you are at 5200 ft though . i dont think . it will be powerfull enough. at that alt with the 91 in a ucando.. the flip is $179 at tower now ive seen it as low as 169.. you can always go with a U-cando 40 but. me personally have flown it and like the 60 better.. my u-can-do with the 91 4 stroke flys great but i am itching to fly it with more power too. I understand it is like night and day with a YS110 on it. but i am on a waiting list..
it was just a suggestion with the flip.... oh yea if i got a flip im putting my 91 from my ucando on it
