Actually because my prop turns counterclockwise (viewed from the cockpit), I
expected to need a touch of left rudder during takeoff and climb -- but in
fact very little is needed. IF anything, a touch of right rudder is needed
in descent to offset the reverse effect! ;-)

I have a Co-Pilot digital LCD compass for my car. It's built for use in
automobiles. When it gets hot in the car, wether using the windshield sun cover
or not, the LCD has a few light shades of rainbow colors & I am able to see all
the segments on the display when I turn it on, making it useless. I'm guessing
it has a low quality LCD & I'm sure other components in it but I hope the
aviation type are better. It does get pretty hot in those cabins in the summer.

Why don't we just run cooling pipes in a straight line? Maybe up and down
the strut or something?
Conventional rads need to fit in a compact space in any other vehicular
application, but we have lots of space to string them around...

I see what you're saying. I guess any screen with an LCD will have these
same problems in reflective sunlight. Maybe the best solution is to stick
with those ol mechanical gages.

Congratulations on your first flight with 601 XL C-FDSY!!! It's a
tremendous accomplishment to begin logging hours on your airframe

Congratulations, DAVE!!!
Well done. There's one comment you made that caught my attention:
>May have to add a touck of weight in the tail/battery area.
>Full aft trim required to fly straight and level,hands off.
Did you have full elevator authority through the full speed range? Are the
weight and balance computations in the proper limits? Was the aircraft was
in the proper envelope for flight (i.e. properly loaded)? Could the problem
be with the trim system itself rather than the C of G of the aircraft?
I guess all I'm asking is 'do the CofG numbers confirm that your center of
gravity is too far forward?' before you add more weight.
Again - Congratulations! Enjoy you new bird!

Apparently someone in Quebec installed a radiator in the fuselage behind the
seat, and addded automotive fans to the sideskin/inlet to ensure airflow on
the ground. Heavy and overly-complicated....for sure, but innovative at
least.
What you propose is intruiging.... how about an entire upper or lower wing
surface designed to dissipate heat?....
Or a large underbelly section? We have so much more space to work with
compared to a car .... I wonder how much heat a single (long) aluminum pipe
would radiate? What if it was equipped with fins of some sort?
Hmmmmm.... it is true as you suggest. We have locked ourselves in with the
concept of automotive radiators. There may be a lighter, easier design that
would be tailor-made to an aircraft...

That's a good point. One of my friend has a similar
problem, but his Balance calculation says he's within
the envelope.
He decided to re-pitch the stabilizer to resolve the
problem. He will try this in the coming week.

PS: Congratulations Dave! I hope to get my plane in
the air this year as well...

One of the ideas I've been kicking around is why are we mounting the
radiator the long way instead of using one that can be mount on the
short side?
So instead of doing this
ENGINE
|--------|
|--------|
|--------|
|--------|
|--------|
|--------|
|--------|
|--------|
|--------|
Do it like this:
ENGINE
|-------------------|
|-------------------|
|-------------------|
|-------------------|
|-------------------|
My guess is that the front part of the current design doesn't get much
air through it and that the air is forced through the back of the
radiator's fins.
If this is the case you could then get more cooling coverage by reducing
the depth and increasing the part that air if forced though. Ultimately,
the most efficient design would be a long tube with fins that run the
course of the center wing section like this:
|-------------------------------------------------------|
Just thinking out loud.

Keep in mind, that the cooling coil should stay within the range of an
efficient propeller wash, for cooling on the ground. Also the further
away from the engine, the more cooling fluid is needed and therefore
more weight added to the a/c. I think, placing the rad into an
operational convenient place and using ductwork with a venturi on the
discharge side of the coil would be my choice.

I got a call yesterday from my insurance underwriter (AIG). They have
agreed in theory to pay me the full agreed value of my CH601HDS minus my
$100 deductable. I haven't seen any money yet. They have to send me some
paperwork and get that and the logs and then the theory goes that they will
pay the claim. They didn't try to get out of paying or pay less than full
value, or anything like that. On Wednesday it will have been a month since
the accident, so it is almost guaranteed that it will have taken them over a
month to pay the claim.

Grant:
I believe that the Supermarine Schnieder Cup racers (early 1930s) used skin radiators.
A few other specialized airplanes have also. Probably not a very practical
set-up for everyday low maintenance airplanes.
The F-4-U Corsair had air inlets for the oil coolers right in the leading edge
of the wing roots. I don't know where that air was exhausted.
I looked at Frank Hinde's radiator installation today at the Arlington fly-in.
The flow of air into the radiator is obstructed by the two radiator hoses and
the nose strut, as well as by being quite close to the muffler. I find it remarkable
that it cools as well as it does. Moving it aft looks like a good idea
to me.
