Yes this is the std spot for the servo in the lipo chassis, there are about 9 Preds at my local club and they have got some neat installs in this std positon.
I know Rebels X11 has had the servo moved back nearer the motor for more Esc room. As the HW speedo isnt that big I reckon I can squeeze it all in!
Check this for a neat install:
