I built the Sig 1/6 scale kit and found it a joy to build, but this kit is not for the person who does not have alot of time and kit building experience. (I just love to built kits). The 1/5 scale sig kit is a great laser cut kit and builds quickly. The parts seem to almost put themselves together, unlike the 1/6 scale kit which is a stick build kit. I find that both kits fly just like a cub should. If you want a more scale like cub take the 1/5 scale sig. It is a great kit. Here is a picture of the 1/6 scale I built that took a year to put together working off and on on it.
