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.
