[TowerTalk] Freezing prop pitch rotor

[Zivney, Terry L.]

I seem to be having some problems with my small prop pitch rotor freezing up
When the temperature is below freezing.  I'm assuming it's a two part problem.
First, water must be getting in somehow.
Second, the water freezes when its cold.

My rotor installation looks like the fifth picture at http://www.k7nv.com/proppitch/id36.htm

So, first, how do I manage to reduce water ingress?
Second, how do I manage to heat the rotor?   I don't have 120v at the tower
And it is about 400 feet from the house.
