FunJET goes from launch to super ballistic in a flash yet is docile at slow speeds making landings gentle. Multiplex ELAPOR Foam construction gives the FunJET unparalleled durability and strength.

This EPP foam jet is positioned right between the Microjet and the Twinjet. Logically spoken, this one should be more stable than the Microjet, because of its larger size, and cheaper than the Twinjet, due to the fact you only need one motor and speed controller.

Let’s find out!
The first thing I noticed when I opened the box is the quality of the packaging. All foam parts are carefully wrapped in bubble plastic, and all the small parts are packed in a little box. Taped on the back of the box is the reinforcement bar for the Wings. This kit is, just like all other foamies from Multiplex, very easy and very fast to assemble. It only took me 2 hours to get the plane up and running (without painting it).

The model consists of three main parts: the fuselage and the two wings. It only took me about five minutes to glue the whole plane together using CA glue (cyanoacrylate). Perhaps another way to glue it is using EPP foam glue. The advantage of this one is the elasticity of the joint (but it takes longer to dry up). In this case CA was good enough.

The wing parts have pre-moulded joints, making it very easy to align perfectly. Right after that, I glued the two tail parts on the wing. Same thing for the two tail parts, each fitting perfectly in the precut cavities, making it almost impossible to fail on this stage of the building. The composite wing reinforcement bar is easily fitted in place, and also should be firmly glued in place with CA.

With the wings an tails assembled, it already looks finished!

The next ting to do is to insert the 2 flaperon servos into the premoulded cavities in each wing. A bit of double sided tape is sufficient to hold the servos in place, making it easier to remove the servos afterwards for eventual servicing. I used some JP micro servos, costing each 8€, and they are doing their job well! There are also little gutters precut in the wing to fit the wires, which are leading to the main space in the fuselage. A bit of masing tape is enough to hold them in place.

The next step is the installation of the Motor. In this case I used a Megamax Brushless motor. The motor mount is another well thought part from Multiplex! It consists of 2 parts: the outer part which has to be glued on rear part of the fuselage, and an inner part to which the motor is screwed on. Those two parts fit together using 3 additional screws. The third screw is used to adjust the alignment of the engine, making it possible to easily correct the up- or downlift of the plane.

The last bits of assembly are restricted to installing the speed controller, the receiver and the Battery, using the Velcro straps included in the kit. The last step is mounting the cockpit on top of it all, using the little fixations provided in the box.

A complete decal sheet is also provided for decorating the plane using flame spatters. Looks very nice! After 2 hours of building, it’s finally time to test the beast!

A big advantage of the Funjet is the easy way to launch it. It’s perfect for hand throwing launching. The risk of hitting the propeller with the back of the hand is minimal. The ideal way to throw it is at a 30° angle, nose up, throttle at 60%.

There it goes! The Funjet has no problem to get going, and pushing the throttle lever to the maximum quickly sends the Funjet hundreds meters high in the sky. The climbing rate and speed of this model is overall very impressive!

Overall stability is excellent! (Much better than the smaller Microjet)
Maneuverability is also excellent in comparison with the Twinjet. It is far more responsive due to the fact it only has one central engine. After a serious bit of stunting and high speed low passes, it’s time to get it back on the ground. Landing is no issue with the Funjet, as it glides gently back to the earth, even with throttle back to zero position.

The only modification Iwould suggest to the original setup as described by the manual, is applying some reinforced duct tape on the bottom of the fuselage, to protect it from harder landings on sand, stones, or even grass.
