  1. I cleaned up some WAF I had off my KR-2 looking for flaws and mainly just to get a good look at the metal and they seem to be fine. I also cut the Mahogany ply to plate the root spars for I can get the spars onto the drill press and get the control stick mounted and WAF along with the front seat mounting brackets. 122228005_waf1.jpg.fdd5881e3b7de4edd3e8840eedcd1e15.jpg

  2. Thank you.Nev I have the data plate it say's O-200-1 and from I can find out it's a 90 hp witch would be good for a KR-2 and I suppose weight is comparable to a Cont. 0-200. I'll try and contact Southern Aero. Thanks again. Don

     

     

  3. 90 hp at 3000 rpm sounds just right to me but like you say the friggen weight is the pain. Maybe a alum head? I want one that is bone stock and a bunch of new and used parts to scrounge from. As far as HP I can only hope to find one that is close to or better then a 1835 VW on take off and that isn't much. I like the Thermo K because it is such a strong little engine and would sound cool in front of my planes. Any good Alum block inline 4 cyl Diesel motors out there?? Next great find will be like the Corvair, slowly we all will use up the left overs and look for some thing new!

     

     

  4. and I came up with a new idea. 4 cyl. diesel Thermo King engine, Max Rpm 2800, prop will love it. I think it can be cut down to 220lb. and then maybe add a turbo. So on a KR-2 you have to add a little Aft C.G. bit longer take off roll, land a little hotter. don't matter whats up front as long as you got the room?

     

     

  5. When I got my KR-2 I thought Corvair was the way to go so I ran off and bought the W. Wynne manual and started building up an engine. Mind you this was before the fancy gold stuff and 5th bearing. Then "wow" crank problems and a whole list of things hit the Corvair engine world. To get to the point in the end I came to the conclusion that I could drop another 5-6 grand into the engine and still have two block half's that could not be replaced with new ones. I think Corvair would be fine if a person could get NEW block halves to build on, but as of yet no luck in that area. I scratch my head and look at the Thermo King 4 cyl. Diesel and see it puts out about 60 horse at 2800 RPM and that is without turbo. Just think of the possibilities of that engine if a person can get the weight down enough! Small inline 4 banger that the prop would love because of the RPM.096_tongue_in_cheek.gif.d94cd15a1277d7bcd941bb5f4b93139c.gif
