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.

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!

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.

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.

From: "Don Honabach" --> Zenith-List message posted by: "Don Honabach" 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.

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.

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. ________________________________ Message 13 ____________________________________ Time: 08:59:37 PM PST US From: "George Swinford" Subject: Zenith-List: Crazy rad idea --> Zenith-List message posted by: "George Swinford" 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. George
