Thanks, Ken- I appreciate your point of view. If you're bored and look back around page 50-52 (PRBushwheels come up starting somewhere around there) you'll find that several people here were talking about the 6.5" tires for this 1/4 scale Super Cub. Marksp even ran a set with pics in this very thread! I wasn't the only person who was under the impression that the 6.5" tires were intended to run on bigger planes. Larry AK cUB told us to look into the 6.5" size because they were only $30, and it's his buddy that owned the company so it seemed like a credible source. Ah, hell... I just love building and flying. Life's too short to worry over little stuff. Steve at PRBushwheels seems to genuinely want to resolve my issue. Let's see where it goes next. He seems like a real modeler at heart who wants everyone to have fun.
