Congratulations on choosing the E-flite

 Apprentice
®
 S 15e airplane. Within 
your grasp is the most intelligent RC airplane ever offered by Horizon 
Hobby. Based on the renowned original Apprentice model, at its heart is 
groundbreaking SAFE™ (Sensor Assisted Flight Envelope) technology that 
makes learning to fly RC easier than ever and more fun for the experienced 
pilot too. That’s because SAFE technology makes the complexity of model 
aircraft spatial awareness possible so that you get the innovative benefit of 
flight envelope protection, smooth flight performance and more. 
Multiple levels of flight envelope protection allow you to reduce or remove 
assistance features from the transmitter instantly so your skills can progress 
more quickly. In addition, a “panic” feature is always ready to instantly return 
your model to level flight if you ever loose orientation. 
Patented Z-Foam™ construction of the Apprentice S offers durability beyond 
comparison. Spektrum

 DSMX
®
 radio technology means that you get the 
assurance of an interference-free 2.4GHz signal for industry-leading command. 
Because great control is more fun with power, count on the installed E-flite 
electronics and power system to deliver crisp response of your transmitter 
commands, and the performance to make it more fun. 
All you have to do next is read and apply the information presented in this 
instruction manual. Once you’ve learned the basics of RC flight, feel free to 
enjoy this aircraft to learn more advanced maneuvers. You can also consider 
flying from a lake or pond by installing the optional Apprentice S Float Set 
(EFLA550), available separately.
