Nope. MS-II. Version 3 board.

"The picture below shows a very favorable location for the radiator.
The plan is
to pick up air out of the wheel wells and dump it out over the elevon
hinge points.
Fifteen feet of 5/8x.028 aluminum tubing to move the water to the back
will cost me
about 5lbs, which will be partially recovered by the elimination of a
coolant reservoir.
Basically, the pipe will be the reservoir -- a long, thin one that
will aid in cooling
if I can duct air to it. An electric water pump placed next to the
radiator is another
opportunity to move weight aft, as well as shedding about ten pounds.
I'm also considering installing the oil cooler behind the firewall at
the right inboard
wing strake. A pickup will provide cabin heat. I find this more
comfortable than a heat
muff or using engine coolant."
Not a bad place to put the rad. The P51 had it back there. I don't
think using
the wheel wells alone will gather enough air. You will probably need a
P51 type scoop.
Nawh! It sucked. Old data, and I'm to lazy to update the website. For
that location, there's not enough room to duct air in and then get it
expanded and slowed. The volume is better spent on luggage space.
Try these instead:

The oil cooler is on the other side:

Ducting to get hot air through the fuselage structure:
