Now here is something else you can do first change out the slipper clutch in the Tamiya Elevation Mech with a blue gear from the Tamiya 6 speed gearbox set you can get from Robot Market Place.

Also buy the metal arm from ETO Armor.

Then you can add limiter switches to stop the elevation mech from then tearing up the black gear from over trying to elevate your barrel .

I did this on my Tamiya Panther works good and am now doing it to a Panther II I'm building .
