Motor RCINPOWER EVO 0702 31800KV/33800KV

The RCINPOWER EVO 0702 is an ultra-lightweight motor designed specifically for Tiny Whoop class micro-drones. With a minimal weight of 1.11g–1.15g and high-quality NMB 681Z2Z bearings, it provides high control precision and superior flight dynamics. There are two KV options to choose from, 31800KV and 33800KV, which combine high-tech materials and engineering solutions to ensure maximum efficiency when powered by 1S batteries. The EVO 0702 motors pair perfectly with various types of propellers with a 1mm mounting hole, delivering high power output and unmatched responsiveness.

Differences between KV versions:
31800KV - allows for longer flight times (approximately 2–3 minutes on a high-quality 1S battery) while maintaining a huge thrust reserve
33800KV - offers even more explosive acceleration, but places a heavier load on the battery and slightly reduces flight time

Features:

• A durable casing and high-quality components ensure reliability during flight
• The use of dual Japanese NMB 681Z2Z bearings ensures perfect smoothness, zero play, and durability
• The stator is made of ultra-thin 0.1mm Japanese steel laminations. This minimizes eddy currents, reduces heat, and increases efficiency
• These motors have a compact size of 11.25mm * 9.6mm and a very low weight, which significantly reduces the drone's overall mass
