Guys sorry I should have posted pix of the actual duckting.
Yes it has full ducting from the intakes , arrounnd the engine and all the way to the exit. I tried to make this a smooth as I could.
It is the same tipe ducting as described that is made up of 3 sections and then assembled into place.

Tday I will make up 2 more thrust tubes from plastic just to test the difference. One with a 10mm larger and one with a 10mm smaller diameter than the one I have now.

How do you guys measure the actual thrust of a jet? I dont kow how acurate a digital scale would be if it stands up vertical.
I was thinking of maybe cutting a cheater hole into the centre section rear of the intake ( the rounded piece) , it should allow more air into the fan through the nose gear hole BUT i am not sure how this turbulant air will affect the fan. If there is enough space I could make a seperate little scoop that feeds into this centre section.
Could it be that the BVM needs more air than the 100% FSA the intakes provide, if the plane is moving forward, would it not ram more (smoother) air into the intakes?
