The print calls for a 2 5/8 x 4 1/2 rectangular hole in the bulkhead sheets at the spar. The control tube will not pass through. Before I start HACKING, what am I missing ????
Hi Larry
I remember the same issue on my -4 (2004 kit ). From memory the steel control tube supplied is from an RV8 so the dimensions are a little larger than the early model-4's. I remember very slightly increasing the size of the hole in the web of the main spar , so as to get the control tube through, but it was still tight. !
Hope that helps.
