I was making my RB-1 Rolling when my gasket broke, (repaired) but my problem got bigger. My servo is all screwed up. When i put gas, its good, when i applie brake, good but when i repeat the move it begin to screw up. When i make it turn right and left, Its going crazy, its going on off and and the direction is going every side and the gas goes to max and block there.

WTH Happened to it?.. [&o][&o][&o]

Help Will be greatly appreciated.
