Good working metal gears for my Heng Long Tiger I tank. Solid gears, good reduction, strong motors. Fast delivery. But only the left front gear fits on the fasting place of the 3818 tank. On the right front side there was a fixing problem, of cuase the srewholes in the gear to fix it at the tank were not at the right place for the 3818 model. But Heng Long RC is not a toy to play, it`s a tinker and screwing adventure and I fix it. After installation and soldering the motors to my tank circuit board, the Tiger I works fine.
