    Flyzone Piper J-3 Cub

    Hobbico introduces a Ready to fly Flyzone Piper Cub. Everything is almost done for you and all you need is 8 AA batteries and 15 minutes to assemble!


    Kit Name: Hobbico Flyzone Piper J-3 Cub
    Price: $159.99 retail price
    Wingspan: 36.25"
    Motor: included 380 size brushed motor
    Battery used: Included 7 cell 8.4V 1100mah NIMH
    ESC used: Included 15Amp
    Radio equipment: Included 4 channel Tactic FM radio system and 3 Sub micro servos

    Bolting the tail in place
    Included Wrench

    The Cub arrived in a big box and everything was tied down. Once opened you see the Cub sitting there almost fully assembled! There is no much to building this one as Hobbico has done everything for you.

    The assembly begins with bolting the tail on. The Horizontal stab is put in place with a plastic hold down and 2 long bolts. The 2 tiny nuts were threaded on from the bottom and they even include the tiny wrench you need! After the stab is on the Vertical stab and rudder were then mounted using the 2 tiny machine screws, and again they even include the Phillips head screwdriver so no other tools are required.

    Stab bolted in place
    Installed radio system
    Control rod with keeper
    The 3 Sub Micro servos are already installed, one each for Elevator, Rudder and ailerons. The servos will need adjusted after hooking the control rod to the surface and this is done by loosening the screw on the E/Z connector with the included screwdriver. The receiver and speed control/motor are also installed, you only need to plug the aileron servo into the receiver.

    The control rods were attached to the surfaces and then a tiny plastic holder was pressed in place to keep them from popping off.

    Wing struts
    Included charger
    Transmitter Batteries
    After bolting the wing in place, the struts were installed next. Follow the instructions and use the correct length of screws to hold them in as they need to thread into the plastic button that is on top of the wing. My struts when installed were slightly bent as they seemed a tiny bit too long, I was informed this is so the wing can flex a tiny bit giving the proper dihedral.

    The flight battery was charged using the included charger. It plugs into a 12 volt Lighter socket so there is no easy way to charge the pack when at home unless you have a 12 volt power supply to run the included charger. It slides in under the fuse, be sure to get the plastic battery door in place correctly and that it "clicks" when installed, I lost mine on the first flight as I did not have it clicked in.

    The transmitter is a 72mhz FM radio so be sure you grab the appropriate channel pin from your pin board so you don't shoot anyone down on the same channel! The 8 AA batteries are installed in the holder then put in the radio.

    Battery in place
    That is all there was to the assembly now on to the flying!

    The CG was checked per the manual and it said it should be balanced but mine needed 1/2oz of lead in the nose to balance perfectly. I put it inside the cowl. The control throws listed in the manual call for 1/2" up and down on the Elevator and 3/8" right and left for the Rudder. I found these to work perfectly but they listed 3/16" up and down on the ailerons which did not seem to give good control response. I adjusted the throws on the Ailerons to as much as I could get, but it wasn't more than 1/4" or so as they just can't move much more.
    I tried to take off from the runway a few times and the first 2 times it ground looped on me. There is no steerable tailwheel so it can be hard to keep it tracking straight. I recommend hand launching the Cub as this worked perfectly and it fly's right out of your hands. Just hold it level and give it a good toss at a slightly higher angle than level, you do not want to throw it in a upward angle as it will stall.

    I did get a good take off from the ground in the video when the wind shifted so that it was right down the middle of the runway.

    Flying around in circuits required half throttle and loops required full throttle to get over the top. The Cub fly's pretty fast for this style plane. I flew around for about 4-5 minutes before I could tell the battery was getting low so I setup for a landing.

    The Cub glides well and landings can be a little bumpy but not too bad. If you do happen to crash yours there are replacements parts available cheaply so you can get back in the air quick.

    The Flyzone Cub is a all in one package that can go from the box to the field in less time than it takes to charge the battery. Since spare parts are available there is not the big fear of crashing you may have with other planes that require lots of building to get back in the air. The Radio is also FM 72mhz and not those 27mhz ones that are prone to interference.

    Today I have planned the maiden flight of my Cub. I’ve been out of R/C planes since 1991 so I’m hoping all goes well. I have had some recent flight time with my Dads Hobbyzone Cub and did well. It’s almost like riding a bike.......right!?As far as matching paint goes, I picked up some Testors 1169 Flat Yellow which matches pretty good. I had some shipping scratches forward of the h-stab that I touched up with the Testors and you can’t even tell they were there. I painted the exposed foam edges of the stabs too. Looks a lot better! I also replaced the small stock main gear wheels with DU-BRO 1-¾” Super Lite Wheels. They look a lot more realistic on the Cub and should make landings in the grass at the park a lot easier.
