    Cessna Skylane EP

    The World Models Cessna Skylane EP is a geared Speed 400 balsa-covered scale replica available from Airborne Models. The strong wood structure and tough covering give the airframe low wingloading and the capability for further power upgrades. It comes with geared speed 400 motor, propeller, and spinner.

    The Cessna Skylane EP has full house controls (ailerons, elevator, rudder, and throttle) which extend maneuvering limits and deliver scale flying. Spare parts are also available from Airborne Models.

    Key Features:

    • Scale park flyer fabricated with top quality balsa plywood and covered with genuine heat shrink covering
    • Strong wood structure and tough covering give the airframe the best load to weight ratio and capability for further power upgrades
    • Comes with geared speed 400 motor, propeller, and spinner
    • Full house controls (ailerons, elevator, rudder, and throttle) extend maneuvering limits and deliver scale flying
    • Parts including main wing, rudder, elevator and propeller
    • Replacement parts are available separately

    Cessna Skylane EP Parts
    The custom box protects the main fuselage and wing
    All the package contents are grouped by plastic wrap

    The Cessna Skylane EP comes well packaged. The individual parts are wrapped in plastic and further protected by seperated cardboard compartments in the box. The list of individual scale parts in the kit is impressive. It includes wheels, pants, front and tail gear sets, struts, cowl, windshield and side windows, propeller, spinner, motor with installed pinion gear, gearbox, sponge, pushrods, and all the hardware needed to complete the model.

    Some inner views of the fuselage reveal a quality laser-cut frame that is both strong and light.
    The battery and servo bay is pre-installed for easy installation of your selected components.
    Notice that the control rod tubes are already installed and glued in place.

    Assembly
    Once the aileron hinges are glued with thin CA, you need to route the servos using the pre-installed string.
    All the hardware is supplied in the kit including the snap-keepers and fuel line keepers. I connected the two aileron servos with a "Y" adapter.
    I used FMA PS-10 servos so I needed to glue small plywood pieces into the servo bay before mounting the servos.

    The tail of my Cessna assembled easily. I used Aileen's Tacky White glue to attached the stabilizers. There are pre-drilled holes for the control horns so be sure to mount the symetrical elevator with the pin holes on the right side of the plane. Before mounting the stabilizers to the tail, the control surfaces are attached using thin CA on the supplied hinges.

    The linkage installed easily with all the parts supplied. I used HS-55 servos for the rudder and elevator.
    Rubber keepers were supplied for both ends but I left them off the servo arm since the snap keepers had a great fit.
    Pin hole marks from the factory provided perfect placement for the control horns. The control rods were pre-installed.

    The FMA Dual Conversion M5 receiver is now compatible with Digital Servos and other super-sensitive servos. The M5 v2 is the smallest five-channel Dual Conversion receiver available today. It is designed for planes where size and weight makes a difference such as in park flyers, sailplanes and electric planes. Although designed for these planes the high reliability of the new M5 receiver makes it ideal for all planes, even up to quarter scale. The new Dual Conversion M5 v2 has increased resolution and built-in decoding technology which digitally filters the transmitter signal from noise providing “fail-safe” type protection for any standard FM system. The aircraft will "fly-through" temporary interference with the servos remaining unchanged, and, after 3 seconds of signal loss, the receiver throttle channel signals the ESC to shut down the motor, thus preventing fly-aways.

    My Cessna Skylane EP uses the new M5 v2 from FMA Direct

    Although the pinion gear was mounted on my World Models Speed 400 motor, I re-positioned it slightly and added some Locktite to the set screw.
    The gearbox attached to the motor front with two supplied screws.
    The custom frame on the Skylane EP accepted the geared motor without issue and it was held in place with only two screws but also supported several places in the plywood frame.
    I mounted my M5 v2 receiver to the side of the servo bay with servo tape.
    To route the antenna wire, I drilled a hole through the back wall,
    and glued a small piece of white tubing on the vertical stabilizer.
    The cowl must be installed before the spinner is mounted. Before the cowl can be put on, the front gear must be installed. Everything is supplied and the installation is easy. I must admit that I was surprised by the craftmanship of this model. It was much higher quality than I expected. Note that the cowl comes pre-trimmed with mounting holes on the side and plenty of air openings in the front.

    The spinner is a combination spinner and prop adapter. It uses a tiny metal rod to mount to the gearbox shaft. The rod is secured with a 3mm set screw. After mounting the cowl as far back as possible, the spinner installed nicely. I tightened the folding prop blade screws just enough so that the blades would not flop around but could still be moved with little force.

    The four side windows were all pre-trimmed and ready to glue in place. I used some tacky white glue to secure them.
    The front and rear windshields were pre-drilled as well so I simply drilled some pilot holes in the fuselage to install them.
    I ran my antenna wire out the top of the rear window.
    The gear mains installed very easy..
    The thick plastic pants are locked in place by both the molding and matching straps.
    I could now stand my
    Cessna on all 3 wheels.

    The wing installed with two screws and washers into pre-installed T-nuts in the fuselage. The kit also supplies a plastic protection piece for the top of the wing that applied using doudble-sided transparent tape.

    After installing the wing, I only had a few things left to do like adding the struts, installing my ESC, and finish applying the decals.


    My Jeti 20 Amp Microprocessor Motor Controller (JES020) was attached to the motor after first installing a Dean's Ultra connector on one end and some female motor connectors on the other end.

    The gearbox has a low reduction ratio as a 3-cell Lithium pack provided too much voltage, creating currents over 20 amps with the stock prop. I tested two different packs.


    * 2-cell, 3.1oz, Kokam 1250mAh (15C) pack, 11amps, 67w
    * 2-cell, 4.5oz, Kokam 2000mAh (15C) pack, 15amps, 110w

    I optioned for the lighter 1250mAh pack and was RTF at 22.1oz with the 2-cell pack installed. This was 4oz or 1/4lb lighter than the stock weight by using Lithium battery technology.

    The pack is shown in the position that provides the correct CG. It is secured by Velcro strips on the bottom and then wrapped with a Velcro strap.

    Here are the component weights for the Cessna Skylane EP:

    • Cessna Skylane EP w/o battery = 19.0oz
    • 2-cell 1250mAh Kokam pack = 3.1oz
    • 2-cell 2000mAh Kokam pack = 4.5oz


    Test Flying

    I flew my Cessna Skylane EP over grass on the maiden voyage as I needed to go to the flying field that day for other testing. It flew remarkably well and the geared Speed 400 motor has sufficient power for scale flying and simple loops. Since we were on grass, we hand-tossed it. The Cessna flew very stabile and was manueverable in small areas. It didn't like landing on grass as the tiny front wheel would always dig in and flop the plane over, even when touching the rear wheels first as in the photo below.

    The video of my Cessna Skylane EP used the stock geared Speed 400 motor and prop. I used a 2-cell Kokam 1250mAh Lithium pack and we could take off and land in an empty parking lot without issue. The steering is minimal on pavement with the fixed nose gear so the take-offs were short into the wind. Flight times were about 5-7 minutes depending upon aerobatics performed. The pilot for my video was Lynn Bowerman.
