    V-Pro MIG-15 EDF ARF

    The V-Pro Mig-15 EDF Jet ARF from Advantage Hobby boasts speeds of over 120mph! The painted fiberglass fuselage comes with the 69mm fan unit and motor pre-installed. The sheeted wing and tail halves are pre-covered, making assembly time quick!

    The model comes with a 7-page construction guide, decals, linkages, hardware, Tamazo DF-69 Fan Unit with mounted brushless motor, and a "sling-shot" starter set.

    Specifications:

    • Length: 33.3"
    • Wingspan: 32.9"
    • Wingarea: 222 sq. in.
    • Flying Weight: 39 - 42 oz.

    Key Features:

    • ARF Construction
    • Painted Fiberglass Fuselage
    • Film Covered Built-up Wing
    • Clear Canopy


    ARF Contents :

    The 33" long, pre-painted, single-piece fiberglass fuselage also contains the vertical stabilizer. The sheeted wing halves were rock-solid and perfectly covered. The ARF jet package comes with a minimum amount of parts.  And if spare parts are needed, they are available upon request.  Advantage Hobby will part out kits to help their customers.

    The model comes with a 7-page construction guide, decals, and a "sling-shot" starter set.

    Fuselage Close-up:

    A closer look at the fuselage reveals a top hatch to access the battery and "cheater" holes to allow more air into the ducted fan unit.

    A bottom hatch reveals the quality of the motor mount. The EDF unit comes well secured to the fuselage by four screws and a round bulkhead.

    MIG-15 Assembly:

    The assembly begins with the aileron servo installation. I used Futaba S3114 High Torque Micro Servos and a 12" (300mm) Futaba AEC26 C-26 Extension.

    Instead of mounting the servo with double-sided servo tape, I used 5-minute epoxy after first roughing the joining surfaces with sandpaper. The control horn was also glued to the aileron using epoxy before connecting the linkage. A straight metal rod is supplied in the kit so you need to add a "Z" bend at one end.

    The result is a nice streamlined aileron control. The rod was connected to the highest hole on the clevis for minimal swing and maximum resolution since only +- 5mm of travel is needed.

    The quality of this Mig-15 model is really seen when mounting the wing halves. Two carbon tubes are passed through the fuselage and glued in place with epoxy to help support the wings. After first roughing up the gel coat on the fuselage area where the wings meet, the two halves are epoxied in place.

    The final step of the wing assembly was to CA glue the fence pieces into the pre-drilled holes. Another perfect fit for this model.

    I decided to glue my horizontal stabs in place with epoxy. So far, I haven't had any fit problems with my model. The Futaba S3114 servo was a bit small for the mount so I added a section of a toothpick to help hold it in place. I used medium CA to hold the servo and wood blocks to the mount.

    After test fitting the horizontal stabilizers, I glued the servo and mount to the inner fiberglass wall with 5-minute epoxy so I could hold it in proper alignment until it set. I tested the movement once the epoxy dried and then secured the horizontal stabs in place with a small amount of epoxy on the two wing joiner rods.

    After the final movement testing of the horizontal stab, with the radio system, I secured the round tail hatch cover with medium CA.

    Before sealing up the fuselage bottom, I recommend adding some thin Mylar ducting from the EDF unit to the tail opening. This can be made from any thin plastic sheet like those seen on school report folders. The ducting smoothes the air flow over the rear former. It increases the efficiency and power level of the ducted fan system.

    I used the supplied clear tape to hold the Mylar ducting to the EDF unit and to keep the shape against the fuselage wall in the rear opening. The bottom hatch was then sealed by tape on all four sides.

    Canopy:

    After applying the cockpit decal, the canopy was glued in place using Bond 527 Multi-Purpose Cement.

    Scale Air Intake:

    The scale air intake separator was first cut to fit and then epoxied in the nose. The intake separator is designed to make a smooth part in the air so it has little effect on efficiency.

    It was needed in the full scale jet to route the air flow around the pilot and is a trademark look for the MIG. A larger R/C model or a less scale version would not need the cheater holes. They are a trade-off of this small scale size.

    Scale Decals:

    The scale decals can be cut to shape and installed per the photos in the manual. I used masking tape to align the individual numbers for application.

