C. Earnest:
For the year and a half that I have been flying by DP Extra with a Taurus 3.2, I felt the same way you did.

However after losing my DP Edge on its maiden flight due to flutter, I am questioning our wisdom. Was 1/2 throttle and straight & level flight making minor trim changes. Blew the gears out of both servo's.

Until it happens to you, it is easy to think the way you do and I used to.
