Hi Can't help with the part 2 plans I'm afraid, I had the same problem by the time it came to making it. The solution was to use the pictures in the article and some careful measurements to come up with a 'best guess' at it, e.g. if the tailplane width measured 25% of the wingspan in the picture then the tailplane was made that size. The result was a model which flew on rails straight off the ground the first time and which has been my son's favourite plane in the 2+ years he has been flying it. Just about the only thing he hasn't done with it is prop hang it. CofG is shown on the first plans as 7 cm back from the leading edge. Here are a couple if pictures in case they help. Terry
