How-to Waterproof the E-Flite Apprentice S 15e with Floats and Test Flight

After substantial flight hours on my E-Flite Apprentice S 15e with AS3X and SAFE, I took action against a repeat problem of water intrusion into my control electronics.

A few days earlier, I had a near, catastrophic failure of flight control while flying over Benton Lake. During the taxi into shore, the servo failure changed from intermittent, to total failure. The stock design of the Apprentice S provides poor protection of the electronics from the natural water splash created from the factory built float usage.

My first goal was to restore the electronics to functional operation which happened as soon as the electronics were dried. My second goal was to keep them dry by adding some water resistance to the two servo motors. My third goal was to prevent water from showering my electronics to begin with.

In this video, I display my final result of multiple barriers that radically reduce the water exposure of the Apprentice S electronics while still providing adequate ventilation to electronics and battery. I wrap-up my video with a demonstration of the effectiveness of my work while also demonstrating the unaffected flying characteristics after the changes.

After highly recommending this aircraft as a “float-plane”, I highly recommend performing similar modifications to all Apprentice models used on water. I believe that this is how these aircraft should have been factory delivered to maintain a “safe” flying aircraft that was marketed for water use.

Please browse my other videos on my Apprentice S play lists for my other modifications and recommendations.

SAFE flying!
