I've looked at this one too. Couldn't find out much about it though. It's neat that HCI isn't the only company making modern radials though. Jim -- In...
Hi, You might look through the Sport Aviation indecies of old issues. I remember seeing some words about these engines there some years ago. Earl ... ...
I'm interested from the standpoint of it's design and nothing else (I don't want to build it or to buy a copy). I have not seen a radial design that is, what I...
I hate to get on here and complain, but... It was called to my attention that a guy is copying an old, non updated set of R-180 plans and selling them on EBay....

I agree with you that it is a terrible thing the seller on ebay is doing. However, my thoughts run to believing that if he isn't at least reminded of U. S. ...
A note to you all. My husband is on this group. I also have a copywritten article, which I sell on Ebay. Ebay's rules are simple. You notify them (with...
Thanks all. I fully intend to do what I can to stop the seller. First I have to get Ebay to tell me who he is, which I am working on. The copy right emblem is...
Andy Get on their case. I know enough about your engine, that there is a lot of uncompensated effort involved. Tell your dad, I am getting close. Looks like a...
I'm glad that everyone feels this strongly about Jack's hard work. So far everyone has declined any requests for plans details. A few messages back there was a...
I have the item # for a bid I have working on for the plans for the 5 cylinder HCI and I'm getting worried about the possible it's a copy not original. If your...

This is a friendly word of caution to those of you that have purchased plans for the 7 cylinder radial from HCI. Do NOT make any of the parts until you talk to...
Folks, I and many others are looking for an engine that can be used on WWI replicas. Now, the radial works fine for many of them, but the birds I am...
I'm using 4340N for my mainshaft and 4130A bar stock for my cheek plates. The mainshaft has been threaded and ground and is ready to go to the local heat treat...
I've talked to Ron and Andy about this issue. Ron has a bonafide complaint and if any builder has any help or suggestions for him please feel free to help him....
Seems like it would work... At least for a while. The corvair crank doesn't have counterweights so your bob weights on the unused journals would need to be...
Brad & Jim, I just picked up a 110hp Corvair engine a week ago. Brad, if you need any measurements on the engine, I would be glad to gather up the data....
Hi Jim, Check out http://groups.yahoo.com/group/quorn_owners/ for some information on grinding threads etc at home. You will have to join first but the files...
Beware the 3 cylinder inline. Without an awful lot of Torsional Vibration Analysis work it tends to shake appart everything it is attached to in service. Some...
... Brad, Have you seen this picture of this half-convair? http://www.mykitplane.com/Planes/PeoplesPlanes/halfcorvair.jpg Looks like someone years ago had the...
Hmmm... I actually thought about that, but I don't think the Geo has the needed spacing for air cooled cylinders- even the little corvair ones. Then you have...
Thanks Greg, It's funny you should mention thread grinding after heat treat. A couple of days later I found reference to it in Machinerys Handbook. Apparently...
Hi Rick, The person to ask is Jack on that one. There aren't that many although in the next few years this should change. One fellow has a turn-key engine...
Here is some extracted data from communications to Sadler: "Sadler and the Gewalds began a worldwide search for an existing reliable four-stroke engine and...
Thanks for that bit of information. I have performed some research on this design and the crankshaft has 2 crankpins 180 deg apart (out-of-phase). This would...
