Home / RC Accessories / Brushless Motors / Ripmax Quantum Brushless Motor Product Description This is a higher RPM, Speed version of the Quantum II 25 motor for high power/speed flight. It is ideally suited to the Ripmax Easy Street II with either 3S or 4S Li-Po batteries. Due to the higher current this motor requires, it needs a 60A ESC rather than the 40A ESC used on the standard version. On 3S it works well wirth a 10" x 7" E APC propeller but if you want more performance we suggest a 9"x 7.5" E APC propeller on 4S for some extra punch! The Ripmax Quantum II range of electric motors are designed to offer performance, efficiency, build quality and value-for-money in a wide array of sizes. Every motor includes a mounting kit comprising of a tough metal motor mount and a CNC metal prop adaptor that bolts to the can.
