This is the E-flite Apprentice S 15e Ready-to-Fly Airplane. The Apprentice S 15e is the most intelligent RC airplane ever offered by Horizon Hobby. At its heart is groundbreaking SAFE™ (Sensor Assisted Flight Envelope) technology that makes RC flight incredibly easy, even for the least experienced user. Its combination of spatial awareness provides flight envelope protection which adds a degree of security never before available, while its smooth flight capability battles windy conditions so that all you feel is control that’s crisp and responsive. Multiple levels of flight envelope protection are provided that can be reduced or removed as your skills progress, yet the “panic” feature is always there to instantly return the model to level flight if you ever lose orientation.

Requiring just minutes to assemble, you’ll appreciate how its quiet brushless power system delivers outstanding performance with long, enjoyable flights. Plus it’s built to last from lightweight Z-Foam™ material that’s tough enough to handle everyday flying punishment without getting bent out of shape. After you’ve mastered the basics of flight, the Apprentice S is capable of performing a complement of aerobatic maneuvers such as loops, rolls, and even inverted flight. You can also turn the Apprentice S into a great floatplane by simply adding the specially designed E-flite Apprentice S Floats (EFLA550)—sold separately.

One word for this plane "Awesome". Flys great, glides in on landings. Oh $&%# switch is just nice to have just in case. Will save your plane to fly another day.

E-flite Apprentice S 15e RTF Airplane
The glue holding the cowl/prop/motor just wont hold up. Mine barely had any glue. The lhs owner's fell off in the box. I bought extra rubber bands to hold the cowl on. Allows some flex but still holds tight. Got it stuck 50ft up in a tree and could only get 30 ft up, so I spent 20 minutes beating it with a 20ft pole since small branches had wrapped around the prop. Broke 1 servo horn and 1 clevis, that's it. This thing is tough. Fun to fly, and can adjust the throws and use the dual rate for landing. Check the battery before you charge it. My pack was at 3.8, 1.1, 3.6 out of the box. Yikes. Overall, I'm glad I bought this even with these issues.

Instructor took it off, trimmed it out, handed me the TX and I've been having a ball ever since. You need to input rudder to get her to turn at a decent rate in "beginner" mode and it seems to want to climb away a bit so I only use "intermediate" mode. The plane flies so stable and intermediate stops you from too crazy an input so the last 4 batteries have been in "intermediate" mode. First landing was in the tall grass but the rest have been right on the runway and upgrading to 3" wheels is the only hop up I put on. Just line it up and cut power EARLY because she floats like a feather. I trimmed it out to stay level at 60% throttle (gives it a little more authority in the turns)and I get 12 minute runs with power left over. If you are a total novice you may also want to put some dual rate and expo in the TX until you learn smooth, small stick movements. 75% DR and 30% EX is what I run to smooth her out.

Bought this trainer as my first plane about a month ago, all I can really say about - it's just an ideal beginner plane. Propeller, motor and esc combo is pretty strong - it has guts to quickly get you out of trouble and you can do hand launch. It stays level with about 25-30% throttle. Servos are a bit noisy, but I can't complain about their torque/speed. Transmitter - no range issues at all, takes only 4 AA's that last forever, being a full size radio it sits nicely in hands of an adult, but can be tricky to use with smaller hands. Aerodynamically I have no complaints either - If you want it can glide super slowly, if you want you can mash throttle and it still maintains stability at speed. Landing gear is plenty strong and wheels are big enough for plane to land and take-off on short grass. And most importantly: SAFE system - it basically does what is says on the box. Before my maiden flight I had only about 1 hour of flight time in simulator on my iPad(using touch controls, but I was able to successfully take-off, fly for couple of minutes to adjust trims and landed it on a narrow piece of tarmac(1-lane wide). It was like point and shoot - just what I needed. Yesterday during flight I handed TX to my buddy who has Zero experience with flying RC's and he was able to fly it no problem at all in beginner mode. Than I switched him to Expert mode - he panicked, rolled it and plane started to go 2/3 throttle straight to the ground - I just used panic switch and planed leveled itself out and everything was good again. BUT I have to warn you - to fly in beginner mode you will need A LOT of space, both for flight and landing, in beginner mode plane won't let bank too much, so turning radius is big - keep that in mind. Other than that, as I said - it's an ideal beginner plane. 10/10
