The Polaris EX can be ordered as a prop version or EDF version. The kit will include one motor mount for that version. If you want to be able to switch between prop and EDF you will need to purchase a second motor mount listed above.
Note that a selection is required in each category above, even if the selection is "None".
Were excited to introduce the Polaris EX seaplane parkflyer! Based on the Polaris design by Steve Shumate and inspired by Laddie Mikulaskos North Star seaplane, weve incorporated some design changes worthy of a new model!
The most notable feature of the Polaris EX is its 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.
Recommended power setups include:
Spin Max (Suppo) 2212-06 motor (high power), 1800 to 2200 mAh 11.1V lipo battery, 40 amp ESC with heat sink, APC 6x4E prop
Spin Max (Suppo) 2212-10 motor (mid power), 1300 to 2200 mAh 11.1V lipo battery, 30/40 amp ESC with heat sink, APC 7x5E prop
RC Lander 68 mm 10 blade EDF, 2500 to 2700 mAh 11.1 lipo battery, 70 amp ESC
Note that to achieve top performance, EDFs require a higher quality battery relative to prop driven planes. We recommend a 45C or higher rated battery.
