    The SuperFly-E utilizes a delta wing configuration like its glow-powered brother, the SuperFly Nitro, but the airfoil and control surfaces are different allowing for a much lighter airframe. When combined with the recommended equipment, the SuperFly-E will cruise around like a park flyer, but open the throttle and it will do just about every move in the book. Both big and little inside/outside loops can be performed from level flight, flat spins, fast rolls, slow rolls, steep vertical climbs and best of all... it is extremely tough so when you do have the occasional hard landing or impact it will usually just bounce and be just fine!



    Kit Name: Superfly-Electric
    Manufacturer: SuperFly R/C
    Price: $69.95
    Wingspan: 30 inches
    Wing Area: 420 square inches
    Length: 22 inches
    RTF weight: 12 - 14 ounces
    Motor Controller: GWS 370-B gear drive w/spinner
    Batteries: 2-cell, 3.4oz, Kokam 2100 Block
    Prop Used: 8x6 slow fly prop


    Parts Included in the Kit
    Additional Items Needed
    (2) EPP wing halves
    (2) EPP vertical stabilizers
    canopy (made from leftover foam)
    (2) Depron foam elevons
    (1) GWS 370-B gear drive w/spinner
    (1) 8x6 slow fly prop
    (2) Dubro control horns
    (2) elevon pushrods
    (1) plastic engine mount plate
    (2) heavy zip ties
    CA and kicker, 5 min epoxy and Shoo Goo
    duct tape (Walmart has different colors)
    clear or colored packing tape
    paint
    (1) GWS R4P Micro receiver (1000 foot range, don?t go thermal hunting too high)
    (2) GWS Pico or Naro servos (or equivalent)
    Connectors of your choice for ESC, motor and batteries.
    8 amp ESC (electric speed control)
    8 cell 720 mAh NiMH flight pack
    battery charger
    Radio with mixing for elevons
    flight support equipment


    Note that an equivalent to Shoo Goo called All Purpose Weld is available at most Walmarts, hardware stores, and some hobby shops. The servos should weigh 0.3oz or less and the flight pack needs to weigh 4oz maximum. Building this plane as light as possible makes a real difference in performance.

    I took some liberties with the order of assembly when building my SuperFly wing. This allowed me to deviated in a few areas since I knew that I would be using a 2-cell, Kokam 2100 Block from Radical RC. I also used 5-minute epoxy for gluing the EPP wing halves together along with the motor plate, and when mounting the stabilizers.

    To ease the elevon taping procedure, I installed the elevons before gluing on the stabilizers. By using the 2-cell, 2100 Block Lithium pack, I felt that making the EPP canopy was not necessary.

    The wing cores are removed from the base and rubbed together to remove slag before gluing.


    The black plastic motor mounting plate is glued along with the wing halves after first cutting a 1"x3" rectangle into the nose.

    The two EPP stabilizers are traced and then cut from the thin sheet removed from between the wing cores.

     

    Most small electric motors are designed to rotate Counter-Clockwise (facing Pinion gear end). The brushes are positioned so that they encounter the least resistance when the armature is spinning Counter-Clockwise and motors are typically timed to be more powerful and efficient in that direction as well. Using a two gear drive causes the propeller shaft to rotate opposite of the motor shaft, which is the wrong direction for the prop. Therefore the factory motor connections must be wired in reverse so the resulting propeller shaft rotation is correct.

    The GWS motor and drive assembly comes with the negative lead connected to the side of the end bell with the small red dot (positive terminal), causing the motor to run backwards from the direction originally intended. This causes rapid brush wear and improper timing, resulting in noticeably less thrust and reduced motor life. This setup can be improved greatly with a simple modification which will allow the motor to turn in its natural CCW direction by rotating the drive shaft 180°.

    When using a GWS 8x6 prop, the RPMs increased after performing the modification from 5700 to 6900 using the 4.43:1 "B" gearbox on and 8-cell pack of 700mAh AAA batteries.

    For further details on the GWS EPS-300C (or EPS-350C) geardrive hop-up, download the conversion in PDF from the SupeFly R/C site here.

    The motor is mounted using 2 tywraps (supplied) after drilling 4 holes into the mounting plate.



    Right:
    The elevons are reinforced under the control horns from pieces cut off of the outer ends.

    .

    The HS-55 servos are mounted 4" apart and 4" forward from the trailing edge. The plane balanced perfectly (as shown) with the 2-cell Lithium pack against the servo front wall.

    The SuperFly-E was ready-to-fly at 12.7oz using the 2-cell Kokam 2100 Block.

    My SuperFly-E was ready to fly at 12.7oz using the 2-cell, 3.4oz, Kokam 2100 Block. The 2100 Block is equivalent to a 2s2p pack of Kokam 1020mAh cells but the pack shape is different. Either pack can deliver 7amps continuous current and about 14amps for short bursts.

    My GWS 8x6 prop drew about 6amps and the 9x7 prop drew about 8amps.

    When hand launching, do not hold the plane by the vertical stab, but, instead, hold the plane by the leading edge or canopy, and give it a gentle under hand toss out and away.


    A gentle forward toss starts the SuperFly on its maiden voyage.
    The SuperFly slows up nicely for low-level parkflying.
    The delta wing can hover and float in mild or breezy wind conditions.

     

     

    I have owned a good variety of wings and when I first got the SuperFly kit for review, i'll admit that I wasn't very enthusiastic about "yet another wing" design. Additionally, I thought that mounting the prop in the front was a recipe for disaster. Fortunately, I gave the design a fair chance and I was simply amazed at how it performs!

    The SuperFly is a delta wing that needs very little energy to stay airborne. The dynamic range of flight in mild to windy conditions had me raising an eyebrow more than once. It loops, rolls, and flies inverted, fast or slow all very well. It can turn on a dime at low speeds only 5' off the deck. I set up an exponential -50% for both channels to get wild throws on the outside of my sticks and docile control near the center.

    This design really does it all with just an inexpensive GWS EPS-300C or 350C power system. My 2100 Block provided a good 15 minute flight of mixed aerobatics and cruising around.

    My hat goes off to designer David Halko because the SuperFly has become my new favorite wing to fly at work. Oh, did I mention that it is quiet too!
