Seagull and Phoenix (and Black Horse) are sister concerns. They have recently updated their line-ups. The MX-Rs are new models. I dont think anyone will have a review for you. But typically, Phoenix are the sturdier ones (meant for the asian markets) and Seagull / BH are lighter (for US markets / paved runways). They are very good quality for the price and if you are an experienced modeller, you shouldnt have oo many problems with the iffy manual
