Where do you put them

[handthrottle]

Hi all
coming to the end of building my 450 v2 (sloooooowwwwww). Would like your views on where to put the receiver/battery/speed controller. I have read threads about keeping this away from that/that gets hot....etc etc. Might as well get it right the first time. Appreciate your time.

receiver at the back on the lower tray, battery on the front upper tray, speed controller underneath upper tray and gyro below boom holder (upside down)
