Not a good setup. Too much crammed in here and with both ESC's in this small space @ >175 watts each, is a recipe for disaster! Notice the single conversion rx next to ESC's, not good! This could glitch out causing a crash.
Here is a better way. Each ESC is mounted in the L\R air intakes and gets plenty of airflow. This also moves the BL controllers away from the receiver which is mounted in the forward cavity by its self.
