I just finished building the Sig LT-40 Kit the other day. Let me honestly tell you that I would not want to set it next to the ARF version. My covering job did not turn out near as good as what they could have done at the Factory. I have covered several of my own Planes, and covering is just not my specialty. Some people are good covers and some people are not no matter how hard they try. I for one am not. I just hope my building skills were right on to make this a good flyer. I think the ARF version of this Plane has been on many "good" list, so if the kit version don't fly well then I can only Blame myself. Anyway I would be interested to hear if anyone has had a bad experience with the Sig LT-40 ARF, or Sig ARF's in general. I have not heard to many negative things about Sigs Planes. Does Sig have anything that should belong on the "Avoid at all cost" list, or are People that happy with all the Sig ARF's?
