I know a number of you are building these now. One caution on rigging. There should be fore and aft X-bracing on the inner five sets of interplane struts (not shown on plans). However, it will be more difficult if you have to do this after all the interplane struts are in place. Instead, stop at the end of Step 4. You now have five front struts and three rear ones installed. Now do the (fore and aft) X-bracing on the inner three sets. Be careful how you pass thread up through chain drive assembly :-) When you are done with these three, glue in the rear struts on the bays that already have the front struts in place. Now X-brace them. Outer bays beyond this do not get diagonal X-bracing because it would prevent wing warping for control.
If you use the above sequence you will have a lot less trouble doing this rigging than if you wait till all struts in place.
