RE: New Hitec servo... You asked for it, you got it!
All the gears are Titanium except for the first gear which is our revolutionary M/P gear (Shown in the picture) which is what we use in all the metal geared servos now. Be aware that all other manufacturers use an all plastic first gear.
The origional all metal geartrain did not work well because the metal to metal contact when touching the motor caused glitching in some cases. The M/P gear gives us the buffer between the motor but the metal inner pinion makes the geartrain virtually indestructable.
