I was flying my little .40 size kangke extra last weekend, I am just learning to hover. I was about 30' up in a hover & it started to fall out, I hammered down & went straight up like a rocket. A couple of guy's in the pits hollered "what do you have in that thing, a 120??" I responded "no, a ys63" HeHe. There jaw's dropped to thier knees in disbelief. I also have a funfly with a saito 72 & the ys63 will kick it's *****.
