Re: Light-Sport Aircraft Yahoo group lightweight engines

It would be interesting to know how they are cooling this engine. The amount of reject heat is the same for 80 HP no matter how much the engine weighs. Look at the cooling fin area on something like a VW or Jabiru 2200. That's what it takes unless you go water cooled.
