The Precision Eagle is indeed a very good engine. I have an old 4.4. Could be based on Sachs or Husky, depending on displacement. They are a bit heavier than today's r/c specific engines but in line with the older Brison engines. The P.E. hub is fairly large and, if someone wanted to invest the time, could be shaved to reduce weight further. If the price is right it's a definate buy.

Very good to know I do beleive the extra nose weight will be needed, Thanks Guy's and happy thanksgiving

Guaranteed, you will absolutely need extra nose weight on a Byron Hellcat regardless of the engine you use .... unless of course it is a small block Chevy V-8 or something like that.

Great flying airplane and in my opinion the best of the old Byron warbirds. Also quite fast for those who care about that. I built and flew one with an older 3W-60K on it ... those engines were a bit on the heavy side and I still added weight. Can't remember but I think my all up weight was 28 Lbs. or something like that.

That's what this one weighs, 26 pounds I also think Byrons Cosair is a great flyer, This is mine with a Sachs orange case 4.2

Yes, the Corsiar flies quite well. Nice looking plane. Kinda wish I had my Hellcat back. It still exists in its original form and is rarely flown by its current owner. Hmmm.... I think I pretty much gave him that plane years back .... maybe I should repo it? That was the first giant plane I flew that had almost unlimited vertical performance, even at that weight. That old 3W was strong and easily ran away and hid from the common G-62 warbird powerplant of the time. Only 3W I have ever owned.

The Taurus engines are not available at the moment. I actually called them and he said that because of the economy they are on hold.
