Just got back from the first flying session with the Cermark Ultimate 40. Set it up as reccomended, throws, expo etc My honest opinion well it flies fine on the high rate settings but is a tad sluggish at low rates, maybe my example is a tad nose heavy as i installed an OS FL70 which according to the manufacturers figures is 90 grams heavier than an OS46. Flies well at below half throttle on 12x7 APC, didnt throw it around much as had a bad attack of the glitches and it unnerved me a little, think I'll slip PCM reciever in it before next flying session. Overall I think Im going to like it, takes off and lands real sweet not as twitchy in roll as I expected and sure looks nice purring past at low level.
