"The EDF version fuselage is being prepared, with the base formers fitted in place after adding the switch cut out and nose door servo mount as in the P20 version. I plan to install the ESC in the area behind the cockpit, in the spine section so added two openings here for some airflow which will be fitted will aluminium grills once back from paint."

Marc have you considered small NACA ducts on the sides of the fuse directly in front of the inlet ducts for cooling air for both the bats and esc?
