Extreme Flight has been a leader in the Radio Control ARF market for some time. The build and flight quality of their planes has propelled them to become a class leader. Adding to their already successful new line of high quality ARF balsa airplanes, Extreme Flight has introduced a new pattern/aerobatic airplane to their fleet - The 48 Vanquish. The Vanquish is modeled after the beautiful 2 meter pattern planes which dominate the FAI pattern scene the world over. Extensive testing and thoughtful design have yielded a model which can be transported in any small car, yet flies like its much larger siblings.
The 48 Vanquish has many innovative ideas incorporated into its design including removable wings which mount on a carbon fiber wing tube and an upper hatch which is mounted using strong magnets and a spring loaded mechanical latch. This is an aerobatic airplane that excels in precision flight but can also fly 3D maneuvers as well. In fact, it flies pattern so well, some pattern competitors are using it as a practice plane.
The Vanquish arrived in excellent condition due to its good packaging. The main kit box was overboxed with a second stronger outer box. It was neatly packed, and each part was placed in its own protective plastic bag, securely held in the box with packing tape. Cardboard dividers help to insure that no one piece rubs or scratches the other parts of the airplane. I ordered the Super Combo, so the shipping box also contained the Airboss Elite 45 amp speed control and the Torque motor for the Vanquish. ·
The Vanquish comes with a very complete manual that is easy to follow and understand. Included in the manual are guidelines for setup, flying and handling of the model. Following the manual, assembly goes quickly and without any snags.
The difference between the Vanquish and other ARFs on the market begins with its pattern designed wing. The wing design uses a thin airfoil compared to most sport and 3D airplanes. This wing gives it precise handling and razor sharp snaps, but does not endow the airplane with any bad habits.
Installing the ailerons on the Vanquish is a simple task. The Ailerons and wings come pre slotted for the included CA Hinges. When you install the ailerons, check the alignment of the hinge slots by viewing the aileron from the trailing edge. Make sure that the hingeline of the wing and the aileron match up correctly. The left wing on my model was slightly off, but was easily corrected by re-slotting the aileron and wing by one hinge width to the side of the original location. I used Futaba S3102s on all control surfaces so I had to modify the servo mounts in the wings with my dremel tool after removing the covering from the servo mount hole. I tested an HS65 and that servo simply dropped right into the servo bays. The hardware included in the kit is simple to install and robust.
Installing the tail is a simple affair. I used a hot soldering iron to carefully remove the covering from the fuselage sides. Then I test fit everything to insure that the covering was removed from all gluing surfaces. Following the instructions provided in the manual, I slid in the elevator followed by the horizontal stabilizer. After sliding the elevator hinges into place, I lined the elevator/horizontal stab assembly in the fuse and glued it in place with medium CA. No sanding or adjustments were necessary as the Vanquish was perfectly straight out of the box. The notch at the leading edge of the horizontal stab was very helpful in aligning the assembly. I decided to epoxy the vertical stabilizer in my Vanquish, and again no adjustments or sanding was necessary. I used Epoxy to secure the control horns in the surfaces after roughing their mount areas slightly with rough sandpaper.
Installing the elevator servo was a snap after adding an 18 extension to the servo itself and removing the covering from the mount hole with a soldering iron. The included hardware was easy to install and simple to adjust.
I installed the rudder servo in the fuse and threaded the pull-pull cable through the fuse. I found it easiest to secure the cable to the servo first and then secure it at the control horn end.
The Vanquish uses a mixture of thin plywood and laser cut balsa to provide a strong but lightweight structure. Inspecting the glue joints in my Vanquish revealed not a single glue joint which needed reinforcement, and my subsequent flights backed this observation up.
The landing gear mount is strong and needs no reinforcement. Lightweight aluminum landing gear is provided for the Vanquish and proved to be more than adequate for bumpy grass field landings. As stock, my Vanquish landing gear showed a significant amount of toe-out at the wheels. I re-drilled the innermost hole on the landing gear to allow the wheels to align in a more straightforward fashion. Ive flown the airplane with the landing gear in both positions and both are fine.
