RCinpower EVO 0702 31800Kv is a lightweight motor suitable for 1S 65mm Tinywhoops with 1.2" tri-blade propellers. It weighs only 1.15 grams without wires, making it ideal for ultralight builds for indoor racing and freestyle. The 7x2mm stator with a 9N12P configuration is made of thin 0.1mm steel laminations that reduce magnetic losses and improve efficiency. The 1mm diameter shaft rotates in two NMB 681Z2Z bearings for smooth operation and longer lifespan.
At 4.2V with an HQProp 1.2x1x3 propeller, the motor delivers up to 41g of thrust at a current draw of 5.3A. Its highest efficiency, over 84%, is in the 1-2A range, corresponding to low and mid throttle.
The motor is mounted with three M1.4 screws on a 6.6mm mounting pattern. With a diameter of 9.6mm and a length of 7.8mm, it is among the smallest brushless motors for FPV.
