Model Aero Polaris Ultra ARF

Posted by: Jon Barnes

Based on Laddie Mikulasko’s legendary North Star design, this is an ARF version of the popular Polaris seaplane scaled to 115% of Steve Shumate’s original design. Molded of high quality EPO foam, it can be built in a fraction of the time of the original Polaris kit. As with all Polaris models, it can fly off water, grass, or snow! The Polaris Ultra retains all of the flying qualities of the original Polaris, yet has a character all her own.
