Can you please explain?
I always thought the xtx50 octi just used a diffrent cover. I never thought Apeks would go to all the cost and trouble of making a less robust 2nd stage just to sell as an octi.
Detuned maybe but thats not an issue.
With the exception of the color of the face plate, the venturi lever, and the center of the exhaust housing, an Apeks octo and primary second stage are identical.
