josh what long blades are you giong to use? is it the 325 CF blades? this might hit the tail prop since it too long... I have'nt tried it yet on the DF60 but I have a 325 set of blades here.. I tried to compare it with the existing 288mm and this blades are long.. good for the 450 size TREX but too long for the Df60 even with the longer boom... just be sure of it before you fly it you might get blade strikes...
