I am using Golden Rod. And I have tried the smallest cable I could find.

But seeing as how I was impatient I am building another fin, slightly thicker, with a 90 degree bell crank and solid music wire down to another 90 degree bell crank then foward to the servo.

Thanks for the quick response.

The Bobcat kit was purchased off Ebay for $8.00 so I can't complain.

Besides its 50 miles round trip to Hobby Town , plus 30 or 40 minutes "window shopping" there.
In that period of time I can build the fin.
