Paul --
Check the article on my website called:
"Repairing a Tail-Twister Rotator" at:
http://www.hayseed.net/~jpk5lad/Rotors/Tail-Twister.htm
I showed how some teeth were chewed out of the
stainless steel ring gear which caused mine to not turn all
the way.
There are quite a few pictures of the process including
some of the actual ring gear.
Good luck and 73,
Jim - K5LAD
