I have a DP 330 with approx. 15 flights so far & this is the best big aerobatic I have owned to date,I cant say anything bad about it.I also have a GP PW 300 & the 330 still flies better in every way,it crawls when landing & very very easy to take off.It does perfect knife edges the whole length of the field with hardly any input and rolls very fast & very axial as well .I have a Saito 180 in mine & is plenty of power in my opinion -there will no worries about aileron flutter or stressing the air frame apart.I am not into the hover & 3D thing much but I have tried the 330 out & it has enough power still to execute them successfully.I am currently working on a way to be able to open/hinge the canopy to one side like the full scale version hence making wing attachment uneventful cause that is my only complaint about this plane .I do not like the idea personally of wing retention with dowells/wing bolts thru the wingtube
