Ok. I took the shaft out and rolled it on the glass pane. I did this several times and viewed it from different angles. I could not see any wobble and think the shaft is ok. However, I think I may go ahead and buy more shafts anyway and get rid of the doubt. If I weren't so busy this week I would call horizon hobby and see what they say about the issue. I still have concerns about the main gear not being straight.
I'm currently at a loss.
Tony, if it's not any trouble, on your next live stream could you demonstrate checking shaft straightness so I can see if I'm doing it right? My shaft has a larger diameter in the middle so I can't put the whole thing on the glass, just one side at a time.
