Subject: [FlyRotary] EWP series flight
data & hail
I got up for awhile today and able to get a little more info. With engine
running and cooling system pressurized I found that with a single pump running
in the series configuration flow was only ~15% reduced from previous flows
without the spare pump. However use of both pumps increased flow by ~30% over
a single pump. In an extended climb I found that temps began to climb faster
than previous, but turning on the second pump reduced the
temps.

Then I looked through the air
inlets and found that my rads looked like I took a ball peen hammer to them.
All of the cooling fins are pounded in. However the oil cooler is fine with no
dents at all. I'm certain that the coolers can be salvaged with a few hours
and a pair of needle nose pliers, however I'm not certain if they will ever be
as efficient again. I will attempt to straighten them but am prepared to weld
up a new set if necessary.
At least I finally got to fly again today and gained some valuable experience
as well.

Todd, glad to heard only minimal damage to
your craft. There is a wide blade pliers -ike device that is designed to
straighten radiator fins. It works much better than needle nose
pliers. You might be able to find it through one of the auto
catalogs.
