Apprentice STS 1.5m





Introduction
The E-flite® Apprentice® STS 1.5m is based upon one of the best platforms ever designed for discovering to fly radio controlled (RC) planes—the legendary Apprentice S 15e. That design's large size made it a perfect option for better visibility and the ability to deal with more wind while discovering to fly at an RC club flying field, and its naturally stable design plus special SAFE® (Sensor Assisted Flight Envelope) innovation made it simple to fly successfully—especially with the aid of a trainer. The Apprentice STS 1.5m is a modern-day advancement of the world's favorite club trainer that includes all the very same excellent functions while adding Smart components consisting of an ESC, battery and battery charger (battery and battery charger offered separately for the BNF® Basic variation), together with the option to include SAFE Plus® GPS-enabled innovation and the all-new Landing Assist Sensing unit (LAS), to make discovering to fly easier—and more fun—than ever before!

Overview
E-flite® took the world's favorite club trainer and made it SMARTER with the Apprentice® STS 1.5m. Based on one of the best platforms ever designed for discovering to fly radio controlled (RC) planes, its large size and 1.5 meter (59.0 inch) wingspan provides better visibility and the ability to deal with more wind while discovering to fly at an RC club flying field. Its naturally stable design plus SAFE® (Sensor Assisted Flight Envelope) innovation including Newbie, Intermediate and Knowledgeable flight modes makes it simple to fly successfully, especially with the aid of a trainer. The addition of special Spektrum™ Smart components consisting of a lithium polymer (LiPo) battery and battery charger make it easier to charge appropriately and safely (battery and battery charger offered separately for the BNF® Basic variation). And best of all it now has the option to update to SAFE Plus GPS-enabled innovation that provides functions such as AutoLand and Virtual Fence, plus the option to set up the all-new Landing Assist Sensing unit (LAS) that instantly "flares" for smoother landings, to make discovering to fly—and to land safely—easier than ever!
The Ready-To-Fly (RTF) variation includes everything needed to fly in one box, and is the perfect option if you're a brand-new RC pilot. From the Spektrum DXe 2.4GHz transmitter you can use with other Bind-N-Fly® (BNF) and BNF Basic airplane after you learn to fly the Apprentice STS, to the 3S 3200mAh Smart LiPo battery that delivers long flight times and the practical S120 USB-C Smart battery charger that can be utilized with a range of USB source of power, there's nothing extra you need to purchase or provide! A BNF Basic variation is also offered for knowledgeable pilots and clubs that want to use their favorite Spektrum transmitter together with batteries and battery chargers they might currently own. And for both variations, the effective and efficient brushless power system consisting of a Smart ESC, plus the flight controller, receiver and servos, are all factory-installed in the long lasting EPO airframe that assembles quickly and quickly without the requirement for glue or special tools.
And the fun doesn't stop after you learn how to fly! In the Knowledgeable Mode, the Apprentice STS 1.5m is capable of carrying out aerobatic maneuvers consisting of loops, rolls, inverted (upside down) flight and more. You can even set up the optional floats to take off from and land on water.
The Apprentice STS 1.5m is the smartest and finest club trainer ever, which makes it perfect for newbie pilots, experienced pilots that teach others to fly, and for club training programs alike. That's why it's the Authorities Trainer of the Academy of Model Aeronautics (AMA) and the best option for new pilots looking for a bigger trainer that makes it easier to progress into advanced RC airplanes!

SAFE technology
 

Learn to Fly Successfully with SAFE® Technology
If this is your first RC plane, Horizon Hobby-exclusive SAFE (Sensor Assisted Flight Envelope) innovation prevents over-control and crashing while also providing multiple flight modes to deliver more control and abilities as your abilities development:

Newbie Mode

In this flight mode, the plane has pitch and bank angle limitations to prevent over-control that can lead to a loss of orientation and crashes. When the control sticks are launched, the plane instantly goes back to level flight on its own allowing you to relax and take pleasure in simply 'steering' the plane through the sky. This flight mode also makes it easier to take off and land.

Beginner Mode
 

Intermediate Mode

This flight mode enables more freedom in pitch and bank, but still prevents substantial over-control and the plane does not go back to level flight on its own. This enables you to make tighter turns and to climb and descend much faster as your abilities advance. Likewise, Newbie Mode instantly triggers and returns the plane to level flight when it comes down below around 30 feet above ground level and the control sticks are launched.

Intermediate Mode
 

Knowledgeable Mode

In Knowledgeable Mode there are no pitch or bank angle limitations so you have total control! You can even fly inverted (upside down) and perform aerobatic maneuvers consisting of loops, rolls, stall turns and more. Panic Recovery can be triggered by changing to Newbie Mode and releasing the control sticks.

Experienced Mode
 

 

Panic Recovery

If you lose control of the plane in the Intermediate or Knowledgeable flight modes, simply switch to Newbie Mode and launch the control sticks. SAFE innovation will instantly return the plane to level flight.

Panic Recovery

 

SAFE technology
 

Easily Upgrade to SAFE® Plus GPS-Enabled Technology
With fast and simple installation of the optional Spektrum GPS Module you can include next-level autonomous assistance functions that make it even easier to learn to fly. With SAFE Plus added you get:

AutoLand

Triggered by simply holding down a button, the advanced AutoLand function puts the plane on a supported method to land on its own near the GPS initialization point. You can even provide some directional assistance to avoid challenges or to adjust the method while letting the system do the rest to carry out a safe landing. As your abilities development and you acquire more self-confidence you can take over more of the control inputs, ultimately discovering to land without any assistance from the automatic system at all.

AutoLand
 

Holding Pattern

This very useful SAFE Plus-exclusive function basically enables you to "pause" the flight by putting the plane into a GPS-guided holding pattern. When triggered with the fast press of a button, the plane will instantly go back to a position above the GPS initialization point and circle until the command is cancelled with another fast press of the button. It's a terrific method to safely hand the controls off to a buddy or to gain back visual contact if you ever forget the design.

Holding Pattern
 

Virtual Fence

It's simple to accidentally let an RC plane fly too far, but with Virtual Fence, worry no more. It creates an invisible boundary the plane won't fly past. When the plane reaches this boundary, it will instantly turn around and fly back toward the GPS initialization point. Then it will "wag" the wings to let you understand when you have control once again.
