I'd double check your Angle Of Engagement (AOE).
Did you go for a normal, high torque or high speed gear set?
On your next setup...you might consider "dumbing" it down a bit with a 8.4v mini battery first, just to double check that everything is working right before you goose it with a higher voltage battery.
**edit**
Also...strongly consider completely removing the second tooth of the replacement piston (in your pic the second from the right). It won't affect the strength of the piston nor significantly affect the ability for the sector gear to pull the piston...and it will hedge your setup so that the first tooth of the sector clears the piston teeth to engage at the beginning of the pull stroke.

Yea, I had no idea how things were going to work out so I am not too upset that a JG piston lost it's life.
The gear set is "standard" ratio.
I am still learning my way around a gear box and as seen in my picture, the wear pattern on the piston teeth seems like the sector was catching the piston on the high side (towards the bottom of the picture). But to keep adequate spacing between the sector and spur gear....I didn't think I had an option.
Is that what you mean by AOE? The engagement angle where the sector catches the piston?
In the future, I will be sure to test with an 8.4....
