Not sure I understand what you mean by top right and top left on the transmitter when it comes to control.

In answer to your question about the turn before it sets off, you need to set up the trims on the transmitter. If you look directly below and to the side of the sticks there should be a little button or slider that allows you to set the trim (or bias) on that channel. It takes a little work experimenting to get it all set up well.
