Lucky Me
I never would have figured it out if it was not for my flying buddy who has a Raptor 60. He told me about the set screw and I never would have thought if it otherwise.
It is a shame that the manual is so weak. I think it will take a lot of failures for Thunder Tiger to make a separate manual for the 50 which they should have done in the first place. While they are at it they need to redo the 30 manual too.
