I decided to draw a template for a EC-135 and a H-145. I plan to make quite a few different air ambulance services but I decided to just start with NPAS and MAA.
NPAS:
NPAS EC-135:
NPAS H-145
Midlands Air Ambulance:
Midlands Air Ambulance EC-135:
Midlands Air Ambulance H-145:
I also plan to make similar templates for a AW139/365, S-92 and a Bell 429. That will allow me to make the HM Coastguard fleet.
