Aircraft Update : Janowski J-1B 'Don Quixote' by FJMAero


A month ago I've posted the complete review of this small and high-quality aircraft, showing you all its details. This week FJMAero released the v1.1 of the J-1B, contemplating a lot of improvements and new features, which in my view, should get an update review. Let's start the review and see what really changed and in case you weren't completely sure of buying it when it was released, this may be the time to add the aircraft to your fleet.


Just like its predecessor, the J-1B still has those high-quality textures and beautiful 3D modeling, and by now you can already see some changes in both interior and exterior.

Let's start with the exterior changes. As you can see, the J-1B received a brand new livery named Busy Bee, which had its design inspired by a honeycomb, at least that's what I think, resulting in the Busy Bee name. The Hirth F-33, Warp Drive propeller and landing received some animation fixes which can sometimes be noticed during your flight.

The J-1B received many other major changes, starting with the flaps. In this update, FJMAero included a 3 position, UP, 1 and 2, electric flap system which can be controlled by the flap selector unit on the panel. The FMOD actuator sounds for the flap motors were also added to the aircraft. The flap modeling is ok but the controller is pretty nice, good modeling and lighting.

Another major change was the addition of lights, this way you will be able to do some local night flights. The designer added landing, beacon, nav and flood lights, which can all be controlled by the lighting panel installed in the cockpit. All of them were very well modeled and implemented in the aircraft. Pretty nice to see them in darker hours of the day.

The interior didn't receive many changes, most of them are related to other systems like flaps and lights. Probably the most noticeable change is the addition of the Aileron trim and its instrument gauge right next to the pitch trim gauge. Now you also can enable and disable the canopy panel transparency by clicking at the compass.

Last but not least, the J-1B received a fix that turns the fuel pump on when you click at the "RUN" switch, previously it started together with the battery, this way the engine won't overflow while you set up the GNS430. The last change is related to the paintkit, the wing template was adjusted due to the addition of the flaps.



The Janowski J-1B by FJMAero was one of the best ultralights for X-Plane when released, reflecting the hard work of the designer. Now that it has received its first update, new features were added to the J-1B as well as some little improvements. Just like in its previous version, this little aircraft has no problems at all and it will be quite hard to note some possible improvements, maybe increase the details in the aileron and flaps area, but it isn't required.


As I said in the first part of the review, if you weren't sure of buying the J-1B, this would maybe change your mind. Well, I've already recommended the aircraft in its release review, and wouldn't make any sense if I didn't do that after upgrades, so yes, I completely recommend this plane.


FJMAero isn't very known as a designer for X-Plane, but I am sure that if the designer keeps this high-quality level, I am sure that they will get bigger and develop even better add-ons. The Janowski J-1B is for sure one of those little planes that will bring a smile to your face while flying it.






The Janowski J-1B by FJMAero is available in the X-Plane.Org Store here:


Janowski J-1B


Price is US$19.95



The J1-B is a home-built aircraft design originally conceived by Jaroslaw Janowski and Witold Kalita in the late 60’s. The design featured a high-wing single-seat configuration with rearward mounted engine on top of the wing.
The FJMAero J-1B is representative of a fiber glass airframe powered by a Hirth F-33 air-cooled two-stroke engine producing up to 28 HP, with design loads of +6/-3G. The J-1B is flapless and comes with a fully movable elevator trim to compensate the effects of the high-thrust line above the center of gravity.

Our J-1B is a designed to provide the virtual pilot with an aircraft that is easy to handle, offers excellent visibility and exhibits interesting flight characteristics for those that enjoy stick and rudder, seat-of-pants flying. Ideal for short scenic flights, cross-country VFR and is light aerobatics capable.
  • Highly detailed 3D interior and exterior model with many fine details to discover
  • High-resolution (4K) physical based rendering (PBR) texture sets to showcase surfaces ranging from painted resin, spray paint, metal, seat fabric, dust effects, all the way to leather for the dust cover at the base of the control stick
  • Animated controls, control rods and surfaces, canopy, fully articulated rudder pedals with differential braking and cockpit switches
  • Custom XLua driven ignition panel to provide a robust engine and avionics start-up, including custom commands that can be assigned to joysticks or other hardware peripherals. Open the fuel valve, turn on the battery bus, switch the ‘Run’ button to on and press the starter to bring life to the Hirth F-33 and the ‘Warp Drive’ propeller.
  • High-resolution flight instruments designed from the ground up to maintain clarity at all viewing distances. Includes a highly detailed 3D face for the GNS 430 (X-Plane 11 native)
  • Full-bodied FMOD sound set that includes (but are not limited to):
    •  Hirth F33 engine sounds
    •  Buttons and switches, including the GNS430
    •  Engine starter and fuel pump systems
    •  Wheel sounds for impact, rolling and sliding
    •  Cockpit shake/vibration noise based on ground roll
    •  Wind noise on the canopy based on airspeed
    •  Sideslip air noise on the airframe and canopy
    •  Custom stall horn providing incremental feedback based on angle of attack
    •  Realistic sound attenuation when closing/opening the canopy
  • Custom Clark Y airfoil. Flight model tested with standard and experimental flight model (11.41+), with the latter being preferable for those that enjoy stick and rudder flying.
  • Four liveries including ‘Fire Red’, ‘Blu’, ‘Moon’ and ‘Blank’. While the first three come with custom PBR textures for each paint scheme, the Blank scheme has a neutral PBR set to assist with repaints. Each livery features its own unique internal textures
  • A unique tail number repaint texture that allows customisation of the fuselage tail numbers, the pilot name under the canopy, as well as the number plaque on the instrument panel without having to repaint the entire aircraft. An easy to use registration Photoshop file is provided. Customise your J-1B and make it your own.
  • Paint kit designed from the ground up to be easy to repaint (external and internal), including colour coded layers in Photoshop with instructions to preserve PBR materials, as well as UV island guides to assist livery painters (see manual for more details). The following diffuse paint sets are provided:
    •  Fuselage
    •  Wings
    •  Cockpit
    •  Instrument pod (excluding instruments)
  • Fully detailed pilot in external views with custom headset and aerobatics-ready harness.
