RCINPOWER EVO 0702 33800KV Brushless FPV Motor – 1S Tiny Whoop

High-performance 0702 33800KV brushless motor for 1S 65mm tiny whoops, featuring a 1.15g lightweight design, precision NMB bearings, and up to 43g of thrust. The RCINPOWER EVO 0702 33800KV Brushless FPV Motor is built for pilots who demand fast throttle response, powerful acceleration, and precise control from their tiny whoop racing drones. Designed for 1S 65mm whoops using 1.2-inch tri-blade propellers, the EVO 0702 33800KV combines a lightweight motor design with high-quality bearings and a 9N12P configuration. Its high KV rating makes it particularly suitable for competitive indoor racing and aggressive freestyle flying. Key Features 33800KV Performance: High-KV winding for rapid motor acceleration and responsive throttle control. Ultra-Lightweight: Weighs approximately 1.15g without wires, helping minimize aircraft weight. Designed for 1S: Optimized for compatible 1S LiPo-powered tiny whoops. 43g Maximum Thrust: Produces up to 43g of thrust with an HQProp 1.2x1x3 propeller at 4.2V under test conditions. 9N12P Motor Configuration: Nine-slot, twelve-pole construction for efficient brushless performance. 0.1mm Stator Laminations: Thin steel laminations help reduce magnetic losses. Dual NMB Bearings: Two NMB 681Z2Z bearings support smooth rotation and durability. 1mm Propeller Shaft: Compatible with appropriately sized 1mm-shaft propellers. Standard 0702 Mounting: Three M1.4 mounting holes on a 6.6mm diameter pattern. Compact Construction: Approximately 9.6mm diameter and 7.8mm overall height.

Its high KV rating allows rapid propeller acceleration, making it suitable for tight indoor race courses, fast direction changes, and technical freestyle maneuvers. 33800KV vs. 31800KV Compared with the EVO 0702 31800KV version, the 33800KV model delivers faster propeller response and approximately 2g more maximum thrust under the retailer's stated test conditions. With an HQProp 1.2x1x3 propeller at 4.2V, the 33800KV motor produces up to 43g of thrust while drawing approximately 5.6A. The higher-KV version draws approximately 0.3A more current than the 31800KV version under the comparison conditions. Precision Bearings and Efficient Stator Design The motor features two NMB 681Z2Z bearings for smooth shaft rotation and consistent performance. Its 0.1mm stator laminations are designed to reduce magnetic losses and improve motor efficiency. Peak efficiency exceeds 84% in the approximately 1–2A current range, making the motor well suited for pilots who want efficient operation at low and mid throttle. Lightweight 1S Performance Weighing approximately 1.15g without wires, the EVO 0702 helps keep total aircraft weight low. Its 1mm shaft and standard three-hole 0702 mounting pattern make it suitable for compatible tiny whoop frames and propellers. Because the 33800KV version can draw relatively high current for a 1S motor, use a battery with sufficient discharge capability and verify ESC compatibility before installation. Recommended Applications Competitive indoor tiny whoop racing 65mm 1S brushless whoops Lightweight freestyle builds High-performance 0702 motor upgrades Custom micro FPV racing drones Package Includes 1 × RCINPOWER EVO 0702 33800KV Brushless FPV Motor Important Notes Price is for one motor, not a set of four. This listing is specifically for the 33800KV version. Designed for compatible 1S tiny whoop applications. Maximum thrust figures are based on specific test conditions and propellers. Motor weight of 1.15g excludes wires. Confirm motor mounting pattern, propeller shaft diameter, ESC current capacity, and battery discharge capability before purchasing. Propellers, batteries, ESCs, and other drone components are sold separately. Frequently Asked Questions Is this motor suitable for a 65mm tiny whoop? Yes.
