landing mode, this way you prevent possible unintentional activation of this function in other flight modes. As the driver, the throttle stick P2 is usually selected. In Ailerons/Flaps Adjustment and Elevator Adjustment enter required deflections at fully activated brakes, when adjusting the elevator it is also possible to adjust multipoint compensation curve. Negative values for ailerons mean upwards deflection, positive values represent downwards deflection. |
