No - not crappy as such. Smoother at higher speeds. Shame is that bits start falling off at about 440. Ailerons are apparently only taped on.
Edit: bits falling off seems controversial. Some guys saying 440 some say 480 some say not even at 500. Mine have been falling off from La7s etc not speed.
Pilot wounds seem to be the go from the talk, but its not a flying bbq.
I took one up to 12k, pulled into a snap and spun all the way down. Power, controls, flaps all make no diff. I didn't try differential engine power. Might be worth a try.
