May I suggest there is one more thing to do before you cast your plane to the winds. Take you plane to an RC Club, find the resident "test pilot" (most clubs have one or two really knowledgeable guys) who can give an "eyes/hands on" inspection. Then, if it passes inspection, ask him to do the maiden flight. He then will be able to give you sound advice based on his experience.

Live long, and prosper
