Test review
model: | Eurofighter 2000 |
manufacturer: | Carson Modellsport |
wingspan: | 650 mm |
length: | 950 mm |
weight empty: | 550 g |
weight flight: | 737 g |
edf units: | 2 * 56mm (Hyperflow) |
material | EPP |
type | ARF |
included | plane, 2 servos, 2 edf, 2 brushless motors, 2 brushless-controller 18A |
thrust: | 700g bei 11Volt 32 Amps 32.000 rev/min |
First impression:
That is quite a big box which holds the plane. Respectfully 100cm*68cm*15cm measures the package. After opening one finds a really almost-ready to fly model. The model is securely fixed in the box for transportation, the cabin, rudder and manual are fixed with tape inside the box.
Where are the small parts?
The usual bag with small parts is missing, no wonder, all the parts are already installed. That apllies to the servos with linkages as well as the ducted fan unit with motors, controllers, cables and plugs, even the magnets for holding down the cabin are in place.
What is left to do?
The rudder already has a doublesided adhesive tape to mount to the fuselage. There is a hollow in the fuselage for easy and correct mounting.
The receiver has to be installed and the antenna to be layed. The required receiver must be at least a 3-channel type (2 ailerons 1 controller).
The Transmitter must be capable of mixing aileron and elevator function (deltamix). Very useful is exponential-setting to 30%.
The flightbatterie
You will need a 3 cell lipo batterie with 200 to 2500 mAh and 3,5mm goldplugs. Please pay attention to the load rating. Both edf units together will draw 32 amps at 11 volts. The choosen batterie must deliver this to have a good launching. An tested batterie with 2100mAh and 16C rating should work in theory but the voltage drops to 10 Volts, giving 70 watts less than a 30C rated battery.
The battery is also beeing used to adjust the center of gravitiy.
It would have been nice, if the manufacturer had marked the cg on the bottom side of the plane. The detailed manual helps here, saying 230mm measured from intakes. Finally you need something to fix the battery in the plane. Here was a velcro fastener the best allowing later adjustement of cg.
Rudderadjustements:
The exemplary manual suggests:
rudder on neutral with max. 15mm travel and
CG on 230mm.
Testflights resulted in better flying and steerability when setting to
rudder 2mm high (instead of neutral) and
limiting travel to 10-12mm way, adding 30% Expo and
setting CG to 220 bis 210mm.
Launching:
The plane will be launched by hand. Logically first by a routined launcher. Some few steps and leveled launching and the eurofighter is airborne. Edf-typically mild plunge-down, cautious elevator holding and the eurofighter accelerates to climb up.
Flight:
Climb rate after accelerating is good and flightspeed for the intermediate modelpilot adequate. The model likes full power flying and is trouble free to maneuver. As with every edf-plane it likes spacious flying to give a perfect scale jet-impression.
Landing:
Really comfortable is the landing behaviour. The plane is very stable to fly without thrust. On the end of approach one pulls the elevator more and more and gets a very smooth touch down.
Impression:
The sound of two edf-units and the flight impression departs this model positvely from others. Absolutely respectful is the high grade of ARF and the detailed manual. The material is non sensitive EPP, which can be glued in case of accident. The two 56mm edfs seem to be hyperflows, successfully used by other manufacturers. The edfs are running smooth and deliver a weight/thrust ratio of nearly 1:1, very good for such a model.
Potential:
Carson will deliver a set for making the canards steerable. That will improve the elevator-steering but is not really needed. The edfs can be tuned by changing the motors. One Hyperflow is capable to deliver 720g of thrust at 4S lipo and 32 amps.
Conclusion:
Carsons Eurofighter is a well made ARF model for the intermediate modelpilot to start into edf-flying while keeping buildtime and cost low.
