I am sure however if the radiator fails in a w/c aircraft

engine you are going to have an engine failure. The oil cooler won't
do it alone. Even though the rotary uses the oil for 30 percent of

its'

cooling. The rotary isn't the only case where this is true. A

failure of

the water radiator wouldn't necessarily fail the oil system either.
No cooling of course. Perhaps the best compromise is the layout
you did for a long ez was it? Where the builder had the Water
radiator and the Oil radiator paired in the lower inlet scoop. This
location allows a louver system to work on both rads as well.

I think the second independent cooling system buys you a little more
time to get it on the ground >

 My recent experience with water pump failure showed that the RV6A could

be

kept flying without the water pump.

How long did you fly at what power level Ian?

When the pump pulley failed the temps increased rapidly. I then descended
from 10000' to 7000' with the thottle closed, this brought the temps back to
normal and I found could limp along at about 70knots in level flight. This
was not a scientific test as I had other things on my mind!! It was a case
of  'that's nice to know, now lets get her on the ground in one piece'

Good work pushing over and cooling off the engine. Altitude is your friend.
So brain was in overload and time stood still? In other words you
have no idea how long you flew like that. :)
