    Bullit ARF - High Speed Delta Wing

    The new "Bullit" ARF from Hobby Lobby is a high-speed delta wing design. The Bullit has a 33" wingspan and is 27" long with a flying weight around 36oz. This is a glow-to-electric conversion that is easy to accomplish using the recommended components. The wing is easy to hand launch as there are finger grips built into the bottom. When powered by the recommend components, this delta wing has a broad speed range and is capable of flying slowly with light and easy landins. Open up the throttle and the Bullit lives up to its name! The plane is not difficult to fly but due to its high speed it is not for the novice.

    Assembly can be accomplished in an evening and a transmitter with end point adjustments and exponential is recommended. For 3 channels with elevon mixing: Aileron, Elevator and Throttle.

    The components recommended by Hobby Lobby for a successful electric conversion are as follows:

    • PM282008 AXI 2820/08 OUTRUNNER Brushless Motor
    • PM282002 Radial Mount for 2820/2826 Brushless Motors
    • JESAP70W Jeti Advance PLUS 70 Amp Brushless Controller with Program Card
    • PQ37003 "Twenty" 3 Cell 3700 mAh 11.1V Li-Poly Pack
    • HLAN3422 AeroNaut 9x6.5 "Classic" Carbon Prop Blades
    • HLAN5140 AeroNaut 40mm Spinner
    • HLAN4222 42mm Middlepart Yoke
    • HLAN241 1/4" Prop Shaft Adapter
    • TM2039AP Accessory Pack for Bullit Delta Wing
    • RCD120 Hitec Electron 6 Receiver
    • Two - HTS085MG Hitec HS-85 Metal Gear Servos

    A Closer Look

    The Bullit comes beautifully pre-built and covered with servo locations and battery box hatch pre-done. There are few components so the assembly is quick and the manual is really just a foldout assembly drawing.

    Motor Installation

    The first step of the assembly is to attach the Radial Mount Set to the AXI motor and then solder on the mating connectors that come with the Jeti ESC. I also soldered the Dean's Ultra connectors onto the ESC and battery pack. All the connectors come with pre-cut shrink sleeving to cover the solder joint area.

    When mounting the motor, you need to first drill the four holes for the T-nuts and then set them into the wood behind the firewall. This is done by inserting the long #10 screw through the hole and threading the T-nut all the way until you can tighten down the screw to draw it into the wood.

    Once the T-nuts are set, it is an easy assembly to mount the AXI motor using the spacers, washers, and screws. Although the diagram calls for a 1.5 degree right thrust setting, I decided to keep the thrustline 0-0 for the maiden flight.


    The ESC wires were pushed through the slot from inside the hatch and then attached to the motor wires to test rotation direction before taping the connections and pulling them back inside.

    The battery pack and ESC fit snuggly inside the bay. I decided not to mount the On/Off switch and just leave it loose inside.

    The hatch cover is held in place with two screws. After drilling the proper size holes and mounting the cover, I removed the cover and dripped some thin CA inside the holes. The CA should be left to dry for an hour or so to soak into the wood and harden the surrounding area.

    When installing the Aero-naut folding carbon CAM prop, I realized where the spare brass bushing needed to go. It was required to properly center the hub onto the motor shaft. The stock adapter washer did not fit properly with the supplied spinner so I substituted a smaller metric washer.




    Each elevon uses three pinned hinges that I glued into place using 5-minute epoxy. Before gluing the hinges, I roughed the surface with sandpaper to allow the epoxy to stick better. I also test fit the elevons and hinges first so that I could mark the spots for easier placement when gluing. Be sure to leave a small gap at each end so the elevon won't hit the stabilizing fins.

    The first step in mounting the servos is to cut away three sections of covering over the servo bays and main hatch area. I then centered the servos electronically and enable the correct elevon feature in my transmitter to position the servos for proper swing. On a wing like this, both elevons go up for up, and both go down for down. To turn right, the right elevon goes up and the left elevon goes down when viewed from the rear of the wing. Left turns are the opposite.

    I didn't really like the servo anchors that came with the model and I had no intension of making the servos removable so I simply epoxied the servo to a 3/8" block inside the bay. To help the epoxy stick, I sanded the bottom side of the servo case.

    The control horns were positioned and a small wedge was cut into the elevon about 1/8"-1/4" deep. The control horns were then epoxied in place. After making a "Z" bend in the control rod, the excess was cut off. I applied some Loctite to the screw that secured the control rod to the clevis to keep it from rocking in place. On high speed models like the Bullit, it is important to eliminate any slop in the linkage.

    Servo Bay Covers:

    Lastly, the servo bays were covered with the white plastic covers. The covers needed to be cut from the molded piece and then taped in place to reduce drag from the servo bays and linkages.

    Charging & Balancing:

    The PolyQuest pack was charge/balanced using the new Cellpro 4s charger and Cellpro to ThunderPower or PolyQuest Adapter.

    Ready To Fly:

    My Bullit wing was Ready-To-Fly at 36oz (2-1/4 lbs) using
    the 10.5oz PolyQuest 3700mAh pack.


    Test Flying

    Bullit Maiden Flight Test

    The Bullit maiden flight was a success! Since I forgot to cut out the finger holes on the bottom, it required a second person to launch. It flew very fast and stabile but could slow down when landing or for a few camera shots. Flight times were about 10 minutes and we had no issues with it except for the ESC getting a bit hot. I will look into adding some cooling channels to the inside compartment.

    The pilot for the Bullit maiden flight was Devin McGrath.

    The Bullit is a sturdy covered-balsa design that flies very stabile. The winglet "ears" provide both stabilization and orientation in flight. The finger grips on the bottom allow the pilot to launch the Bullit in one hand. After the maiden flight video, it was easier to launch with the finger grips and it was trimmed out.

    The battery only get warm but the ESC was a bit hot so I will be adding a cooling vent into the inner compartment. The electric conversion was easily installed and the folding prop works great for landings.

    The Bullit has a broad range of speed which is typical for a delta wing design. For a high-speed fix, or just a break from the foam designs, the Bullit may be just what you were looking for!
