DC-3 Cowl Flaps ?
Does anyone know why some DC-3s/C-47s don't have, or have fixed cowl flaps ? All the DC3s here in NZ (pratt powered) that I know of don't have them, yet in the in the flight manual it talks about them (part of the hydraulic system) and all the ones I've seen in other countries and in all photos seem to have them.
Must be a mod yet I've no info on this. Anyone know the details, reason why etc ??
Cheers.
