Roberto:

The Skymaster Viperjet is a great plane for somebody that is starting with Jets. The plane doesn't only look good but its also a great flyer, with no bad tendencies and its really easy to land. The Hawk is a very nice model but the Viper can be landed at even lower speeds.

Take a look at how slow a Viperjet can land http://www.youtube.com/user/jetsrc#p/u/7/-OgX8bGT0jc

Support is very important and in our region, www.jetsrc.com does a great job of supporting its customers in case of any problem (including Brazil). You never know when you are going to need spare elements for your plane so take that into consideration.
