    ParkZone Habu EDF BNF

    ParkZone® has entered the mainstream EDF market in their usual Bind-N-Fly style with the new Habu EDF Jet which is a full-throttle thriller capable of very high speeds and full-house aerobatics. Powered by E-flite's BL15 3200Kv brushless ducted fan motor mated to an E-flite Delta-V 15 ducted fan, the potent combination produces enough thrust for outstanding climb performance and thrilling high-speed passes. When it comes time to throttle back and enter the pattern, the Habus wide flight envelope and forgiving slow-speed handling was designed with the intermediate pilot in mind. Anyone used to flying faster sport planes can perform picture-perfect, nose-high touch downs and takeoffs with the Habu.

    Getting this Bind-N-Fly version airborne is about as simple as it gets. Just attach the wing and tail, charge the battery, and bind the receiver to your full range DSM2 transmitter. After a quick check of the control surfaces, you're flying!

    ParkZone has delivered their fastest plane yet, so if you have intermediate to advanced flying skills, and you are looking for some high-speed jet thrills, the Habu EDF Jet is just what youre looking for!

    BNF Contents :

    The ParkZone Habu EDF BNF comes well packaged and protected. The Bind-N-Fly version includes everything you need except for a full range Spektrum DSM2 aircraft transmitter. The one-piece wing has the aileron servos and linkage pre-installed and molded servo covers to protect the linkage on landings. The gear mains receptacles are pre-installed so they just press in place, if needed.

    The tail assembly comes ready to attach to the fuselage with elevator and rudder servos pre-installed. The vertical stabilizer presses through the tail into the fuselage. The cockpit/canopy uses two prongs in front for automatic alignment and strong magnets to stay in place. The optional landing gear with steerable nose wheel can be used for pavement or hard surface take-offs.

    An E-flite 4-cell, 14.8V, 3200mAh, 30C Li-Po battery is included along with the ParkZone 3s-4s, DC, Li-Po, Balancing Charger. Simply select the cell count, set the current dial, and press the start button for a safe, balanced charge.

    The 36-page manual is loaded with photos and step-by-step instructions to help you ready the Habu for flight. It covers both BNF and PNP versions. The details in the manual were very helpful to complete some of the assembly. The E-flite 60A Pro Switch-Mode Brushless ESC manual and BL15 3200Kv motor manual are also included. No programming changes are needed to ready to Habu for flight.

    A closer look at the fuselage reveals more of the pre-assembly that ParkZone® has made famous. The Z-Foam design is very tough and can be repaired with regular CA and kicker. The E-flite 60A Switch-Mode ESC, AR500 DSM2 5-channel sport receiver, battery bay, and E-flite Delta-V 15 ducted fan unit are all pre-installed.

    The fuselage is pre-painted with all the decals applied. Servo extensions are pre-routed for easy hook-up.

    Assembly:

    The wing is attached to the fuselage after first connecting the aileron leads to the pre-installed Y-harness. I also added a tie-wrap around the motor wires before attaching the wing to prevent any movement inside the duct during flight. The two locator pins align the rear of the wing and the single mounting screw aligns the front while securing it to the fuselage.

    The tail is assembled in a similar fashion as you plug in the servo leads before pressing it in place. Note that the brown wires on the elevator and rudder servo leads are to the left when viewed from the rear.

    I used the larger black screws to secure the horizontal stabilizer to the fuselage. The vertical fin is then surrounded by plastic mounting plates which are secured with 5 black self-tapping screws. The rudder pushrod connects to the second outermost servo arm hole and the outermost rudder control horn hole.

    The tail cone is pressed into place and secured with the supplied tape strips.

    The Habu was designed to provide a choice to fly with or without landing gear. Flying without the gear reduces drag and provides the highest speed. The Habu is easily hand-launched and can land on its belly on grass or snow. Two nose wheel plates are provided; one with a servo to steer the nose wheel and another just to cover the opening while allowing some air flow for cooling. Also included are two skids for belly landing. One is placed just behind the nose wheel plate (as shown on right) and the other is placed just in front of the exhaust nozzle.

