Ernest,

First are you using space left and right of the rear seat for baggage ?? My baggage will

be behind rear seat as my fuel tanks are saddle, left and right of longerons behind main

spar carry- through (26 gal each)..........Inlet lip will not protrude enough to use as step

if I follow NACA report 743 (subject to change if I need to modify lip from 743 shapes).

Pitot will be top of vertical (best place in my opinion).......You are right in that the outlet

duct will need to be curved to the outside of my fuel tanks and exit above retracted gear..

I plan on gear doors (ala Bernie S.) to eliminate gear well turbulence......You are right

in the outlet duct being somewhat convoluted !!
