E-flite Apprentice STS 1.5m Smart Trainer Plane with SAFE Technology (RTF) - EFL3700

Pre-Order E-flite Apprentice STS 1.5m Smart Trainer Plane with SAFE Technology (RTF) - EFL3700

E-flite Apprentice STS 1.5m Smart Trainer Plane with SAFE Technology (Ready-to-Fly)

E-flite® took the world's favourite club trainer and made it SMARTER with the Apprentice® STS 1.5m. Based on one of the very best platforms ever designed for learning to fly radio controlled (RC) airplanes, its large size and 1.5 meter (59.0 inch) wingspan offers better visibility and the ability to handle more wind while learning to fly at an RC club flying field. Its inherently stable design plus SAFE® (Sensor Assisted Flight Envelope) technology featuring Beginner, Intermediate and Experienced flight modes makes it easy to fly successfully, especially with the help of an instructor.

The Ready-To-Fly (RTF) version includes everything needed to fly in one box, and is the perfect choice if you're a new RC pilot. From the Spektrum DXe 2.4GHz transmitter you can use with other Bind-N-Fly® (BNF) and BNF Basic aircraft after you learn to fly the Apprentice STS, to the 3S 3200mAh Smart LiPo battery that delivers long flight times and the convenient S120 USB-C Smart charger that can be used with a variety of USB power sources, there's nothing extra you need to buy or provide, the powerful and efficient brushless power system including a Smart ESC, plus the flight controller, receiver and servos, are all factory-installed in the durable EPO airframe that assembles quickly and easily without the need for glue or special tools.

Beginner Mode
In this flight mode, the airplane has pitch and bank angle limits to prevent over-control that can result in a loss of orientation and crashes. When the control sticks are released, the airplane automatically returns to level flight on its own allowing you to relax and enjoy just 'steering' the airplane through the sky. This flight mode also makes it easier to take off and land.

Intermediate Mode
This flight mode allows more freedom in pitch and bank, but still prevents significant over-control and the airplane does not return to level flight on its own. This allows you to make tighter turns and to climb and descend faster as your skills advance. In addition, Beginner Mode automatically activates and returns the airplane to level flight when it descends below approximately 30 feet above ground level and the control sticks are released.

Experienced Mode
In Experienced Mode there are no pitch or bank angle limits so you have complete control! You can even fly inverted (upside down) and perform aerobatic manoeuvres including loops, rolls, stall turns and more. Panic Recovery can be activated by switching to Beginner Mode and releasing the control sticks.

Panic Recovery
If you lose control of the airplane in the Intermediate or Experienced flight modes, simply switch to Beginner Mode and release the control sticks. SAFE technology will automatically return the airplane to level flight.
