Tried and True Platform

The Apprentice STS 1.5m is the smartest and most reliable radio control club trainer ever, making it perfect for first-time RC pilots. Based on one of the very best platforms ever designed for learning to fly RC airplanes, its large size and 1.5 meter (59.0 inch) wingspan offer 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.

Key Features:

  • Quick and easy assembly – no glue or special tools required
  • Ideal choice for new pilots when learning to fly with an instructor at an RC flying field, experienced pilots that teach others to fly, and club training programs alike
  • Official Trainer of the Academy of Model Aeronautics (AMA) and many clubs worldwide
  • Exclusive SAFE technology with Beginner, Intermediate, and Experienced Modes makes it easy to learn to fly
  • Powerful and efficient brushless power system, including a Smart ESC
  • Wide-stance tricycle landing gear with steerable nose wheel
  • Easily upgrade to SAFE Plus GPS-enabled technology to add AutoLand, Virtual Fence and Holding Pattern features (components sold separately)
  • Practice flying this aircraft in the RealFlight RC Flight Simulator
  • Wingspan: 59 inches (1500mm)

  • Improved ground handling for easier take offs and landings
  • Wide variety of surfaces – from paved runways to grass, and even dirt


Easy Assembly


  • Quick and easy final assembly
  • Comes mostly factory-assembled
  • Power system, flight controller, receiver and servos pre-installed

SAFE Technology for Successful Flight

Multiple Modes

Beginner: Pitch and bank angle limits prevent over-control. Airplane automatically returns to level flight when the control sticks are released. Makes it easier to take off and land.

Intermediate: More freedom in pitch and bank, but still prevents significant over-control.

Experienced: No pitch or bank angle limits – allows flexibility to fly inverted (upside down) and perform aerobatic maneuvers including loops, rolls, stall turns.

  • Panic Recovery: Switch to Beginner Mode and release the sticks if you lose control in Intermediate or Experienced modes. SAFE technology automatically returns airplane to level flight.

Spektrum Smart Battery and Charger

This RTF version includes a Spektrum 3S 3200mAh Smart LiPo battery that delivers long flight times, plus an S120 USB-C Smart charger that can be used with a variety of USB power sources. Simply connect the battery to the charger, and the exclusive Smart Technology will determine and start charging at the best rate to properly and safely charge the battery automatically.

Optional Landing Assist Sensor for Smoother Landings

The all-new Spektrum Landing Assist Sensor (LAS) is easy to install and provides automatic “flare” control to help inexperienced pilots “grease” landings by minimizing or completely eliminating bouncing (works over many/most surfaces and provides optimum performance when flying over/landing in grass).

Optional Floats

Turn the Apprentice STS 1.5m into a float plane with the optional float set (EFLA550; sold separately). Installation takes just a few minutes and all the necessary hardware is included with the airplane and float set.
