Profi - Mixers 1 – Mixer overview The above schematic simplified representation of the Profi mixer structure, key points to note are - There are two control mixers which can have two inputs, or a control can be mixed with itself, the mix percentage can be flight phase specific.

Profi – Mixers 2 -Defined Mixers The Profi includes 2 defined mixers which are non-editable, an aileron differential mixer and aileron-rudder combi mixer. These are always available and are setup by entering the Mixer settings menu (GHI2) The aileron differential mixer is used to set the aileron differential to reduce adverse yaw and/or fine tuning the roll control on an aerobatic model to give a more axial roll.

Profi – Mixers Servoside Mixers The servoside mixers are the key to getting the best out of your Profi and are significantly different from the control mixers found on most other radios. In the Profi the mixers are created either from scratch or using the supplied editable templates and then assigned to outputs. Each mixer can have a total of 8 control inputs and each model memory can have 5 servoside mixers which can be used multiple times, i.e.

Profi – Mixers 3 - Servoside Mixers Here is an example of setting up the supplied flap mixer template, first in the mixer definition screen The 3 column determines the mixer curve for the representative input, in this example Flap is the primary input to the INNER FLAPS and is asymetrical with both surfaces moving in the same direction, in the mixer Menu (GHI3) the flap travel can be adjusted for reflex and thermal, Spoiler input is with a single sided curve with offset, so the position of the flaps is offset to allow full servo movement to be utilised, Aileron input...

Profi – Mixers 3 - Servoside Mixers This is an example of the mixer inputs in the Mixer menu (GHI3) for the FLAP_INNR+ mixer Flap control input has been limited to In the spoiler input , with the spoiler 4% in one direction and 12% in the control (e.g.

Profi – Mixers 3 - Servoside Mixers Here is an example of setting up the supplied aileron mixer template, first in the mixer definition screen The 3 column determines the mixer curve for the representative input, in this example Aileron is the primary input to the AILERONS+ and is symmetrical with both surfaces moving in the opposite directions (2), in the mixer Menu (GHI3) the aileron travel can be adjusted (Differential is best adjusted in the specific differential mixer covered earlier) , Spoiler input is with a single sided curve with offset, allowing the ailerons to...

Profi – Mixers 3 - Servoside Mixers Here is an example of setting up the supplied aileron mixer template, here are the settings in the mixer menu (GHI3) As expected the aileron input is always on and set too 100% in both directions, with differential being set in the aileron differential mixer Although Flaps and Elevator inputs Spoiler input is set at 40% and is active in...

Profi – Mixers 3 - Servoside Mixers Apart from the standard curves the Profi gives you the option to create a bespoke curve if you require, here’s one made up to mix rudder control into nose wheel steering In the mixer definition menu (ABC1) a new mixer called Wheel+ was created, which was assigned to the nose leg servo channel in the servo assignment menu (JKL4), an input from the rudder was added to use curve 1 In the mixer menu (GHI3) opening the Wheel+ mixer and rudder input...

Profi – Mixers 4 - Control Mixers In addition to the other mixers the Profi provides two control mixers and these are found in the Mixer Menu (GHI3) as Ctrl. Mix 1 and Ctrl. Mix 2, entering these brings up the screen where the controls to be mixed can be specified and set up.

Profi – Mixers 5 - Other i) Using Fight Phases to fix mixer inputs An alternative to activating inputs in each mix is to us the settings in the controls menu (DEF2) for flaps, spoilers, aux, controls etc to lock those controls in different flight phases as follows. This locks the control and could be used to make it effective in say flight phase 1 and 3 and not in 2 or 4.
Page 20
Royal Pro/Sx – Mixers 5 - Other ii) Using Flight Phases to adjust mixer inputs If you wish to have a varying amount of mix depending on what flight phase you are in, e.g. say you wish to have more flap movement in the launch phase and less in the thermal phase this can be accomplished by using two input lines in the mixer definition screen activated by separate switches and then entering different values in...
