thats good to hear that it performs well with the ys110.Mine should be awsome with the ys120 I guess I'll pick up a 16x4w.
do they make a 17x4w? Thats one I've got to look for as the new carbon gear has plenty of clearance
By the testing I have done and all other thrust tests (empirical) that I have seen, a good APC16x6 will out pull the APC16x4w and the APC17x4w and the APC16.5x5 on a typical YS110. Will these other props work?--Sure they will, I have tried them and they all feel about the same to me.
I have had a YS110 on a 8.6 pound plane (E.F. YAK) and found it to be adequate (at sea level). I would be wanting a bit more go go on a 9.5+ pound plane, although many are happy power level.
I like my F90 enough that if I could find one of those light ones or a light 100x (8.3 pounds with a 26oz power package) I would buy it.
