[TowerTalk] Rain Water Getting Into TX-472 Motors

[Joe Giacobello]

Fred, I had a similar problem with the motor on one of my LM-470s.  On 
one occasion I was having some sort of problem with the motor and 
removed it from its mount.  Water immediately poured out of it.  I 
allowed it to dry and reinstalled it and it has worked flawlessly since.

In talking to a former LM-470 owner from the LM-470's early days, I was 
told that water getting into the motor was a common problem.  He said 
that his complaints were responsible for Tri-Ex changing their motor 
manufacturer an/or type.  I have two LM-470s here and have had no water 
incursion problems except for the one incident above, and that seems to 
have been an isolated incident.  At this moment I can't recall the motor 
manufacturer or model, but I can get it for you if you'd like.

73, Joe
