Ok guys i managed to get the rocker pivot out of the cross brace with the way Lowie did. I was able to cut a thread on the bottom of the exposed screw and slowly unscrew it and remove from underneath (thank god i didnt put to much thread lock over there

).
Now i have another issue though, trying to convert my plastic chassis to lipo stick and i m almost done. Have a problem though with my servo and servo horn. Its a KO low profile servo and the servo horn touches the shell. Have put it close to the motor. Any ideas wht i can do to overcome this?
