4481 Hailfire Droid is a TECHNIC Star Wars Attack of the Clones set released in 2003. It contains 681 pieces to construct a TECHNIC Hailfire Droid. The set includes a hailfire droid, built out of TECHNIC pieces. It has two large wheels angled outwards. They are connected to the body of the vehicle by brown TECHNIC beams. These wheels have the ability to turn, meaning that the droid can move when pushed. The body of the vehicle has a single sensor 'eye', made of a transparent-red piece which was commonly used on Bohrok sets from the BIONICLE theme. It is armed with two large missile arrays, each with fifteen missiles. The IG-227 Hailfire-class droid tank was a droid constructed for the InterGalactic Banking Clan. These droids were present during the First Battle of Geonosis in the Clone Wars, where the Confederacy of Independent Systems deployed them to counter the clone trooper invasion. Hailfire droids were able to carry a total of thirty warheads. A single warhead had the ability to destroy an AT-TE.
Do not modify it. Challenge the Republic with the Hailfire Droid! One of the most awesome weapons of the Separatist armies, the Hailfire Droid features 2 massive launcher pods and immense hoop wheels for travel over any terrain!My Parts: You need to be logged in to see your Set List.

Axle and Cross-Block Mounting Hailfire Droid Wheel as Ring Gear Rotational Maths for Orrery Design In the early days of LEGO Technic, the one and only way to set up gear trains was like this: vertical and horizontal spacing Table of gear arrangements shown in the photos: vertical, horizontal spacing (in LPH, LSS) 8 36 44 LGDU = 21.96 mm 3 LPH + 2.5 LSS 12 14 26 LGDU = 12.98 mm 4 LPH 12 24 36 LGDU = 17.97 mm 5 LPH + 1 LSS 12 40 52 LGDU = 25.96 mm 3 LPH + 3 LSS 14 20 34 LGDU = 16.97 mm 5 LPH + 0.5 LSS 14 24 38 LGDU = 18.96 mm 3 LPH + 2 LSS 14 36 50 LGDU = 24.95 mm 1 LPH + 3 LSS 16 20 36 LGDU = 17.97 mm 5 LPH + 1 LSS 24 24 48 LGDU = 23.96 mm 7 LPH + 1 LSS 24 36 60 LGDU = 29.94 mm 7 LPH + 2.5 LSS The use of axles and cross-blocks (such as part 6536) allows for much more flexibility in how you position your gears. the same, with gears added The axles and cross-blocks and other little connectors allow for far
more variety in how each hole is positioned. This is similar to the arrangement of Technic bricks and plates shown above, except that you can use arbitrary spacing along one axis (the vertical direction in This technique allows for the creation of a variety of gearing ratios in a standardized geartrain "module". For example, see my Stacked Turntable Module (method 3) Building Instructions The large wheel in the picture was only ever used in one set, 4481. It is a ring gear with 168This is exactly three times the 56 teeth on the outside of the Technic Turntable (part 48452cx1), which means you can just fit three across inside the ring. I looked for another way to construct a concentric planetary gear mechanism, and here is the Dual Concentric Planetary Gear Arrangement using Hailfire Droid Wheel Video of the Hailfire mechanism The turntable in the center serves as the sun gear; the z36 and z40 gears are the planets (the planet carrier is hidden below the gears)
and the Hailfire Droid wheel is the ring gear. All pairs that should be meshed are just right, except two: the red gear is just a little bit shy of the outer ring, and the two black ones (the inner one being the turntable) are not meshing with eachThe rest move really well and really smoothly. out of 5 is all it takes to keep the assembly centered and stable, the construction works as intended. The z36 and z40 gears are all held together by a symmetrical arrangement of parts 6629 and Inside the turntable is a normal planetary gear setup — here the sun and planet are yellow and blue z8's, and the turntable serves as For a smaller (perhaps more practical) planetary gear solution there is the relatively newer in some of the "Power Miners" sets (8059, 8959, 8960, etc.) and a couple Ninjago sets like 2518 "Nuckal’s ATV". inward-facing teeth around the inside of a wheel with ribs and spikes Here is a way to construct a differential without a differential
In a normal differential (shown on the left) the rotation of the housing (dark gray) is the average of the rotations of the two grayAs used in a vehicle, the drive goes into the housing, and the wheels are driven by the two axles. In the alternate differential (on the right) the two gray axles are connected (so they are the same axle), and the two pairs of dark grey gears move independently of the axle. The motion of the central axle is the average of the rotations of the two pairs of dark gears. vehicle application, the drive power would go into the central axle, and each wheel would be driven by one of the dark gray gears. The little tiny teeth on the dark gray gears (not present on the differential housing) allowed me to make this somewhat whimsical orrery depicting a single planet with a moon, orbiting a triple star Orrery Based on the Inside-Out Differential Here is what it looked like after I added a stand: Forest Hills Robotics League, building tips (date unknown)
