I want to thank everyone for their help. I got it downsized and will try to post the picture again.

keep them flying, Randy

Has anyone built Piper Cub J-3 f or Controline Scale? If so what plans did you use and how big? Are there R/C kits out there that could be used? I have one of the SIG kits, but its a little bigger than I wanted to use, something more in the 50 inch wing span area.

Wasn't on Stuka -- I never warmed up to that group.  Did I ask about this, or was it someone else?

Yes, he knew, you had to ask him, he wrote it aproximately 6-7 years back either here or on stuka. He also had feedback regulator using that ... used I think 2010 in Hungary, may be Dave F. or other guys will tell why he decided to use something else :- )))

 I had that exact combination around 1954-55 The .29 runs good for stunt but is not as powerful as a Fox 35. Just use shorter lines if you need to. Mine had the original rings so yours should be better than mine was. The rear intake takes up a lot of room but the Mustang has more room because of the lower wing.
  Show us a picture.

Sorry Frank. I saw McCoy and went into Red Head mode    Yours is a Duramatic production McCoy. I think he went with Testors in 1956 or so, or more likely, Testors bought Duramatic.. Not sure. The Duramatic engines looked like somethingout of the 40-50's era. They had character and were good engines.  Better fits and quality. Not sure if you new this,,,,,,,but Dick McCoy flew a model airplane once. He was into tether cars big time and his engines were the thing for those cars along with Orwick, etc. I know of two places on the West Coast that still run them. 

     Hello:

     Thanks for the replies.

      Ty, I have no idea as to what kind if McCoy that I have.  I doubt that it is a Testors as it is a 1950 model and not a 1949 model.  This model has a rear venturi that is angled up at about 45 degrees.  I like having the needle valve far away from the prop on this model. The nva on the Cub .19 is a real challenge to adjust as it is so close to the prop  I do not remember if the McCoy Sportsman had any ball bearings in the case.  I have a rear induction .36 that has two sets of ball bearing installed.  This engine ran very poorly on no nitro fuel.  When given fuel with touch of nitro, the engine came to life.  I will try fuels with 5-10% nitro to see how well it runs.   

      I also have a couple of the Sportsman? McCoy .19 engines with the straight venturi mounted on the rear of the case.  I ran these several years ago and they were very low on power due to very poor ring fit.  Perhaps they will improve with more running time on them.  It is very large loss now that Mr. Bowman is not making rings.  Perhaps some person will purchase his equipment and continue this very valuable service.

      Any idea as to how long I should run these engines to get the rings seated? 

                                                                                                                                 Be well,

                                                                                                                                 Frank McCune

     

Thanks so much Motorman.  I sent it to him.  He cleaned it out on the inside.  No more binding but great compression. I hope to run it this fall.  However, the Fancherized Banshee it was on is waiting to have a new elevator put on.  The original elevator was not even and I left it go.  However, the plane wouldn't stay on the end of the lines above my head. Can't wait to try the LA 40 again.  It was so easy starting and ran well.

Oh, yes.  That one.  (D'oh)


It needs to be that fancy for more or less the same reason that a milling machine needs all those knobs and buttons.  If all you've ever needed was a drill press, that milling machine is way too fancy.  You can do anything with Gimp, including starting from a white background and hand-making a picture.  If all you're ever going to do is resize, it's way too much.

I believe the RSM ME-109 is Charles Mackey's version.
