Product Information

E-flite have taken one of the most popular trainers in the world and made it ever SMARTER with the release of the apprentice STS 1.5M. The Apprentice’s docile and stable flight characteristics coupled with its large 1.5m wingspan make this not only an easy plane to fly but also easy to see and orientate in the sky. The included SAFE technology gives you Beginner, Intermediate and Advanced flight modes to help you progress through the learning process and as you get better you can take more control of the model without the need for an instructor. Additionally, the Apprentice STS 1.5m has Spektrum Smart Components and has the ability to be upgraded to the SAFE plus GPS enabled system. This offers features such as Autoland and virtual fence with an option to install the all-new landing assist sensor, this sensor automatically “flares” the model to make landing safer and easier than ever before.

The perfect beginner RC plane

E-Flite Apprentice STS 15e RC plane

The Ready-To-Fly Basic version of the Apprentice STS 1.5M has everything you need to go flying included in the box except for a battery and charger. This allows you to choose a convenient and money-saving Spektrum Powerstage bundle or the separate battery and charger you prefer. Plus, the included Spektrum DXS 2.4GHz transmitter can be used with other Bind-N-Fly (BNF) and BNF Basic aircraft after you learn to fly successfully! A BNF Basic version is also available for experienced pilots who want to use their favourite Spektrum transmitter along with batteries and chargers they may already own. For both versions, the powerful and efficient brushless power system, including a telemetry-capable ESC, flight controller, receiver, and servos, is factory-installed in the durable EPO airframe that assembles quickly and easily without the need for glue or special tools.

Once you’ve learned how to fly and moved into the advanced control mode you will find out that the E-flite Apprentice STS 1.5m is a very capable aerobatic model in its own right. Loops, rolls, stall turns and inverted flight are all possible with this model! You can even chuck on some floats for water flying if you like! There’s a reason that the Apprentice has become so popular as a training aircraft, it’s just so easy to fly! With docile tendencies and a fantastic flight envelope, this model will help you learn to fly!

You can also purchase the RealFlight Trainer Edition RC Flight Simulator and a Spektrum WS2000 Wireless Simulator Dongle (sold separately) to fly this and other models using the transmitter included with the RTF Basic version. The simulator features many of the most popular Horizon Hobby trainer aircraft and built-in Virtual Flight Instructor lessons. This helps new pilots learn to fly successfully by practicing on a PC at home or on a laptop just about anywhere else!

Beginner Remote Control Plane

Progressive flight modes

Beginner Mode:

In this flight mode, the model has bank and pitch limits to prevent the pilots from over controlling the model and getting into trouble. When you let go of the sticks the model will return to level flight, allowing you to regain composure and go again.

Intermediate Mode:

The bank and pitch limits are turned down in this mode, giving you more freedom but still limiting the ability to over control the model, the model will not return to level flight on its own, allowing tighter turns and more general manoeuvrability

Advanced Mode:

In this mode it’s all on you! There are no bank or pitch limits and you can do any aerobatic manoeuvres that you like, Panic recovers and still be activated by switching back into beginner mode and releasing the sticks.

Panic Recovery:

If you lose control of the model in Intermediate or Advanced mode just simply return the switch to beginner mode and release the sticks. SAFE technology will take over and return the model to straight and level flight.

Optional SAFE Plus GPS Technology

With a simple installation of the optional Spektrum GPS Module (sold separately), you can take flight assistance to the next level. Features like Autoland help to land the model automatically from the GPS initialization point. The holding pattern feature allows you to essentially pause your flight and place the aircraft into a GPS-guided pattern until you feel like taking over again and continuing on flying. Finally, the virtual fence system keeps the model from ever being able to fly too far away and puts up a virtual block than when the model hits this point it turns around and comes back.