    Final Assembly: After binding the receiver to your transmitter, check the control surface directions, travel amount, and CG per the manual directions. The CG is located 4" from the leading edge at the root of the wing. My battery pack fit perfectly into the recessed tray and is strapped in place. I had no issues with the CG.

    I set the throws on my Spektrum DX7 transmitter using the high and low rates recommended on page 29 of the manual. I also added 30% expo to the elevator and aileron settings. I usually don't add any expo on the rudder.

    Test Flying:

    My ParkZone Habu EDF BNF was Ready-To-Fly in no time at all. It weighed about 46oz (2.88lbs) and the power level felt very strong. I measured the power level at 52 amps for about 750 watts which provides a very capable 260w/lb. The included 4-cell, 3200mAh, 30C, Li-Po battery seemed to be very good quality.

    For our ParkZone Habu flight testing, the weather was cloudy and a cool 33 degrees F outside with light winds from 5mph to 10mph and a layer of snow on the ground. Not great conditions for test flying a fast grey colored model but it flew well with plenty of power and the yellow trim scheme allowed us to keep our orientation. Team JR's, Devin McGrath, put the Habu through a series of maneuvers to test its agility and power.

    Flight times were quite long and lasted a good 8 to 10 minutes. We were surprised at the top-end speed of the Habu as it is quite quick. However, we expected it to be agile and stable and the Habu did not disappoint us. The stock power level is very strong and we could climb until the plane started blending into the grey sky. My hand-launch seemed easy and very little trim was needed on the maiden flight.

    We discovered that the Habu does hold speed very nicely. When belly landing in the snow, the glide across the park went further than expected and came to rest just before reaching a side street. The slide across the snow caused no scratch marks. Although it was difficult to slow down on the snow, because it would glide a long way, the plane landed very predictably.


    Summary:

    The ParkZone Habu EDF Jet was designed to be relatively easy to fly so that most pilots with intermediate to advanced experience can handle it comfortably. We found the Habu to be a very efficient and stable design. After a quick assembly, and only a few trim clicks after the toss, we were ready to have some fun!

    The Habu flies inverted with a small amount of down elevator and it also glides very well. Both the vertical climb and slower flight performance were very good using the stock 4s LiPo pack. I feel that this jet is a good value because of the overall construction quality and the wide speed envelope that appeals to many pilots.

    Although the E-flite 60A Switch-Mode BEC brushless ESC can handle up to a 6-cell LiPo pack, the current draw on the Habu setup using a 5s pack is more than 60-amps so it is not recommended. When using a 5s LiPo pack, the current draw is around 70-amps so you'll need to upgrade your Habu with an ESC like the new Phoenix ICE 75 from Castle Creations.

    When it comes to speed, the Habu is not your usual ParkZone model. Although it flies nice and stable at a wide range of speeds, and stalls predictably like other ParkZone designs, it is many times faster than their other models! ParkZone has gained a good reputation for producing planes that fly well right out of the box and the Habu fits that reputation perfectly.

    Hi Greg Thanks for the review it made me go out and buy a Habu. I have question for you though. I like to take off grass at my farm.I cut the runway down to 1.5 inches.It takes forever to get off the ground at least 800 feet plus.If I raised up the nose wheel to increase the wing incedence do you think they may work better? Regards Adrian
    Posted by: Greg Covey on 06/13/2010
    Hi Adrian, it is possible that raising the nose will help. Increasing the wheel size and using Dubro lightweight rubber wheels will also help instead of using softer, smaller foam wheels. At a local event last weekend, a guy told me that his Habu takes off grass without the gear on so maybe it will even slide better on the right grass conditions. I hand toss mine and belly land on grass. Still using the stock 4s setup. Good luck!
    Posted by: AWINSHIP on 06/17/2010
    GREG Do you hand toss yours by yourself? If so where do you grag it and how hard do throw it?I might just try doing a bellt takeoff but it seems strange that this will work. If I get up enough nerve to try it this weekend I will let you know how it works. On a different plane I bought a Dassault alpha from HobbyKing should be here next week,looking forward to see how this one flies. Regards Adrian

    I hold it just in front of the wings under the fuselage and give it a medium to strong toss. As you can see on the maiden flight video, it works fine even if it is out of trim since it has plenty of power. Good luck!
