I did a quick search for your radio's manual and you are right it's pretty weak. The on line version says page 16 and on are for plane programming but page 17 is really page 14 and goes right back to talking about heli set up.

The important thing to note is that your radio MUST be configured through a computer with the provided software. There is a (slight) chance that once you open the software you will find a page on how to set up either a delta wing or flying wing configuration This will give you the combination of elevator and aileron on the controls on the trailing edge of the Typhoon.

Best of luck
