Is this plane a 4 channel plane with ailerons? You can try setting the throttle at 3/4 open (up) and flying only using the right stick (elevator and ailerons). Once you are able to get the plane away from the ground you can try using tiny rudder inputs to get a feel for the left stick. I don't really suggest flying without the rudder, but if you are not on a buddy box and not with a trainer, flying with only the elevator and aileron might be the way to go until you get the plane in the sky long enough to take a breath.

Try sitting on your couch with the radio (off), and imagine the plane rolling in either direction, and control the stick accordingly. Imagine take off (remember, set the throttle at 3/4 right from the bat and leave it alone) the plane rolling, and you gradually increasing elevator until the plane just gets off the ground. Keep the elevator right where it is. Imagine the plane rolling a little to the left, correct it, with very, VERY small aileron inputs (push the stick a tiny bit to the right and back to center, do it again, little push to the right, back to center, until the plane is level).

Yeah, this sounds hokey, but you need to get some time with the radio in a state where you are not in a panic, are breathing, and your heart isn't trying to leap out of your mouth.

When I say small inputs, you are only giving maybe 1/16 to 1/8 of the possible range of the stick. A very small move on the stick will have an effect. If you are trying to roll in one direction, and don't roll far enough, you can roll a little more. If you roll too much right from the bat, you go into a state of recovery, and will have the tendency to over correct. Little movements will buy you VALUABLE time and save you from having to react.

Hope this helps.
