I have a Subaru set up made by Dan Woodward at Knight Hawke who recently made Dave Mullins corvair conversion. Dan W has been making Subaru conversions for rotorcraft and airboats for years and is well known in that circle. He also machines the parts for most of the other Subaru converters. Dan makes a large quantity of parts at a time to keep his setup time and costs down. It appears to me that Dan used his "off the shelf" Subaru hub parts to assemble the corvair with minor modification as Dave Mullins Corvair set up looks just like my Subaru.

I said they were "mine" in the sense that I paid for them. Not that I designed them or even made them. I never claimed to know more than William or anybody about the corvair. I offered to be a go between Dan Woodward and the KRNet people because Dan does not have internet access. Anyone that asked I gave them Dan's Info to call or they could email me with a message. Yes William, Dan looked over your drawings but said he would have to do something different. So the only similarity to William's hub is the corvair and SAE-1 bolt patterns. Which William has no claim to. I am not marketing these hubs hubs as my design or setting up a business. I am just informing others of another source for parts. And yes I did answer Williams email tonight as it just was posted today at 1:00am when I got home from work.

From: "Henning Mortensen" Date: Tue, 01 Feb 2000 09:49:19 PST X-Message-Number: 2 This composite cracking which you are talking about does indeed happen but not as you are thinking of it. I am a sailplane pilot and we find that after flight in mountain wave where we are submitting the craft to temps from -10 to 30 celcius over the period of a flight, sometimes fine cracks do develop. These cracks are cracks in the gel-count, not the glass structure. The problem is that once these cracks develop the protection of the glass underneath is not complete and if not fixed can lead to problems. I would certainly expect this type of problem to happen pulling an aircraft from a heated hangar out into the frigid cold. If you like the benefit of heat in your hangar then this is a price you pay.

I found a reference to venting spars in "Homebuilts, A Handbook for the First-Time Builder". Author is Frank O'Brien, TAB Book ISBN 0-8306-2375-2. From page 30 it says, "Before these pieces (verticals or intercostals)are epoxied between the capstrips make sure that the vent hole has been drilled in each. These are a necessity to prevent trapped moisture." Also, Tony Bingelis says in "Sportplane Builder" in the section on drilling spars, pp.52-53, "Some people think drain holes are strictly for wood birds. This of course is not so. Water can also be trapped in metal compartments and can lead to corrosion or even result in an unsafe overload or critical c.g. A preventative measure you can take is to drill a 1/4" hole in the lowest portion of all compartments and sections that do not have natural drainage. These holes, in addition to providing drainage, will allow temperatures and pressurization changes to equalize throughout the structure. When locating drain holes, and before drilling them, visualize in your mind how water would drain when the aircraft is at rest in its normal three-point attitude." Tony B. has more to say about how wind blown water finds its way into places you won't expect, and that 5/16" or 3/8" holes are good for wood too. These holes will help prevent deterioration that comes with time. We all know Tony B's qualifications. Mr. O'Brien is retired USAF with 4700hrs in military aircraft, including 163 jet missions in Vietnam. He wrote his book after building a WAR replica Corsair. I hope this helps.

I just got a 2 gallon free sample of Dow Corning Silastic E RTV Silicone rubber and its catalyst and I'm dying to mold some rubber parts. Durometer hardness: Shore A - 33, Service temperature range is -55C to 200C If anyone has anything small that they would like molded let me know.

Hi Don,
 
My name is Jennifer Evans.  My father, Wes Evans built and flew a KR-2 back in the early 80's (Picture attached).  I came across your site on the internet and was wondering if you may be able to direct me in finding a small model of a KR-2.
 
Thanks!
 
Jennifer

I saw one at the Georgetown, TX (GTU) airport a few weeks ago, N808BS. What a nice bird! Didn't get to talk to the owner though, which is a shame since I really wanted to try on the airplane to see if my lanky 6'2" frame would fit before I plunk down the $$ for plans. Any advice from current KR-2 or KR-2S flyers? Better yet, are there any central Texas KR-2 owners that would be willing to let me sit in their pride and joy? I've yet to find an airplane I don't like when it comes to flying it, so a trip around the patch isn't necessary (though it would be nice). My biggest concern is just fitting in it. Me and C-150's have a problem with leg room.... ---------------------------------------------------------------------- Subject: Re: Drilling Wing Spars From: Knitehwk@aol.com Date: Tue, 1 Feb 2000 23:57:19 EST X-Message-Number: 9 does anyone in the kr community know if a web page and or type list such as this exists for the war aircraft replicas just curious after Ken Jorden mentioned this little tid bit in his recent email to the kr-net thanks Glenn ---------------------------------------------------------------------- Subject: Re: KR-2 From: Knitehwk@aol.com Date: Wed, 2 Feb 2000 00:08:29 EST X-Message-Number: 10 Dear Jenny if your father still has the prints to the plans there is very good drawings and enough information that a small wood model of the aircraft can be built in minmal time using balsa silk and dope.
