You need a compact motor that actually holds up past the first week of testing. This JAYCAR 6V unit spins at 9,000 RPM at max power, pushes 80g.cm of torque there, and runs on a hardened drive shaft with sintered bearings — no wobble, no premature brush wear. At 27.6mm diameter and 51mm long, it drops into tight enclosures where bigger motors simply won't fit. $15.36 RRP. If your current motor is rattling or the brushes are going, this is the swap that keeps you running
