Water-logged Uavionix Tail Beacon

[mshac]

Well, its clear what caused it! The lower rudder cap was full of water! The drain hole had become clogged with dirt and debris. Both sides were clogged.

Uavionix sent me a canned email saying this will happen every time in certain aircraft designs because there is a hole in the back of the unit for baro.

They claim the unit is protected from water, but we shall see...

Lesson - CHECK YOUR LOWER RUDDER CAPS FOR BLOCKED DRAIN HOLES!
