The first "bigger" 3" motor designed for cinematic smoothness, while still balancing efficiency and power. Created specifically for the Acrobrat frame, this motor’s priority is to deliver the smoothest operation out of any 1407 on the market. Smooth operation means fewer vibrations. Fewer vibrations mean less “noise” for your flight controller to deal with. Less “noise” means better performance and better efficiency. Most importantly, less “noise” means less jello for your CMOS camera (ie – the Runcam Split Mini)!

When paired with the HQProp 3x3x3 or RotorX 3044tx, expect ultra smooth performance without compromising power. That’s the magic that RotorX x Hypetrain brings to the table.