    Power System:

    The power system was completed with the E-flite (EFLA1060) 60-amp Pro Brushless ESC that has a switching BEC regulator which allows you to operate up to 7 analog or 6 digital standard-sized servos on any recommended input voltage. No external regulator is needed with the 4-cell LiPo pack. The pre-installed E-flite ESC motor connectors fit the pre-installed Tamazo motor connectors perfectly. It was a simple plug and play solution with no programming needed.

    The Flightpower (EVO2537004S) 25C 4-cell 3700mAh LiPo Pack provides a perfect balance of 70mm from the trailing edge at 13oz. The pack can deliver up to 90-amps continuous, if needed, so the 42-amp demand will not stress it even if the entire flight is at full throttle. The pack is secured with Velcro on the entire bottom and two strap pieces that were epoxied into the plywood tray slots without extending into the air chamber below. Do not block the air flow underneath by feeding the strap around the tray.

    The components fit snuggly under the canopy. Mating air holes were cut into the front and back of the canopy to match those in the battery compartment.

    Ready-To-Fly!

    The MIG-15 was Ready-To-Fly at 46.5oz (2.9lbs) including the 13oz FlightPower pack. I measured 600 watts at 42-amps for a power level of 207w/lb. The last step was to glue the dummy antenna with epoxy in the top side of the canopy.


    Test Flying

    We finally had an opportunity to test the MIG-15 with some sunshine. It flew beautifully with the recommended throws in the manual and the supplied bungee launcher work perfect every time.

    I pulled the bungee back as far as I could and let the jet go when I heard the motor was up to speed. We used full 7mm up elevator on the launch and then released the elevator as the jet started to climb. The key to a successful bungee launch is to get as low as possible to the ground and pull the cord back just short of all the way. This technique can be seen on the video.

    The Mig-15 flew fantastic! It rolled nicely and flew inverted. It does land at a quick pace until you get some experience with it so a long field is needed. We used about 400' on our first landing but could later land in about 300'.

    The MIG-15 has no bad habits and can land relatively slow for a high speed jet. My CG was a bit nose heavy as we required about half elevator stick when flying inverted. Although the building was easy, I would recommend this model to the intermediate to advanced level pilot. The MIG-15 flies great but it can really move out! When the sky is grey, the belly of the MIG-15 literally disappears. We had a blast with this model and love how it looks on the ground and in the sky.

    Summary

    The V-Pro Mig-15 EDF Jet ARF from Advantage Hobby comes with a painted fiberglass fuselage and the 69mm motor/fan unit pre-installed. The sheeted wing and tail halves are also pre-covered, making assembly time quick and easy!

    Using a better battery like my FlightPower 25C 4-cell 3700mAh pack not only provides a stronger flight than the recommended 2200mAh Tahmazo LiPo pack but it will last for many more cycles because it is not getting stressed. The heavier weight of the 3700mAh pack also balances the MIG-15 near perfect!

    The E-flite (EFLA1060) 60-amp Pro Brushless ESC that has a switching BEC regulator which allows you to operate up to 7 analog or 6 digital standard-sized servos on any recommended input voltage. No external regulator is needed with the 4-cell LiPo pack. The pre-installed E-flite ESC motor connectors fit the pre-installed Tamazo motor connectors perfectly. It was a simple plug and play solution with no programming needed.

    The MIG-15 was Ready-To-Fly at 46.5oz (2.9lbs) including the 13oz FlightPower pack. The power system measured 600 watts at 42-amps for a power level of 207w/lb.

    Although the Mig-15 flies fantastic, I would only recommend this model to the intermediate to advanced level pilot because it really moves out and can literally disappear in a grey sky.

    Hi just want to let you know we have the L39 and it flies just as good. We took the wing tip tanks off and put the winglets on like the real reno racer uses. You can see pictures of the real L39 at warbirds of Delaware web site.

    Oh man, that's nice Greg! Nice to see a smaller EDF that isn't foam, is nicely put together and is capable of impressive speed out of the box.

    ive read this plane can be hand launched, has any one here done it yet? dont care for the bungee, too many nightmare tales ive read about them.
