Didn't George Graham already do that?  His rad is fed by
NACA duct.  No cooling problems after he unblocked the
heater hose inlet. EZs fly at a

1

or 2 degree nose up attitude.

Joe, "after he unblocked heater hose inlet"?

..whats that all

about? ...Chrissi

Chrissi,
I believe I remember reading on George's site that he

experienced

an improvement in coolong after reconnecting the aft

heater outlet

which he had originally blocked off. Dean

     To all concerned,
        This might be a thread to concern us all. It is well known
that the  rear rotor housing (front in tractor A/C,rear in pusher)
runs at a higher temp  than front housing because coolent

cools front first then flows to rear housing.

        Opening the heater outlet on the rear housing and sending
coolent back  to pump inlet will increase flow through rear

housing.

Most 13B's fail at the  rear rotor probably because it runs

at higher

temp IMHO.

I plumbed mine to return to the water pump after running with it capped
for 100 hours and after reading of George's improvement. I saw no
difference in the overall coolant temps. I cannot monitor the rotor
temps individually so maybe their temps are closer balanced now but I
saw no overall change.
