I have the 33% Ultimate and my flying buddy has the 27% . I have flown his and it fly's great. He has a DA 50 in his. I have a ZDZ 80 in my 33% which fly's a lot slower than the 27%. The only problem he had was the small tabs that hold the cabanes pulled out in one wing panel. Other than that it's a great plane and a good value. Both planes are built the same, with the exception of the flying wires which are not used on the 27%. It takes me 30 minutes to get my plane ready for flight.