Following the instructions, the motor box was easy to install. However prior to installing the motor box on the front of the plane, I elected to install blind-nuts in the rear of the firewall to ease future maintenance. This took only a moment as the firewall is pre drilled for the Torque motor thus removing any guesswork during the installation. From my experience flying several friends Vanquishes, I decided to install my motor with right thrust. I added (2) #4 washers under the left side motor mount tabs during installation to give the correct amount of right thrust. I mounted the ESC to the bottom of the motor box with some Velcro and a zip tie. This location put the ESC right in front of one of the cool air inlets in the cowling for better cooling. After mounting the motor and ESC, I taped the cowling in place with masking tape. I used the spinner and the paint lines to aid in getting the cowling on straight. Once straight, I drilled the cowling and fuselage to accept the mounting screws provided in the kit.
The Vanquish is an extremely quick build and can be completed in a couple of relaxed evenings worth of work. The quality of materials, construction, and the level of pre-fabrication keep the build simple and almost error proof.
My EF 48 Vanquish came in at 46 oz. ready-to-fly. While the finished weight came out slightly more than I hoped, I was sure it would still fly extremely well given that it still maintained a fairly light wing loading (15.24 oz/sq. ft.) on 425 sq. in. of wing area.
Control Throw Setup
|Control throws were set per the instructions manual:|
|Low Rates Up||Low Rates Down||High Rates Up||High Rates Down|
|Elevator||10 degrees||10 degrees||max. throws||max. throws|
|Aileron||20 degrees||20 degrees||max. throws||max. throws|
|Low Rates Left||Low Rates Right||High Rates Left||High Rates Right|
|Rudder||15 degrees||15 degrees||max. throws||max. throws|
The EF 48 Vanquish tracks very well on the ground and offers the pilot no bad tendencies or additional work load. The main wheels have a slight tow-in while on the ground, and I am sure this contributes to improving the ground roll of the Vanquish . Takeoffs can be done with as little as 1/2 power. Very little rudder is needed during the short takeoff roll to maintain a straight track.
Once in the air, the Vanquish is very light on the wing and can be comfortably flown at very slow speeds. Stalls offer no surprises and simply result in a slight drop of the nose once effective lift is lost. There is no drop of a wing tip during the stall. Recovery is simply a matter of reducing elevator input and applying throttle. Like any good pattern plane, the Vanquish tracks extremely well in the air and goes exactly where you command.
Landing the Vanquish is as straightforward as I have seen on a plane of this size. Align it on a nice descending path with a slight amount of power until a few feet above the runway, and you will be rewarded with nice three point landing every time.
The EF49" Vanquish was made for pattern flying. Flip the switch to high/3D rates and the Vanquish will not disappoint. I found that the Vanquish could do most pattern maneuvers with ease. Knife edge flight with the Vanquish is very stable, and I found that there was a minimal coupling which was easily mixed out. Rolls are fairly axial and can be extremely fast when set up for maximum deflection. I only needed a small amount of aileron differential to make them completely axial. The Vanquish does snaps extremely well with its long tail moment
The Vanquish does quite well flying precision maneuvers- as it should with its clear pattern intentions. Four point rolls, slow rolls, loops were all very nice when set up on low rates and flown at moderate speeds. Inverted flight required only slight down elevator, but further CG trimming eliminated much of this.
|EF 48 Vanquish Precision Report Card|
|Rolls||A-||The Vanquish does these quite nicely. There is lots of throw from the ailerons available to get these to start and stop quickly.|
|Level Flight||A||This is very stable. No tracking issues.|
|Snaps||A+||Crisp and precise!|
|Stall Turns||B||Needed a more rudder throw to initiate and correct.|
|Rolling Circles||A +||Extremely smooth and easy to perform.|
|Knife Edge||A-||Excellent with minimal coupling.|
|Flat-Spins||B+||Easy to initiate, but easier with high rates.|
I would say that the EF 48" Vanquish is NOT for a beginner. The Vanquish does not have the self-leveling capabilities of most trainers and would make for a very nice 2nd or 3rd low wing airplane.
The EF 48" Vanquish is a terrific looking and great flying precision airplane which can 3D as well. The supplied power package provided more than enough power for the Vanquish without compromising the integrity of the airframe. The included hardware that comes with the kit is top notch. I look forward to flying more of my EF Vanquish this year as it always draws a crowd any time it's at the field.

Nice review!! The Vanquish appears to be a very smooth flyer and you did extremely well putting it through its paces.
Same question as txfly, what prop were you using in the video and how many amps and watts was this setup pulling?
How does it 3D??

Thanks for a great review, this will be my next Extreme Flight plane--I already have the electronics for it. I just need the airframe.

Totally agree, great review, I maidened my vanquish a few days ago and whoever gets one of these models will not be dissapointed, this is simply an awesome model, whether it be 3D or Pattern, it perfroms both with ease and suprisingly feels like a much bigger plane than what it actually is, nice job!
Quick vid of my vanquish flying 3D if anyone is interested:

Excellent review Jeremy! The Vanquish looks like it's on rails
And I like the music, who is that wringin' out the guitar? Sounds very much like Eric Johnson or Joe Satriani.
