Hi! Peter/Christine #110
IMHO !!!! Watch out for an icy draught on your knees ! (rheumatism and
all such things). If you have the NACA Ducts supplied from Europa they need
to be horizontal or they aren't efficient, I am advised , which means you
must resist the temptation to aim them upwards . Also best to position them
only just under the front of the panel, pilots side at least to facilitate
reaching easily . I'm building a 'trike' with a handbrake valve block just
aft of the NACA VENT which was a struggle to get the pair to 'co-habit' !
Also I would consider it very important not to 'invade' either the
super/bottom join line of the fuselage or the firewall 'joggle'.Better make
sure that the NACA surround is dead flush with the outside skin otherwise
it is a sod to fill on four sides at once.!

Subject: cabin ventilation - locations
Now that I'm ready to cut the fresh air vents for the cockpit I've been
studying the photos in the club newsletter and anywhere else I could find
them to determine where builders have been placing them. It seems we all
have different ideas. Before I make my final decision I would appreciate
some feed back as to benefits of the 'high' as compared to the 'low'
positions or vice versa.
My thinking was 'high' as this puts fresh air closer to the face and feet
can stay warmer, but the alternate location nearer the footwell may be
better for some reasons I haven't thought off.
