RCG Racing Tracer / MT-One Bánh Răng Nhông Động Cơ (14T) & Vít Định Vị Cho Động Cơ Không Chổi Than

I've stripped the old motor pinion down to the shaft and back maybe five times now, and the set screw still bites hard without stripping. The 14T mesh is spot-on with my brushed-over brushless swap, and it's a relief to have a spare that's genuinely drop-in for the MT-One chassis.

Fits both my Tracer and the Slyder without any fuss, which is handy since I’ve got both on the shelf. The 14T pinion and grub screw are solid enough for the price, though I wish they’d thrown in a spare screw or two for that money.
