I have been flying the UCD 60 for 2 years know and I have been frustrated trying to learn 3D with it. Maybe the 46 is different. The spad 3DT is easier to harrier, , elevator, hover, but as far as normal flying stinks. I can only get the the UCD 60 to harrier downwind, but as soon as I try to make a turn or if I start making a little correction on the aileron it starts wing rocking like crazy. Maybe its just me as a pilot, but there has to a better plane out there.
