00:00If you've ever had a cheap plastic gear strip out in the middle of a run,
00:03you know just how annoying it is to fix toy motors.
00:06Upgrading to solid metal is an absolute game-changer, so today, I've tracked down the
00:11best deals on the top 5 copper pinion gears for toy motors that will keep your favorite RC cars,
00:15slot racers, and DIY builds running smooth without costing you much at all.
00:20First up is a 10-piece set of 0.4 modulus brass spur gears that gives you an incredible amount
00:26of flexibility. The best part here is the tooth selection, you can choose anywhere from 9 to 18
00:31teeth with a tight 1.98 to 2mm bore that presses cleanly onto standard toy motor shafts.
00:37For just $5.94 for 10 pieces, it's a total steal and an easy way to tune your gear ratios
00:43for the
00:44exact balance of speed and torque you need. Next, if you're working on micro-scale projects,
00:49check out this 5-pack of 14-tooth 0.3 modulus brass pinions.
00:53The standout feature is its ultra-compact 4.8mm outer diameter with options for either 1.5 or
01:002mm shaft holes, making it a drop-in replacement for tight assemblies.
01:05Priced at only $2.65, it's ridiculously affordable, and the precise machining ensures
01:11smooth meshing without adding unnecessary weight to lightweight builds.
01:15Third on our list is this heavy-duty 5-piece pack of 0.6 modulus 9-tooth copper gears.
01:21What makes this gear shine is its beefy thickness, giving you up to 6mm of face width for maximum
01:27contact and grip under heavy loads. Coming in at just $2.99, it's well worth the pickup if you're
01:34building high-torque robotic arms or upgrading geared gearboxes that keep stripping out standard
01:38teeth. Moving on to number 4, we have a specialized copper worm gear designed for extreme reduction
01:44setups. Unlike standard pinions, this helical design allows for smooth, quiet right-angle
01:50power transfer and self-locking mechanisms, with sizes ranging from 0.2 up to 0.7 modulus.
01:56At $3.14, it's a fantastic value for custom steering units, mini winches, or any project where you need
02:04serious holding power in a tiny footprint. Finally, rounding out the list is this 17-tooth 0.6
02:10modulus copper gear, which stands out thanks to its wide variety of larger bore sizes.
02:16You can grab it with a 3, 4, 5, or 6mm center hole, making it ideal for stepping up to
02:22larger
02:22toy motors and custom drive shafts. At just $2.73, its tough solid copper build and versatile mounting
02:29options make it an awesome upgrade that will easily outlast the rest of your toy chassis.
