You are in the kit building forum, not the ARF forum. If you went into the ARF forum you would find a lot of people that have assembled the same plane and probably know all the little details. I have assembled a few of there Extras and the instructions were so funny my wife made a copy to take to work and show to her crew for a laugh at the Chinglish. Outstanding engine by the way. Never met a DLE I didn't like, once we changed the apark plug.
