I agree that Horizon's web site is more difficult than some to navigate around on but I do think they do a good job of giving you the information you need. You can find the weight and size as well as recomended engine by right clicking on the "details" tab. You can download video on most of their planes. You can also download the manual. They offer an 800 number at the bottom of each page if you have any further questions and also have a "comments" tab where you can tell them what you think of their web page. All the information is there that I need when buying from them but then again I am a Graphics Designer spending an average of 10-12 hours a day on the computer.
