About this part

Experience upgraded thrills with E-flite's WACO

E-flite Ultra-Micro UMX Waco Electric Airplane. Get ready for an enhanced flying experience with the upgraded E-flite UMX WACO! Now featuring optional-use SAFE Select for added stability and exclusive Spektrum AS3X for a smooth ride, it feels like piloting a larger model, even in windy conditions. The factory-installed brushless power system boasts a 2S- and 3S-compatible outrunner motor. Opt for 2S 280mAh batteries for original performance or go for 3S 300mAh for increased speed and unlimited vertical action. The control unit includes an ESC and Spektrum receiver with real-time flight battery voltage telemetry. Constructed from advanced EPS material, it's lightweight yet durable, available in painted yellow or unpainted white versions. This Bind-N-Fly Basic model comes 100% factory-assembled, ready to bind to your 5+ channel DSMX/DSM2 equipped transmitter, ensuring you're airborne within minutes of unboxing! Perfect for indoor gymnasiums or outdoor spaces, this lightly loaded biplane design offers versatility from yards to parks and sports fields.

Designed for RC pilots with a Skill Level 2 proficiency, this aircraft is ideal for those with prior experience assembling, setting up, and flying models in a similar class. While it's the most beginner-friendly WACO model, it isn't recommended as a first-ever RC aircraft for newcomers or as a "next step after a trainer" model for low-time RC pilots. To tackle the UMX WACO, it's essential to have the experience and skills gained from successfully flying higher-performance ultra-micro models like the various UMX Timber models or larger counterparts such as the E-flite T-28 Trojan 1.1m, the Commander mPd 1.4m, Timber 1.5m models, or similar class models.

Features:

  • Officially licensed scale replica of the modern-day yet classic YMF-5 biplane design
  • Real-time battery voltage telemetry with compatible Spektrum transmitters
  • Spektrum receiver with industry-leading 2.4GHz DSMX technology
  • Unmatched stability and locked-in feel of exclusive AS3X technology
  • Compatible with the Spektrum DXS transmitter
  • Easier to fly with optional-use SAFE Select flight envelope protection
