I had a crap load of standard servos laying around and didn't feel like buying 4 mini servos for the tail so i just took the dremel out and made the servos holes to fit the plane for 4 standard servos and it came out fine...
I'm all for using what ya got but this will add about a 1/4 pound to an area of this plane that is about 12" behind the CG. I guarantee you'll be adding lead to the nose to balance. Not the end of the world but something to consider.
