Hi Darticus,

The normal setup for a three channel mode 1 plane is to put the rudder and throttle on the right stick, rather than aileron and throttle on the right stick (as you would for a 4 channel).

The transition once you are ready to move off your trainer is easier because of this, not harder. In a trainer with high dihedral the rudder makes the plane roll in a *similar* fashion to the way the ailerons would in a 4 channel. In contrast the rudder on more advanced planes wont make the plane roll the way it does for the trainer - it will just sort of shunt the nose in that direction but wont make the plane roll.

If you practice with your trainer you will find when you transition that the ailerons will make the plane behave similarly to your rudder in your 3 channel.

HTH.

Cheers,
Oz.
