Since I was not fully happy with closing up the wheel bay, I did another try. Looks a bit smoother now to my own opinion.
Together with the kit, Erik @airbum, provided four engine replacements. Much more detailed as the original ones and having two rows of cylinders. After glueing them together with CA, I gave them a black wash.
All four finished do look like this.
The canopy fits excellent. connection to the fuselage is very smooth.
