I figured as much, besides the head the engines look identical. I just have to see which gives me a better discount at my store, horizon's engines or LRP's, lol.
Only thing I don't like is the pullstart on my .26. It ALWAYS comes unstrung and I have to bump-start it. I'm afraid that if I get another .26 or a big red, that its pullstart will come unstrung too. And since I can't exactly bumpstart it, that's a problem.
