The Tzukit / Fouga was a mid wing design powered by two tiny Marbore II engines of less than 1,000 lbs thrust each . The Marbore engine was the basis of a license version to the USA manufacturer Teledyne J69 engine which powered the Cessna T-37 Tweety bird trainer among others

The actual engines were mounted in a side cheek nacelle behind the wing root with the air inlet extending in front of the wing via an air tube that went thru the wing spar within the nacelle.
Here is the inlet
the inner lining is inserted from behind using a wood stick with a drop of glue to keep it in place.
continue the nacelle going aft
Notice, I will build landing gear bays into the wings. However, The current spar design interferes with the cutout and I have to figure out how to build the wings and support them. For now, I used temporary wood sticks for the spars
engine exhaust
personal note:
There are no shaping formers in the nacelles and I thought that the shape may not be good. However, I was surprised that even with no internal structure the simplicity and ease of build kept its proper shape.
