4. The mc3030 allows easy adjustment of differential and control sensitivity with a single point of adjustment for each but to take advantage of this you need to be systematic in the way you set up the model 1 When setting up on the bench turn off DIFFER by setting to zero or disabling it and use the Servo Travel screen to obtain maximum servo travel subject to the mechanical limits of the hinges and make sure there is equa movement in both directions 2 If differential is required simply dial in a suitable figure say 50 for the Aileron s DIFFER attribute using the Control Setup screen for Aileron The downgoing movement servos will now be 1 2 the movement of the upgoing movement If you find that the upgoing aileron is affected instead of the downgoing reverse the DIFFER value Send feedback to mc3030 rc soar com Page 19 Programming the Multiplex Profi mc3030 3 During flight trials you can reduce the control movement of all the aileron servos together using the Control Setup screen and the TRAVEL attribute Or you can change the differential for all servos at once simply by altering the DIFFER attribute Limiting Servo Travel Weve already seen in the examples how to set up V tail mixing One further consideration is the effect of applying rudder and elevator together If the individual controls have a large amount of movement then it s possible that applying both rudder and elevator together will cause one contr

15. three possible mixing schemes for all your servos Fortunately not the reason follows from the previous section Say you create a user mixer with Elevator and Rudder inputs assign servo 1 to it then add Spoiler to the list of inputs Remember that servo 1 will not see a page for the new Spoiler input until you re assign the servo to the user mixer What if instead of reassigning the first servo you assign servo 2 to the mixer This leaves servo 1 with the original before the changes mixer inputs and servo 2 with the new combination of inputs including Spoiler Using this technique one mixer can provide a different mixing scheme for two three or even all your servos call this technique re cycling Just to recap 1 After you create or alter a user mixer you must assign a servo to it to make it effective To reinforce the point the system takes you straight to the Assign Servo screen when you hit the M key in the UserMix screen 2 You can recycle a user mixer by changing the inputs and assigning it to a different servo 13 t s even available in supposedly EMPTY model memories You can demonstrate this as follows 1 Make a copy of one of your model memories using the File Copy screen and call it say TEST 2 Goto the UserMix screen and define a user mixer say USR MIX1 with say Elevator and Aileron inputs 3 Delete the TEST model memory using the FileCopy screen Note that the model name is auto
