Ideal for 1/8 scale and other MOD1 pinion applications Constructed of CNC machined steel, lightened and hardened for durability Standard length shank Number of teeth laser etched on shaft. 20 Tooth Pinion Gear, M5 Set Screw.
I have several different tekno pinion gear tooth counts and they spin very true and mesh well on my rig. Hyper 10sc w/ 1/8th scale Castle motor. The cut out design allows me to change the pinion gear w/out removing the servo unlike the previous other pinion gears used.
👏
Love Tekno pinions. The bigger grub screw over the Robinson Racing pinions is the main reason I tend to buy Tekno over Robinson Racing. Both companies are top notch in gear manufacturing and you really can't go wrong with either !!!
