RE: Let's talk DX18 here!
Pete,
The DX8 programming for the Mystique will work just fine in the DX18 if you select Acro mode.
If you want to learn how to set up a full-house glider in a competitive pilot's manner, use Sherman Knight's guide. It's 30-some pages just for setting up a simple glider like the Mystique, but it explains every little nuance in a way that only somebody intimate with the development and glider piloting could do.
