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?

  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!
