I absolutely love my DZ 140 but Drac is correct that the FZ will be easier to set up and close to the same power as the DZ. that being said my DZ is mounted on an airplane that honestly is a bit of a hangar queen and does not see that much flight time. I brought it out on Friday for the first time in 6 months and she fired right up and needed no adjustments. Between Friday and yesterday I logged 6 flights without as much as a missed beat. I run a 16x10 three blade CF prop and 30/20 all synthetic fuel.
