There are pictures some of my 3D "STL" models of warbirds details. Now I´m working on Spitfire parts.

For Mustang and Spitfire pilots I make scale resin exhaust stacks. Merlin "Fishtail" are 1/5 and 1/4 scale. Merlin Round stubs are 1/4.6 and 1/5 scale.
The bigger Merlin round sets are available with fibreglass shourds. The shourds work with TF giant Mustangs, Ziroli´s, Carf and many similar Mustangs.

There are first JP Warbirds 3D printed radio block and batteries for 1/5 scale P-51.
