Designed to kill, converted to save.
Cal Fire North American Rockwell OV-10A Bronco

The California Fire Department uses quite a few Broncos as spotter and lead planes to detect fires and guide the water bombers to the spot. So my Bronco will be one of them.
Cal Fire operates OV-10A and D and did some modifications to them. Some have 3-blade props, some 4, some 5-blade ones. Antenna configuration seems to be very variable too. The main modification for the kit will be the omission of the weapon sponsoons.
I will go for an earlier version of an OV-10A with a 3-blade prop.
