Thank you all! I am very happy about your comments

Btw,
Torbjörn, thanks about those comments about the propeller. I forgot to mention that it is actually carved from some 1/48 spare ww2 propeller. I firstly thought of using some Roden spare as basis, but the were not long enough (they are from Albatros and Fokker fighter kits). I cut two blades out of a 4-bladed propeller and cut and sanded them into shape. Then I glued them to the spinner. After some filing and filling, I painted them with acrylic paints. C.V had exeptionally big propeller for a two seater, because of the reduction gear the 8-cylinder engine had… so a lot of air moving with relatively low rpm.
Now to come to think of it, i just realised that Roden Gotha kits would have had big spare propellers!
Cheers, Skyhook
