Landinggear AtomRC Killer Whale

prusaprinters

A langinggear for the AtomRC killer whale. It fits in the designated spot in the fuselage. You need M3 bolts and nuts to srew it in the fuselage. All the holes for the carbon rods are designed exactly 3mm so for easy assembly i recomend to drill them out with a 3mm drill. The legs are made of 3mm(113mm long) carbon rods and are glued in the printed parts with superglue. The axle I made also from 3mm(40mm) carbon rods and are glued in the wheelmounts. The wheels are made of 2 parts, the rim and the tire. The rim is printed from PLA whlie the tire is printed from a flexible material. I used TPU. They just "snap" togeter and should not come lose anymore. Before you install the wheels, make sure that they spin freely on the axle!! To prefent the wheel from falling of the axle, there are small rings included (nut.stl) glue these to the end of the axle. The front wheel needs a little more work. you need to cut a 30x30mm squere, use the Printed Base part as template. I used the method from a video from Painless360: https://www.youtube.com/watch?v=idm1SjtYv2g the Top and Base parts screw wit M3x6 bolts togeter, you can also use longer screws, just sink them in the foam. the actual wheel is a tailwheel from aliexpress: https://de.aliexpress.com/item/33010426661.html?spm=a2g0s.9042311.0.0.4d314c4db5MPLZ the 26cc version!!! drill out the center one of the 3 mounting holes of the wheel. i also designed small springy parts that go between the servoarm and the wheelarm. these sould reduce some stress on the servo. But you can also just use steel push rods. the whole from wheel assembly then gets glued in the spot. the origilan plywood plate is not needed here. https://www.prusaprinters.org/prints/77219-landinggear-atomrc-killer-whale Print Settings Printer Brand: Prusa Printer: i3 MK3 MMU 2Rafts: No Supports: YesResolution: 0.2 Infill: 20% Filament: PLA PLA Notes: PLA parts: 0.2mm Layer; 2 outer shells; 4 top/bottom layer; 20% infill Only the Wheelmount could need supportmaterial.
