I've never built a King Kobra before, but I'd say that would be the better bird for it since the Kougar is smaller. One thing to also seriously consider is the prop clearance. With my Kougar, I've got a OS Max .65 which takes 13" props. However with that prop, there is only 1/2 inch of clearance. I've got a 11x8 prop on it now and get about an inch and a half to two inches of clearance, still not enough to take off/land on grass or dirt, but I've got pave runway to operate on.
Overall, I'd say the Kobra and Kougar are virtually the same, just difference in size and a little in regards to the streamline. The Kobra looks a little bit more streamlined compared to the Kougar. So they are probably exact in regards to the build process. Another thing to consider too is that the Kougar can only take so much engine. I'm really pushing it with the .65, the bird was designed for a .40 - .50. The three Kougars I had built previously had only .61's in them and that was more than enough beans to get the job done. The very first one I build in the summer of '81 had a K & B .61 with a fuel pump. I didn't know a lick about any of that but was just duplicating what the heli mechanic guys had in their Kougars. Those birds were rockets and I loved how they would come in smoking hot but land flawlessly. Gee, makes me want Saturday to be here right now so I can get my Kougar out!
Hope that helps.
