Gearbox dual speed dinamo 390 RS | Rc d90 upgrade dinamo

Hello Tips, Tricks, and Tutorials friends, in this video, I'll be upgrading a basic 370 dual-speed motor, and I'll be upgrading it to a 390 motor. The 390 motor uses a 2mm shaft and a 1.9mm hole diameter pinion for the dual-speed motor. This automatically requires a smaller 390 motor shaft. Materials for reducing the size: 1. Rough sandpaper 2. Flat file 3. Vise 4. Electronic ESC, etc., to operate the motor. Pinion purchase link: https://shopee.co.id/product/16600664...
