Before Your First Flight
Before attempting to fly this aircraft for the first time, we recommend using the RealFlight Trainer Edition RC Flight Simulator (RFL1205, sold separately), along with the MLP6C transmitter included with the RTF version to learn and practice the basics of flying. The included transmitter may be connected to a PC for simulator use with a standard USB-C cable. Featuring six popular Horizon Hobby trainer aircraft and built-in Virtual Flight Instructor lessons, new pilots can learn to fly successfully by practicing on a PC at home or on a laptop just about anywhere else!
We also encourage you to connect with experienced RC pilots in your area through hobby shops or at designated flying fields. And for those located in the United States, we recommend joining a national organization such as the Academy of Model Aeronautics (AMA). The AMA can provide information on local clubs, instructors and established flying sites in your area in addition to insurance coverage. Visit www.modelaircraft.org for more information.

Optional Floats
To fly this aircraft off water, install the optional E-flite® Float Set (EFLUA1190, sold separately).
A rear float mount is included with the aircraft. Install it in the open slot on the bottom of the fuselage using foam-compatible CA. Refer to the float manual for installation instructions.

Float Set Not Included

Taking Off on Water
To take off on water, steer with the rudder and slowly increase the throttle.
Keep the wings level on takeoff. Hold a small amount (1/4­1/3) of up elevator and the aircraft will lift off once flying speed is reached. Avoid rapidly increasing the throttle, as torque from the motor may cause the aircraft to roll to the left when on water.
Landing on Water
To land on water, fly the aircraft to a couple of feet off the surface of the water. Reduce throttle and add up elevator to flare the aircraft.
When taxiing, you must use some throttle to create propeller blast over the rudder to steer, as there is no water rudder.
Avoid taxiing cross wind if there is a breeze, as this can cause the aircraft to flip over if the wind gets under the upwind wing. Taxi 45 degrees into the direction of the wind (not perpendicular to the wind) and use aileron to hold the upwind wing down.
The aircraft will try to face into the wind when taxiing. The wind naturally turns the aircraft to face into the wind.
