I have worked on it a bit, trying to improve prop blanking due to fuselage... I have therefore squeezed the rear section of the fuse leading to the engine mount.
I also took the idea brought by excellent Steve Elsey (author of the awesome Crusader II design), and tried to fit it into my design... The basic idea is to hide the engine behind a hollow cowling hiding the engine under most viewpoints. I can mount the engine upwards in this configuration as the engine is not very visible
. Steve Elsey still mounted his engine rotated 90 deg with a tuned pipe under the belly [8D]. I have to think about it [:-].
