I know very little about free air cooling as it relates with aircraft engines but I will try to explain how I think it works. As a refrigeration mechanic my understanding of the concept in downflow cooling - we call it reverse flow cooling in my trade - is that the cold air coming into the air scoop will first make contact with the warmer section of the engine's cylinders, that is the top horizintal sections ( since heat or hot air rises). Then as the partially warmed up air keeps going down it makes contact with the cooler portion of the cylinders, that is the bottom horizontal portion. In this arrangement maximum heat exchange takes place as the coldest air flow contacts the warmest section of the cylinders first resulting in maximum heat transfer. In upflow cooling, the cold air coming in the air scoop makes contact with the cooler bottom portion of the engine's cylinders picking up heat and then flows to the top portion. Because the air has already picked up some heat before it makes contact with the warmer top portion of the cylinders the heat transfer that takes place at the warmest location is less. Hence downflow cooling is preferable when maximum heat exchange is desired. I hope this helps and if my understanding of the concept as it relates to aircraft engines is wrong, I would hope to hear from anyone who reads this post. Thanks. Bruno Caron

Thanks for your input Jon,it is good to know that there are other people interested in manufacturing these parts. I will get in touch with the Cozy Girrrl and also Dale R. Bruno Caron

Since Ken Brock Manufacturing is no longer in business, are parts (hardware) available form someone else for building a Varieze. I have checked on the Aircrfat Spruce website, they have a few parts but the selection is very limited. Thanks. Bruno

Hello Group, I have posted on this site a couple of times before but for the most part I have just been in the background for the past year or so. Circumstances in my life - strike then loss of job- prevented me from making a commitment to build. Things are looking better now, I belive that the Lord's providence has opened a door for me and I have just been hired by the school district in my hometown. I start this coming Wenesday, March1,06. My name is Bruno Caron I am 49 years old and I reside in Kimberley British Columbia Canada and my occupation is HVAC/R mechanic. Last week I purchsased on E-Bay an original, unused set of VariEze plans. I finaly decided that it was time to stop dreaming about building and owning a plane and to do something about it. I am not a pilot but I have a lot of hours in airplanes and as far as I can remember I always wanted to fly. I am hoping to start pilot training sometimes this spring.... I have no experience with the fabrication of composite materials. In order to change that I looked around in my area for a palce where I could get some hands on training. I have made arrangement to go to Vancouver, for a month, at the British Columbia Institute of Technology to train with their ongoing AME-S class in " Aircarft Structures Composite Fabrication and Repair module. The course runs from March 27,06 to April 21, 06. I thought that this would give me a good start. I have also purchased the Rutan video and book on composite construction. Very intersting. I must mention here that I was very pleased last week when I found out that my new boss would allow me to take a month off without pay to attend this course. I talked to him two days after I was told by human resources that I had the job and he was quite agreable to let me go. So I will go to work for the next 3.5 weeks and then unto Vancouver which is a ten hour drive from home. But I guess that is enough for now about me I do not want to write a book here today. I would like to end buy expressing my gratitude for all the builders and the builders want to be- like me- who have posted on this group over the years as well as those that have their own websites. Thank you for your time and effort to pass on your knowledge to people like me. It is because you where willing to take the time and share your experiences that I am taking steps today to build an airplane. Thank you also to Jon for keeping this site going. One last statement before I sign off... I think that Canard airplanes are the nicest looking aircrafts around. Bruno Caron

Check out this website about rotary engine. The 814 twin pack, a 160hp.engine.... twin engine safety..... Sare your thoughts. www.rotaryengines.ca Bruno Caron

Hello Mark, interesting post thanks. While browsing I have come across a site that may be of interst to potential Jabiru engine owner's as well as others. It is an elctric heat de-icing system for carbs. Check out this web site. www.jabiru.co.uk/IceEliminator.htm Bruno

Hi Len, thank you for your reply, I know that Jabiru has been developing firewall forward packages for various types of aircraft and they advertise on their web site that there are more to come in the future. Perhaps if there is a demand for it they possibly could offer Cozy packages. Anyway this engine got my attention for a number of reasons and I wanted to find out if it had been accepted by Canard builders. Thanks again Len. Bruno

Hello everyone, I have been reading about Cozy for a good while now - better part of a year - If i may I woul like to ask a question??? Give me your thoughts on this possibility;a Cozy MKIV equipped with a Jabiru 5100, 180 Hp. engine... has anyone gone that route before. I would appreciate your insights. Thanks Bruno Caron British Columbia Canada
