I use cross trims and flight modes just like Jamie mentioned above. I highly recommend flight modes, cross trims, and flight mode trims. Just be sure you set it up correctly before you fly.
The small trim buttons were hard for me to feel till I found these "Trim Hats." The trim hats attach to the buttons with small circles of double sided auto trim tape. They are easy to attach and very solid feeling. With a strap or tray I can just fly with my right hand and trim roll and or pitch with my left hand. The trim hats are very easy to feel and they work just like a trim button on top of a fighter stick. May not be for all but I really like them.
