These pictures are not mine. I got them from www.vansairforce.net fourms at the following link. http://www.vansairforce.com/community/showthread.php?t=42124&highlight=rudder+stop
Craig Vincent makes these and sells them. You can email him at Craig@StocktonEAA.org
He charges $25.00 and that includes shipping.

I priced the material at Mcmaster Carr and I can get 5 feet of this stuff for less then $3.00. Don't know what shipping is yet. I almost bought one of Craig's but at the last moment I thought "Hey, I'm an airplane builder. I'll make my own". When I'm showing off my alternative rudder stop I'll be able to say "I made it myself, it's a Craig Vincent design".
