Here's the link to the spinner I'd suggest at Tower Hobby's online catalog. It's even red. The only bad news is that they're only available in 2 blade. Don't fret the Zinger prop... sometimes they are just what the Doctor ordered...not too efficient, so slower lap time than an APC, for instance. The picture of the spinner is just a link to the one I posted on the link that Ion posted. The 2" weighs 25g., and is $5.79US. I came back and posted your new Cardinal pics here, because they are so slow loading. I did a minor crop, resized to 650 pixel width, and compressed to about 40kb. Nice film job! What kind of film did you use? (Leon, take note, it's not paint!)
