Hi James,
I build a scratch legacy, used carbon veil with dope. I running a ST 51 and it flys the plane very well. The carbon veil is very strong, if you put it on correctly. Remember to put three coats of clear on the wood than when you apply the carbon veil use clear with 90% thinner. When you sand the carbon be careful not to sand thru the carbon, cause if you do you'll have a lot of fun. Don't ask me how I know???
Good Luck and enjoy the Legacy cause shes a great flying plane!
Gary
