I tried out the APC 15x6 today ...

I like the 16x4w better for hovering, but honestly there are probably others that would prefer the 15x6. On the ground, the 15x6 sounds like it spools up a little bit quicker but I like the throttle response of the 16x4w in the air in a hover. Both have similar "torque roll effect". TR'ing masters might be able to tell a bit of a difference but I was not able to tell much of a difference in that respect. Both take the plane ballistic on command. The 15x6 seems to yield faster forward flight during normal flying ... but hey ... who does that with the UCD anyway??? <grin>

By the way ... I've named mine "3D Xtreme" and put graphics on it to that effect. I just cringe at the sounds of "U-Can-Do 3D" name!!

Hope everyone is enjoying theirs as much as I am mine...
