Honestly that looks like one of those Dancing Wings or Hobbyking kits. Usually, they end up being trash. There are a lot of companies that sell well made Cub kits, and while sure you might end up spending more money upfront, you will get a better airplane in the end.
These are a couple I put together. The left one is a kit from Hobbyking that required a lot of finagling to get flying good - but fly good it does. The instructions were straight up nonexistent and the fit and finish of the kit was... sub par (I ended up making most of the plywood parts myself because of the awful diecutting) and I would personally never buy another kit off of them again lol. The right one meanwhile is a discontinued 1/5 Great Planes kit and it went together near perfectly. No fuss at all. The dog I did not build.
