Rudder Blade Shape

   Keep it simple if it's your first build.  I'd recommend a NACA0010 section (google it for the section), parallel sided with a semi elliptical bottom.  Getting a nice symmetrical section is more important than planform (shape).
Chances are if you are too fussy about the planform you will end up with something that is not symmetrical in section...not good!
Have a look at the Cherub website, plenty of info on there.  Good luck!

	I am going to make a new rudder blade for my new 12. Could some one recomend me a good shape for a small lake sailed boat. I was thinking of basing it on the RS300 (RS600 also the same blade) rudder blade but making it a little bit smaller and thinner. what do people think is there a better shape? dimensions would be good Cheers Paul
