I had the OS 120 AX on Wildcat 20% with APC 17x4W prop in Funtana x100 and Showtime. The Funtana was 9.4lbs, the showtime was 10.3lbs (both dry)....in both cases the plane could pull vertical like the space shuttle. In the funtana (being 1lb less), I noticed a huge diff in the hover. In fact, it was hard to get "into the hover", as the power/weight ratio made the funtana "float"...where as showtime was heavier with less wing area, so when you pulled "full up ele", the showtime went into the hover better. But once the Funtana was in the hover, it held at 1/3 power. When you nailed it.....it just pull out of sight in less than 5 seconds . With the NP at 8.5lbs, it will be amazing to see how this pulls out of hover. I post pics of my showtime hovers with 120AX
