Zulu ET plan builders should be aware of an error in the plan published with the October issue of RCM&E. The model, a sport/trainer has two formers that were incorrect.
That's the bad news but the good news is that designer Lindsay Todd is running a step-by-step, photo build blog (link below) and here you'll find the correct former measurements. F4 and F5 are those affected for which the correct measurements are on page 2 of the blog. Please accept our sincere apologies for this.
