[ajw61185] made a video overview of a radio-controlled A-10 jet modified to spew a hail of harmless Nerf balls as it strafes helpless cardboard cutouts of T-72 tanks on a bright, sunny day.
The firing assembly in the jet comes from a Nerf Rival Zeus Blaster, which is itself an interesting device. It uses two electric flywheels to launch soft foam balls – much like a pitching machine. With one flywheel running a little faster than the other, the trajectory can be modified. For example, a slight topspin gives the balls a longer and more stable flight path. Of course, foam balls slow down quickly once launched and at high speeds the aircraft can overtake the same projectiles it just fired, but it’s fun all the same.
Cramming the firing assembly into aircraft took some cleverness. The front of the jet contains the flywheel assembly, and a stripped-down removable magazine containing the foam balls fits behind it. A flick of a switch on the controller spins up the flywheels, and another flick controls a servo that allows the balls to enter the firing assembly and get launched. The ammo capacity on the jet is low at only twelve shots per load, and it fires all twelve in roughly half a second. Since the balls are fired at the ground in a known area, they’re easy to retrieve.

[Arron Bates] is a pro R/C Pilot from Australia. He’s spent the last few years chasing the dream of a fixed wing plane which could perform unlimited spins. After some promising starts with independently controlled wing spoilers, [Arron] went all in and created The Super Honey Badger. Super Honey Badger is a giant scale R/C plane with the tail of a helicopter and a soul of pure awesome.
Starting with a standard 87″ wingspan Extra 300 designed for 3D flight, [Arron] began hacking. The entire rear fuselage was removed and replaced with carbon fiber tubes. The standard Extra 300 tail assembly fit perfectly on the tubes. Between the abbreviated fuselage and the tail, [Arron] installed a tail rotor from an 800 size helicopter. A 1.25 kW brushless motor drives the tail rotor while a high-speed servo controls the pitch.
[Arron] debuted the plane at HuckFest 2013, and pulled off some amazing aerobatics. The tail rotor made 540 stall turn an easy trick to do – even with an airplane. Flat spins were a snap to enter, even from fast forward flight! Most of [Arron’s] maneuvers defy any attempt at naming them – just watch the videos after the break.
Sadly, Super Honey Badger was destroyed in May of 2014 due to a structural failure in the carbon tubes. [Arron] walked away without injury and isn’t giving up., He’s already dropping major hints about a new plane (facebook link).
