I like the APC 16x6 the best for the mighty 110. I also use the 17x4W but it doesn't have as much thrust by about 1 lb. Also, spool up is much slower than the 16". But for some reason it's much easier to hover with. So...if I want to hover I use the 17x4W, but for everything else the 16x6 is better.

thanks
