Subject: [TowerTalk] Freezing prop pitch rotor
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
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.

## Is yours a k7nv prop pitch? I have a K7NV rebuilt PP, and it has a
1/8" diam hole in the very bottom of the motor housing, which is the lowest
point of the assy.
## The K7NV rebuilt PP's appear to have some of the holes plugged up on the
sides, and yet
some other's are open, and free to drain water.
