Bind-N-Fly Completion Level Advantage

Bind-N-Fly Completion Level Advantage

Already own a Spektrum transmitter? Bind-N-Fly (BNF) aircraft make getting into the air quickly and with the best control experience possible easier than ever. They come out of the box with the power system, servos, and a Spektrum 2.4GHz receiver installed so all you need to do is bind the receiver to a compatible transmitter, finish any final assembly, and fly!

Exclusive Technologies

Exclusive Technologies

This UMX WACO is equipped with exclusive Spektrum™ AS3X® and SAFE® Select technologies. AS3X works behind the scenes to smooth out the effects of wind and turbulence to deliver a locked-in feel that makes it seem like you’re flying a much larger airplane. Optional-use SAFE Select offers pitch and bank angle limits along with automatic self-leveling that can be turned on and off at the flip of a switch to make this the easiest-to-fly WACO yet!

Telemetry Capable

Telemetry Capable

The UMX WACO is equipped with a control unit that includes an ESC and Spektrum receiver that provides real-time flight battery voltage telemetry to compatible Spektrum AirWare™ equipped transmitters (including the DX6e and 8e, DX6 G2/3 and 8 G2, the DX9, NX6 to 20, iX12 to 20 and others) while you fly.

Higher Performance

Higher Performance

The factory-installed brushless power system features a 2S and 3S-compatible outrunner motor. This upgraded power system setup delivers similar performance to the original when flown with 2S 280–300mAh batteries (a suitable JST-RCY to JST-PH adapter may be required), or more speed and unlimited vertical performance when flown with 3S 300mAh batteries.

Scale Finishes

Scale Finishes

The factory-finished airframe features a variety of scale details including simulated flying wires and a pilot figure with a scarf. Plus, it’s now available in two trim scheme color options including a fully-painted yellow and a lighter-weight unpainted white base version.

Lightweight Design

Lightweight Design

Construction with advanced EPS material delivers a lightweight yet durable airframe. And in the unfortunate event you damage any airframe parts or components and can’t repair them, a full line of replacement/spare parts is readily available.

Fully Factory-Assembled

Fully Factory-Assembled

The UMX WACO arrives 100% factory-assembled and ready to fly right out of the box! It’s equipped with industry-leading Spektrum™ 2.4GHz technology that binds to your 5+ channel DSMX®/DSM2® equipped transmitter so you can be flying within minutes of opening the box.

Skill Level 2 – Some Experience Required

Skill Level 2 – Some Experience Required

Skill Level 2 aircraft, like this one, are suitable for RC pilots who already have some experience and the skills to assemble and/or set up and fly similar class models. And although this is the easiest-to-fly WACO model yet, it’s not a suitable first-ever RC aircraft for new pilots or “next step after a trainer” model for low-time RC pilots. You should have the experience and skills necessary to successfully fly higher performance ultra-micro models like the various UMX Timber models, or larger models like the E-flite T-28 Trojan 1.1m, the Commander mPd 1.4m, Timber 1.5m models, or other similar class models before attempting to fly the UMX WACO.
