Many years ago, I had to opportunity to have a great long conversation with Jim Eich, a most interesting man indeed. Jim had stopped selling his JE-2 plans as he knew there was a problem. Basically it was the yaw control which Doug mentions, it was possible to go into a "P" factor flat spin during full power climb out and you could not recover from it once it started. I think Jim told me that 3 machines had done this including his, everyone walked away without major injuries. If you look closely at the tractor Arliss made and the one Jim made you will see very significant differences in the vertical and horizontal stabs. Jim said he now knew his vertical was to small and was "shadowed" by the fuselage making it even less effective, he said it needed twin verticals out in the slip stream and prop stream.
Other than the yaw problem, it did amazing performance as a 2 place open cockpit on the hp he used (seems like it may have been aroung 90 hp, not sure) he said he felt that the main gear should be improved also.
Jim was a great guy, if you would take the time to talk to him, he would take the time to talk to you, just another one of the benefits of going to the conventions and going nose to nose with the best, also got to have a nice long conversation with "Mr. Carter Sr." at one of the conventions, it just doesn't get any better than this, and all of this for a membership fee !!!!
