The distance between the inlet and exhaust is fixed so it all comes down to which suffers the most from the lack of space. The inlet area is above the FSA whereas the exhaust divides & tapers down to 90%. My experience suggested it was more important to maintain a good exhaust path than the inlet given the inlet velocity will be only about 80% of the exhaust.
Surely 350g thrust down from 500g is a reduction of 30% not 50!
I am building the plane to take into account the limited thrust. It should still fly adequately on a 70% thrust to weight ratio particularly given its generous area & un swept wing. It won't be a 'rocket ship' but then neither was the full size.
We shall see.
