Waterproof system: The whole aircraft is treated with waterproof material. The Phantom RC Remote Fighter 5.0 can fly even if its entire fuselage is submerged in water. Powertrain: A strong driveline provides ample power. Even if the plane is at 45 degrees, it can still move forward and take off. Body material: EPO body is a very durable material. The quickest advantage of this material is that it is lightweight while being sturdy. This is the first high performance RC Fighter 3.0 model equipped with exclusive Spektrum AS3X and SAFE Select technologies. The AS3X works behind the scenes to soften the effects of wind and turbulence to provide a locked-in feel that feels like you're flying in a much larger jet. Optional use SAFE Select offers tilt and bank angle limits with automatic auto-leveling that can be turned on or off with the flip of a switch, making it the easiest RC Fighter to fly! If you don't want to activate the SAFE Select features, simply connect the receiver as normal; only AS3X will be active.
