The 1.60DZ is the absolute best motor I have ever run, bar none. I, too, am a YS convert, having flown an OS 1.40RX for several years, and Webra before that. Everything pales in comparison to this motor, IMO. I'd love to get my mitts on a 1.70DZ, I guess that's for next year.

As far as setup, I'm running an Asano header and pipe, 30% Morgan Coolpower, and an APC 18.1x10. I want to try some other props this fall and see how they do, more specifically a 15x11 4-blade, and maybe a 17x12. The 18.1x10 is an awesome prop, but you have to be careful that you don't slow down too much. Very rarely do I ever bring the throttle down to idle on a downline as the prop brakes too much and will slow down.
