Interesting project!
can you compare resin part with my drawings please?
radiator, stab; elevator and rudder
View attachment 247123
thank you so much I saved your images to watch later.
With a length of 32mm radiator CR is really too short.
The length of the actual radiator measuring 1307mm (40.8)
width 668mm entry (21mm) and 748 output (23.4)
the wider, 872mm (27.2)
All is fine but you have fogotten that the rudder image is taken with a some angle contrary to the radiator for instance. It my have caused looking longer in chord optically.
