Odyssey 1 Lurch

If the ring is not cracked I would leave it alone. If the only issue now is the slight lurch its likely not even cracked.

Have you tried running it using a Legacy controller?  The old CAB1 only runs in relative mode and exacerbates the lurch over the TMCC mode of the Legacy system.

Thanks for the feedback.

John, no, I don't have the Legacy system just the old TMCC and Cab 1. Now that you mention it, I think I read that the lurch was not an issue with the Cab 2/Legacy system.

Is that correct?

Pete- even if the ring is not cracked, isn't it prone to shattering and best removed if installing the ERR "M"?

Thanks,

Mack

It won't hurt anything to remove the ring, it's easy, one squeeze with pliers and it will break off.

I wouldn't say the Odyssey I lurch is totally cured with Legacy, but it's not nearly as obnoxious using the Legacy system.  I don't know about the new BASE1-L/CAB1-L system, I'll have to try that some day.

I have seen a few broken magnets but am not aware they shatter. I am a believer if its not broke don't fix it. I have found that if you watch the TMCC base for the first blink then wait before turning the red knob for the engine to start you can minimize or eliminate the lurch. The lurch is caused by inputting too many steps bfore the engine has a chance to respond. Try it.

I have seen the aftermath of one shattering, they do come apart if you happen to be highballing at the time it breaks!  It did a bit of damage to a board and put some noticeable dents inside the shell.  Must have been a bit of force behind it.

Thank you again, gentlemen, for the great guidance and advice. Much appreciated.

Yep, I had a desert storm SD-40 that the ring shattered, as it shattered the pieces shorted the motor driver board. It was like hitting the self destruct button.

I was able to repair the board, it chopped off a couple of components. 

I've had a CD explode in a CD drive, must be a similar bang for the magnet ring.  When you spin something at a high rate of speed, there's a lot of energy available if something lets loose!
