I was not sure how it would work, but this is experimental right? I have an early Jabiru 3300 S/N 16 and the oil cooler I got with the engine is not what is provided now. It is 2" thick by 4" x 6". I fabricated a housing to fit around the oil cooler and put a cable operated door at the bottom to dump the heat into the cowling in the summer months. I ran two 2" SCAT tubes from the oil cooler housing to the fire wall. I have the oil cooler housing hanging from the left side of the engine mount, half way between the engine and fire wall. There is a 4" SCAT tube that supplies fresh air to the oil cooler, so no engine compartment air is passed into the cabin. I flown with OAT below 30 degrees, and the heat will just about drive you out of the cockpit. At 40 degrees, I have to have the fresh air vents open almost full to keep a comfortable balance. I flew a Commanche before building my 610HDS, and we had to weld the muffler and heat exchanger at every annual. I did not want to have to risk carbon monoxide on my 601. I am very pleased with the oil cooler heater. I block off the SCAT tubes into the cabin in the summer. I still need to fabricate a panel mounted shut off for convenience, but have been having too much fun flying. Maybe this year???

Beautiful bird, the "Casual Passion"! I'm building an HD, from scratch, and would like to ask you a couple of questions: 1) Is your canopy hinged like the RVs', i.e., in the middle as opposed to the sides (Heintz's design)? 2) I intend to have my 601 unpainted, just polished. Thus, a metal cowling would be desirable. Did you make or buy the nose bowl (if so, what kind)?

Corbalis" Subject: Zenith-List: oil coolers --> Zenith-List message posted by: "Leo J. Corbalis" I don't think you will be happy with an oil cooler in the cockpit. Putting some kind of split flow scheme in the oil system is technically complex and something else to go wrong. Its one thing to run a capillary tube to an oil pressure gage and having full flow of oil in the cockpit. You might be able to fold a capillary tube back on itself to stop an oil leak and a totally differient emergency blocking a 1/2 in. oil pipe. Parts to split water flow are readily available and well proven on cars. Try using the oil cooler exhaust air to warm the cockpit. I have my exhaust muff intake behind the oil cooler on my Rotax 912 and on a cold day I can fry my legs with it full open.

This is how It all started for me ! . About 6months ago I sent an email to ZAC on this subject and got there response which has been covered very well in answers to questions on the list, MAKE DAM SURE you leave enough length on full aileron deflection so that it will not jam your ailerons!!!!. I have a 601 HDS and during my last flight of 4250nm round trip mostly in rain storms that the water flow over the wings would stop @ the aileron hinges and go down through them . This made me think of what lift I was loosing on the HDS wing, and also posed the question of WHY the negative pressure under the wing / ailerons?It should be positive if the critical Aof Attack is not exceeded . Not being an aircraft engineer, one must think it out in layman's terms. Look @ the gap between aileron and trailing edge of the wing and just think about what the airflow is going to do in flight. Seems to me that there is a vortex being produced @ that gap , changing the airflow and sucking the air through the hinges. For the people who have hingless ailerons all you have to think about is the DRAG produced,IF any, but like me I have to think about the drag and the loss of lift. I will be doing some experiments soon on this by first using tape under the hinges and then the gap seal. Which some on the list have mentioned / RE the extension of the bottom skin / or de riveting and installing a piece of aluminium with a rub contact on the aileron to save the paint work , BUT this piece MUST BE LONG ENOUGH so not to catch and spoil your day. Cheers and safe flying Norm Turner, 601 HDS Rotax 912 / 295Hrs. ________________________________ Message 10 ____________________________________ Time: 07:16:43 PM PST US From: Michel Therrien Subject: Zenith-List: Safety wiring AN165 turnbuckle end --> Zenith-List message posted by: Michel Therrien Hi Group, I'm trying to figure out the right way to safety wire a turnbuckle with an AN165 "pin" end. For cable end, it's simple (well, at least, documented), you run the safety wire through the hole. And for a "fork" end, you run the wire in the slot. But what do we do for the pin (or bolt) end?

Then you would only have to safety one end. To what are you attaching the pin end? If the pinned end is possible to rotate, then you should use a clip locking turnbuckle. I have seen a pin end fitted to a chain. Then the safety wire is run thru the chain link.
