I put a slot in the middle to allow some air to make in. It was to much blockage. The turbine was sucking the doors up and canopy under full throttle (I posted a youtube showing that). It was hauling the mail and didn't slow flight as well as I would like. I open up the slot and added some more holes to get to a happy spot with speed and landing.

I have seen some of the guys building a adjustable plate at the back in of the intakes. I read somewhere when they did that I would sometimes split open. It is very thin there.

If I had to guess it was about 60% restricted.

I don't have the pictures with me but look back in the thread my post 566. I used epoxy board from Dreamworks to cut them out from and epoxy them in.
