Hi all,
This is my least favourite operation building a kit plane or ARF. Although I've done it several times, there must be an easy way to get it right.

Getting it parallel to the wings is not that hard- eyeballing it seems good enough. But getting the distance from tailplane tip to wing tip equal on both sides always seems to give me heartache and has me spinning in circles trying to measure the distances with an ungainly long ruler or tearing my hair out as to where exactly the "tip" is on slightly rounded edge.

There must be a tried and true method out there - what, for example, is the "pull a string" method ? And any other methods that work I'd love to hear about.

Thanks
