                                                    Polaris EX Introduction

  

 
We’re excited to introduce the Polaris EX seaplane parkflyer! Based on the Polaris design by 
Steve Shumate and inspired by Laddie 

Mikulasko’s North Star seaplane, we’ve incorporated 

some design changes worthy of a new model!  
 
The most notable feature of the Polaris EX is it’s power system flexibility. It can be built as a 
prop plane or EDF utilizing the new 10 blade RC Lander 68 mm EDF. And the power systems 
can be swapped out in less than 10 minutes! She flies equally well on both power systems but 
we prefer the incredible sound of the new lightweight  EDF. With an AUW of 28 oz. the EDF 
performance is exceptional! 
 
The kit features simple sheet foam construction and the plane boasts excellent handling 
qualities, both in the air and on the water. In flight this model is smooth and stable, yet also 
very aerobatic. On the water it tracks straight as an arrow and takes off and lands effortlessly.
