SebArt MB-339 XS 120mm Jet 1.9m + JP Hobby 120mm 12S (Blue/White/Red/Green) PNP (+ Landing Gear)

Combo with EDF 12-blades 120mm JP Hobby V2 100% metal with motor 12S 760Kv and ECS 150A + Ubec 12A

Following the success of the MB-339 Mini version in EDF and kerosene, Sebart offers a larger version with the possibility of installing both versions of the engine.

The MB339 1.9m Jet ARF is the big brother to the 90mm MB339. This sport jet model is largely designed off the full-scale MB339 and modified by adding the ultimate aerodynamic ideas of modern pattern models. Combined with Sebastiano's 15 years of experience in flying jets, the result are surprising! The innovative design of the MB339 XS is due to the combined lightweight composite fuselage and built-up wood flying surfaces which allows the MB339 an impressive precision and smoothness at any airspeed and flight condition. 

As the all other products of the brand, the construction and the finish are of irreproachable quality. The Mb339 XS can be flown with a 12 Blade 120mm EDF unit with 12S 5800mAh LiPo power or a P60 to P130 Turbine, either way this sport jet will perform!

EDF Ducted Fan JP HOBBY 120mm 12 blades + 12S Motor 760Kv

100% CNC aluminium JP Hobby EDF unit (shroud and rotor) for 12s

Description

  • Jingpin Hobby uses High grade aluminium alloy material for highest rigid structure and lightest weight.
  • The shroud acts as a heat sink, removing heat from the motor. This design creates a more efficiently running motor and will provide peak performance while extending the lifespan of the motor.
  • The highly rigid structure design is capable of running up to high RPM to produce extremely high efflux velocity for maximum speed and efficiency.
  • Anti Blade flying out design,the Blades be safety kept in the shroud and without damage.It is the best replacement for your plastic or carbon shroud if you want to have a safety EDF fan.
  • Each metal blade is precisely made of High Grade Aluminum alloy to generate jet airflow. Every blade has been tested for 8 hours of metal fatigue test as well as in the dynamic balance machine for calibration, making it bring a better and safer user experience for every RC fan.
  • You could assemble our EDF system with any other motor without losing dynamic balance effect.

The motor and fan unit comes assembled and balanced from the factory.

Measures

About the above measures : they have been read on the test bench with the intake lip on the unit. The measures have been made using a bench stabilized power source. Results may changed depening upon your equipment and situation.

 Description / LiPo   12s (44.4v)  12s (48.0v)  
 Thrust:7.5 kg  8.62 kg 
 Current:112 A127 A
 Power:4972 W6096 W
 Recommended ESC:   120 A / HV 150 A / HV 
 Recommended battery:   5000mAh 40C   5000mAh 40C 

The controller should be chosen 20% over rated due to the long lasting load.
LV = low voltage controler up to 6s, HV = high voltage controler above 6s.
Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.
Operating the motor outside of the specifications listed above can either damage the motor, battery or esc. It is important that these components are set up properly. Failure to do so can void the warranty. It is strongly encouraged to use a Watt Meter to test the watt and amp performance when setting up a new system. If the output is above the factory recommended specs, then it needs to be adjusted by the esc. The timing and throttle settings on the esc can help to set the appropriate levels.

WARNING: This turbine is delivered with the engine cover shown in the pictures. This engine cover significantly improves the flow of ejected air without this improvement can be considered an improvement in performance of the turbine. On the other hand, the engine cover significantly reduces engine ventilation and may in some cases cause it to overheat. We advise you not to use the engine cover or to check that the engine temperature is not excessive after a flight.
