Throttle body inlet on right.  Bent radiator.  Exhaust and belly board.
Radiator partially welded together.
I think it could fit here pretty well.
That's my youngest daughter, Anna.

She is very cute :)

OK I think we can get this to work. Plumb the rads in parallel
if possible. What are the dimensions for the rads?



Paul Lamar



Rads are 8.5 x 13 x 1.5 each.  Welded joint is a common tank.  Plumbing in
one end, through first core, the joint tank and into the next core.  Might
be possible to come into central tank, then flow outward to end tanks, and
rejoin plumbing back into the pump, but that is quite a bit more
complicated.  Hoping to treat it as one big, but bent, radiator.

I like the drawing.  How much depth would be needed for wedge opening?

Lewis


   Here is a more accurate dwg based on the actual size of the cores.
   They are a bit on the marginal size so you are going to need a very
   effective cowl flap. Don't worry about the drag as take off and
   climb out happens at a speed were induced drag is high and you
   won't notice any climb deterioration with the cooling cowl flap open
   or closed. You will notice a strong cooling effect however.
   As long as you don't have an open hole pumping air into the
   cowl. The idea is to raise the pressure across the cores as high as
   possible.

   Start with 3 inches. You can always block some of it off if
   you don't need it.

It's possible I could mount the rads in a more vertical position, say near
   45 degrees to line of flight.  Any advantage there?

That would give you a bit of room for an oil cooler.
Not stock RX7. I think that may be a bit too long at 24 inches.
Something more square.

Its weird I've just been looking over the various Rutan designs this past week, I like
the Quickie/Q2 but had dismissed it due to believing a rotary wouldn't fit...now this
comes along, BINGO! Nice work so far sir, LOVE it!

Thanks, but it has been a royal pain.
This is my seventh airplane.  Probably my last, unless there is a design of my own out
there...

The Q2 is a beautiful airplane, and I think, we'll enough designed aerodynamically, but
has very cheap, somewhat dangerous, and stupid systems internally.  I disposed of most of
the kit parts that simply were not up to a reasonable safety standard.

There are many Q2's out there fore sale with less than 50 hours on them.  That's about
how long they are designed to last.

See the website Quickheads.org for a detailed breakdown of important safety mods to the
design.

The engine has been, by far, the most interesting part of the project.  It still has a
way to go.  At least it is possible to get a good look at engine operation before risking
a flight.  I plan to tie it down in the driveway and keep running the engine until things
quit falling off, exploding, or overheating.  At that point, it's off to the airport!
