Wow! I run my WM Zen-50 with the aforementioned YS-63 on a 12x7 APC and it performs wonderfully (At least as good as I can do...) I have my flight pack back BEHIND the servo tray so the CG is back where I like it [X(] I do think your fast landings are because of the weight of the 61 also though, the plane likes to come in fast-

When I first got mine I came in WAY too fast until I realized, as someone mentioned, that slow flight could be very slow as long as you are on the power when needed- Mine now comes in tail down and I can touch the tail-wheel first, and not be in danger of a pancake stall-

I absolutely LOVE this plane! It definitely flies better than I do- [X(]

Great advice above- just thought I would throw my hat in cuz' I have a similar combo- And yes it CAN hover with the 12x7 APC
