OK, I'll try and help, as the Cularis has seven control surfaces you would normally use a 7 channel system to get the best out of it. But you could get around it by either of the follow:
1) put the ailerons on a Y lead, but you will lose the ability to have spoilerons or set aileron differential. But allows you to put the flaps on different channels and use the radio to set up the flaps on separate channels
2) use an inline servo reverser and Y lead the flaps into one channel, so both flaps move in the same direction to the flap control.
While the Mulktiplex manual will show the set up with a Multiplex radio, I have set up similar gliders on other radios.
