ORIGINAL: pe reivers
In the pictures is just visible the air extraction ring between cowl and fuselage.
Can you post a picture how you prevent the air from going around your jackets?
I do not know how I must do that Pe, I hope that the baffles I made be enough to do there work in the cowl, but maybe I closed the gap in the cowl underneath the engine with a piece of ABS to the underside of the "jackets".

Cesar.
