KR> Landing Helper Idea
This is a basic idea to give you the distance from touching down and if you dipping a wing. http://www.backupsensorshop.com/Car_Backup_SD2.asp This is a basic backup alarm with the ability to measure distance. On your final leg you would turn it on and get a visual distance and audible tone all the way to landing. This would be simply to do, just hook the wire that goes to reverse wire to a power switch and turn it on. Since we flare to land (depending if your a taildragger) you can mount the sensors at a countered flare angle or put them on a ball mount so they always hang down regardless of the plans angle. I think this would be helpful for the landing gear slammers and the occasional miss judge landings. If the sensors are wing mounted then you can see if you dipping a wing upon landing. I hope this is helpful for us new guys. Thanks, David Boyer
KR> Simply Folding Wing
I have been talking with badbob0007 (Bob Johnson) and we both would like the ability to fold our wings up and directly over the top of the canopy for transport. This is a basic idea on a double pivot design so the wing can have enough clearance to fold. http://i1081.photobucket.com/albums/j354/davidpob/wing.jpg I hope this will be useful. Thanks David Boyer
KR> Zenith Carbs and source reference
Ok, we all know what Cam, crank and setup to use for our corvairs. Mark Langford and William Wynne have gone through a lot of trouble doing the R for us and I wish to thank them. However when it comes to carburetors for the corvair there is some questions that need answered. The certified carbs are very expensive and hard to find while Harley CVO carbs and Zenith carbs are available and reasonable. So I'm looking hard at the Zenith Carb and what the numbers really mean. On forums the Zenith 1821 carb is being called a number 68 and 267 Here is a chart to show you the size engines for these carbs. Just click on the updraft carb 68 or 267 to see the specs. http://www.leklein.com/Zenith-Fuel/index.htm Now here is a chart to see how these carburetor numbers are related: http://www.lotus-equip.com/Zenith%20Parts%20Reference.htm The numbers you are after is 13922, 14992, 14995 and 14998 depending on your engine setup and size. These updraft carbs are dirt simple and can be adjusted easily to run your corvair. If you live in the woods like I do then here is the cross reference chart to get a carb from a tractor dealer: http://www.lotus-equip.com/zenith.htm Now here is a dealer like www.greatplains.com <http://www.greatplains.com/> that carries Zenith carbs for aircraft: http://www.hummelengines.com/pricelist.pdf And a small article on carbs that contains good information: http://users.lmi.net/~ryoung/Sonerai/Carbs.html http://clubs.hemmings.com/clubsites/DurANT/Tech/Zenith-updated.PDF These updraft carburetors don't like ram air or high pressure and need to be setup with available carb heat for flight safety. Here is the cheapest I found them: http://clubs.hemmings.com/clubsites/DurANT/Tech/Zenith-updated.PDF I hope this helps out in trying to find a carburetor for your project. David Boyer
KR> Great Landing Gear
This idea is from Norman Michaud who had this setup on his Kr2s. I'm posting the info for builders who need land gear. The leaf spring from 1985 Chevy astro or GMC Safari are fiberglass and make great landing gear. They are light, cheap and available almost anywhere. Each spring is 60" long and tapers to the middle and will male a set of landing gear per spring. So a set of springs is around $60.00 and makes two sets of gear. They mount on the spar like normal Diehl gear and much cheaper. This setup is what i'm doing with my large plastic easter eggs i'm using for wheel pant molds.David Boyer
