    My son, Jon, has been flying for almost two years. He has been doing very well on his Flyzone Skyfly Max, but now he is looking for something larger to fly. I do have a nitro-powered trainer sitting in my "hanger", but at this point he seems to be interested in flying electric aircraft only. As he is only 10 years old, I feel better with him flying electric, because he doesn't have to start a nitro or gas engine. I like the fact that all he has to do is plug in the battery, and he's ready to fly. Since he wanted a larger plane, I started looking around for a high quality 4-channel plane that will fit his needs. It had to be something relatively easy to fly, but it also had to be able to keep up with his growing skills.

    A few weeks ago, while looking at my options for a suitable plane, I came across the Flyzone Sensei. The Sensei is an all new aircraft offering from Flyzone, and it comes in Receiver-ready (Rx-R) and Ready-to-fly versions. The Ready-to-Fly version comes with the new Tactic TTX 600 6-channel radio system, while the Rx-R version lets you use your existing transmitter.

    My son can hardly contain his excitement any longer, so let's get this box open and see what we've got!

    • Brushless Motor, ESC, and Servos Pre-installed

    The Sensei is well packaged in a nicely adorned box. All pieces of the plane were individually wrapped in bubble-wrap to prevent damage during shipping, and mine arrived in great shape. There are very few parts to assemble - I expect it will go together quickly, so my son can start flying!





    There are several features on the Sensei that caught my eye right out of the box. The color scheme is attractive, all of the control surfaces are pre-hinged, and all of the servos are pre-installed. The aileron pushrods are already connected as well, saving lots of time!






    The wing joiner is very tough, but lightweight as well, and the center section locks the wing panels together. It was also cool to see the main landing gear ready to bolt on, and all of the servo wires are labeled for 'no-guess' connections!



    I also liked the drop-in battery compartment, the pre-installed brushless outrunner motor, and the large cargo bay and servo-operated 'bomb drop' opening doors!


    Manual


    The manual is very informative - the illustrations are clear and the written instructions are so well done that almost anybody can assemble the Sensei. It also includes a section that will guide you through the first flight, but it's best to get help from an instructor at a flying club if this is your first plane.





    RECEIVER INSTALLATION


    This one was a first for me. Installation of the receiver is not usually in the front of the assembly manual, but on the Sensei, it is. Plugging in all the servo wires was easy, thanks to the labels by each plug! Once all my connections were made, I secured the receiver using the included double-sided tape, then tucked the wires under the servo tray.



    MAIN LANDING GEAR INSTALLATION



    Since the wheels are pre-installed, all I had to do was attach the gear with the two included machine screws.


    TAIL INSTALLATION





    After flexing the control surfaces a few times to make them move easier, the stabilizers are assembled as a unit. At this point, they were ready to be joined with the fuselage.





    Installing the tail assembly couldn't be easier! The rounded tip of the vertical stabilizer slid into a groove in the fuselage, and a single screw locked everything together.






    Connecting the pushrods to the control horns was the only area I had trouble with on the entire plane - not because of its design, but because I have clunky fingers that don't get into small places very easily. With that said, connecting the pushrods is a straight-forward step that will take very little time for people with average sized fingers!



    WING ASSEMBLY





    This step takes almost no time at all. The joiner tube is slid into one wing half, the other half is slid onto the joiner tube, and the plastic connector is snapped in place from the top of the wing. That's it!


    FINAL TOUCHES





    After connecting the aileron servo wires to the included Y-harness, the wing is installed on the fuselage using two nylon bolts placed in the plastic connector in the wing.

    I adjusted all the control surface deflections per the manual. Since I used a Futaba radio system with the Sensei Rx-R, I set all the deflections through my transmitter.





    We're almost done! The propeller adapter, prop, and spinner were added to complete the Sensei. As I do before flying any new plane, I checked the Center of Gravity (CG) per the instruction manual. Normally, the CG is marked by a measurement from the leading edge of the wing, next to the fuselage. The underside of the wing has been pre-marked, so finding the balance points is easy. For the record, with the battery installed and the plane ready to fly, my Sensei balanced perfectly!

    Let's take her out into the sun, take a few pictures, and see how she flies!




    As I taxied the Sensei out onto our new nylon mat runway, I was pleased to see that the steering worked well when the plane is on the ground. While the nose gear would turn the Sensei quickly, I didn't feel as though it was over-sensitive.

    I pushed the throttle stick to full, and she started rolling down the runway. While I was keeping the plane rolling straight, the wheels came off the ground! It didn't leap into the air, as some high-wing planes do, but rather just started a steady, level climb toward the sky. The Sensei took off without ANY elevator input at all!

    Once up at a comfortable height, I gave the transmitter two clicks of right aileron trim, and then trimmed the elevator for level flight at half-throttle. I was completely amazed by how gentle the Sensei is in the air.

    Due to the fact that this is a trainer, I wasn't expecting any great feats for high speed, but she did move along at a decent pace - she's not a slouch by any means. Slow speed was better than I had hoped for, as she'll slow down to almost a crawl and still hang in the air!

    I decided to try some mild aerobatics with the Sensei, and I must say that I was pleasantly surprised! Loops can be made very small, or with a slight dive to gain speed, large and graceful. Aileron rolls were fairly quick, given the light weight and long wingspan. I was amazed by how well she handled stall turns - the rudder was very effective, and I had a lot of fun doing tight figure eights.

    It finally came time to land. I must say that it lands as mildly mannered as it took off. A little aileron to keep the wings level, and I cut the throttle back about 100' feet before the runway threshold. The Sensei slid right in and landed as level as could be! If you listen closely to the video, you might even hear me say, "Dang, this plane glides forever!"

    I had the opportunity to bring the Sensei to Watts over Owatonna, and I had a blast flying the plane there as well! Hobbico, one of the main sponsors for the event, had another Sensei there as well. Jim Sandquist, one of the Team Futaba pilots, was letting people fly his Sensei. Everybody that I saw fly this plane was amazed at how docile it was!

    I think that Flyzone has a real winner on their hands with the Sensei. Its good looks, easy assembly, and great flying characteristics add up to make this one sweet airplane!

    I am an advanced / experienced RC Flyer and Modeler and got this from a friend that had it for training but, the trainee happen to develop some health issues so, he sold it to me. I can not stop talking about this model and equally can not stop flying it. It is so majestic and graceful in its flying manners and during landings without any power it glides in for a very gentle landing and no bad habits whatsoever.

    I have had to replace servos on most of the foamys I have purchased. I will receive mine today and try to have it ready for our Thursday flying session. I think I will prefer the electrics to nitro planes, I have an Alpha 40. I am a beginner and need a slow aircraft to fly. I recently demolished a FMS Cessna and am tired of rebuilding it after every flight. I am hoping for the best with this one.
