Here is the catch 22 about the whole flying without help thing.
Can it be done? Yes absolutely and an airplane like the apprentice along with a good sim makes it all the easier.
But the catch is no airplane, including RTF, are trimmed out properly so not only are you trying to fly an airplane with no experience except the sim, you are distracted by the need to trim the flight controls.
Try this on your sim, have someone else move a couple of the trim switches a few clicks in random directions and without looking at the controller take off and see what happens and if you can adjust the trims by yourself or even fly with the trims off.
At the very least have a friend with you on your first flight to adjust the trim switches for you and make sure he knows what switches are what so when you say I need some right aileron he will know what to do.
Better yet find an experienced pilot to assist you and trim your airplane for you.
