 Posted: Sun May 04, 2008 8:27 am Post subject: Overhead console head room |
 |
|
Before installing my cabin top, I am trying to decide if I need an overhead console, and what the impact on my headroom will be. I am only considering the console for the front seat gaspers, as lights can be installed without one. I am 6' 4'', and am concerned about the loss of headroom from a console. I sat in a friends 10 that had a full width console, and had a headroom issue. If I only brought a duct forward to route air, could that 3inch wide, or so, duct up the middle of the cabin top cause a headroom issue as well? I don't like my headset bumping on anything! A real pet peeve. Has anyone ducted air up from the front, possibly from substituting the steel cabin support bar with a larger diameter, thinner wall tube, and running the air thru that? How about enclosing the existing support with a fiberglass duct? Maybe mount the mag compass in there and really look custom.
The real question is, do you truly need the additional air? My RV8 has only the panel mounted air vent, and it is more than adequate, once airborne, and I fly out of Las Vegas. Of course on the 8, you slide the canopy back for taxi airflow, an option that isn't available in the 10. How about taxing with the doors slightly open? Are the doors too fragile for that option? My friend with the console says that the gaspers leak air , and that's a nuisance in the winter, but he feels the overhead gaspers will be a blessing in the summer, but as yet unknown. Would an inline fan, when turned off, restrict the ram pressure enough to prevent unwanted leakage? A shutoff valve would work, but that's complexity and weight that gains you little.
Opinions or experiences anyone?

Chris,
I know we talked about AirCrafters' console on the phone, so please don't take this as a sales pitch;-)
The stock ducts below the panel let in a lot of air. You can aim then where ever you need it most, from a whisper to gale force.
I'm tall too, that's why I didn't want much hanging down from the ceiling. So far our console is working out nicely.
I taxi with the door cracked open but with all the fuss lately I may stop that. I've never had a problem, even with it full open. Usually I just leave it cracked and hold the bottom edge with my left hand. I'd hate for it to depart though, so I'm thinking I'll just quit that.
OIur RV is in the interior shop now. Should be done in a few days. I'll post some pictures then.
