I've had 3 of the 2.6's and 1 3.0. I really liked the 3.0 best because I could fly it slower between maneuvers during the unknowns and have time to think and relax ! I figued out how to do the same with a 2.6 about the same time some guy had a fistful of cash to buy the plane!! Oh well! DA100 witha MSC 26-12 prop.
Both the 2.6 and the 3.0 required the same amount of mixing.....Not much!! I really had my 3.0 dialed in well when a radio failure at the Tucson Aerobatic shootout did the plane in!
I'll be on my way to SF for a new 3.0 in a week or two.($$$) Everyone I Know here on the west coast,including myself that flys a 3.0 would by another in a minute.... If you're a middle-aged gent such as myself,the 3.0 is MUCH easier to see!!!
I'm really looking forward to Big Yellow2!!!
