Product Review

In 2017, HobbyKing released an ever-expanding variety of interesting and inexpensive foam board composition airframes that were designed to be primarily assembled using hot glue. Plenty of park pilots with a penchant for jets perked up with the appearance of a trio of stand-off scale, pusher propeller-powered jets at the almost unbelievable price of less than $20 per kit!

Completion of the HobbyKing Glue-N-Go F-35, Su-27, and J-20 kits requires but a few inexpensive nine-gram servos and a 300- to 400-watt brushless power system. Many pilots likely already have the required electronic components squirreled away in their parts boxes.

The foam board airframe components come out of the box with brightly colored, preprinted graphics already applied. The F-35 reviewed in this article is bedecked in a satisfyingly savage-looking—albeit fictitious—Canadian Air Force tiger scheme. Lengths of both surface-mounted and embedded carbon-fiber rods give these foam jets the rigidity necessary for flight.




This colorful foam board composition profile kit goes together quickly using hot glue.


A thick, plastic X-shaped motor mount is included in the kit and can be adjusted during assembly to optimally position the propeller in the provided slot. Although hot glue works for most of the assembly, the relatively quick cure time of this adhesive precludes pilots being able to use it for some of the larger pieces of the airframe.

If the pieces being glued together feature a lot of surface area, the slower cure times and superior wicking of Deluxe Materials Super ’Phatic! (deluxematerials.co.uk/en) or Beacon Foam-Tac (foam-tac.com), make them the adhesive of choice.

When gluing the bottom of the fuselage to the two side pieces of the airframe, pilots should note that the side pieces are not designed to mate to the bottom of the fuselage at 90° angles. They will instead need to be positioned to intersect with the fuselage bottom at identical shallow angles.

A scrap of foam board is included in the box to help builders properly angle the canted, twin vertical stabilizers. After the entire airframe has been assembled, pilots will want to lay small reinforcing fillets of either foam glue or hot glue along all seams and joints. The only control surfaces used on the F-35 are on the rear of the horizontal stabilizers. This requires that pilots have a transmitter capable of doing a delta mix for elevons.

The assembly manual suggests that pilots can use a 1,300 to 2,200 mAh LiPo battery. There is an abundance of space for the battery beneath the hinged access door. A 3S 1,000 mAh LiPo battery positioned toward the forward end of the battery bay allowed the review model to balance near the recommended CG (center of gravity).




Access to the flight battery is made via the large access hatch on the underside of the fuselage. Three embedded carbon strips give this profile jet appropriate rigidity.


Pilots who are not accustomed to hand launching a model will find that these profile jets are the perfect vehicle with which to develop good tossing techniques. Pinch-grip the fuselage dorsal near the CG and give the jet a smooth, underhand toss. Best results will be attained if the model is released at as shallow of an angle of attack as possible.

Pilots who are confident that they will not forget to follow through when hand launching, might consider running up the throttle to mid-position before initiating the throw. The safest approach is one that will assuredly prevent a painful propeller strike across your fingers while launching. Wait until after the model has left your hand before advancing the throttle.

Bringing the F-35 back in for a landing is as simple as pulling the throttle back to a low setting and floating the model in. This lightly loaded model can practically be plopped at your feet. Pilots planning to operate from rougher runway surfaces should protect the underside of the foam board fuselage from excessive damage by applying a thin layer of transparent tape or vinyl.

This profile jet can be handily tossed around the sky and is capable of performing all sorts of aerobatic tumbles and loops. High-alpha maneuvers and inverted flight are also well within its repertoire.




The key to easy hand launches is gripping the model’s fuselage by its dorsal ridge near the CG, and giving it a smooth, underhand toss.


Pilots who enjoy modifying their aircraft and who would like to expand this one’s in-flight capabilities might wish to explore adding rudders to the vertical stabilizers. Doing so is sure to expand the F-35’s in-flight abilities to include spins and knife-edge flight.

The HobbyKing Glue-N-Go jets offer park pilots a quick-building trio of extremely affordable pusher-powered profile jets. The electronics required for completion are exceptionally wallet friendly because many pilots might already have the needed servos and brushless power system lying around their hangars.

Pilots with younger children might find HobbyKing’s brightly colored pair of Glue-N-Go novelty flying fish models, distant cousins to these pusher profile jets, a great way to pique the interest of the next generation of park flyer pilots.
