Yes...the auto hub and shaft are the best $$$ you could spend. Like you...I've shelved the DD and went back to stock. I'll be ording a few N30's here soon. Tower still owes me a good CN12, but I'll just sit on that for a while. Stick with what works.

The Main Gear / Shaft is the best bucks I've spent so far. The E Flights were bending at the slightest smack of the blades this thing is tough. E Flight will miss my 6 bucks a week. I tossed the 2 new motors for the DD in a box and went back to the stock set up. My Pro is flying nice. Monday maybe I'll fool around with the DD again.
