I'm pretty sure that he is asking if ESM models are as good of quality as Kondor Model Products airplanes. The answer is ESM is the same as KMP, which is the same as YT International; they are just different names given their location around the world. I dont have any ESM/KMP planes but I wouldnt be affraid to buy one and most people I have heard talk about them say that they are very good quality planes. Hope this answers your question.
