Yes I'm going to be picky : What you listed as a back wing is the " horizontal stabilizer " , the back wing elevator is just the "elevator " , what you listed as the rudder is the " vertical stabilizer " and what you listed as the rudder aileron is just the " rudder ". Hope this helps in your venture , you need correct nomenclature if you are going to design kits for other folks to build. I didn't comment about the " front wing " or " back wing "~~ you can do a little research on your own to correct them . I hope this will help in the future . ENJOY !!! RED
