Old Version Mini Talon Convertible Landing Gear

thingiverse

THERE IS A NEWER VERSION OF THIS HERE: https://www.thingiverse.com/thing:3155583\r\n(No longer need the collar or steering horn)\r\n\r\nREAD THE NOTES/UPDATES SECTION BELOW BEFORE DOWNLOADING THIS!!!\r\n\r\nEven if you don't want to install landing gear right now, you can still mount the front skid and install a blank plate which performs exactly like MarkQ's original front skid. Then when you're ready for landing gear, you can easily slide the servo/wheel mount into the slot, plug in the servo and bolt on the rear gear and go. It takes less than three minutes to convert from skids to wheels!\r\n\r\nParts Needed:\r\n\r\nUsed for front nose gear:\r\nhttps://www.banggood.com/DIY-60-Level-Tail-Wheel-Bracket-Assembly-for-RC-airplane-p-908726.html\r\n\r\nUsed for rear gear:\r\nhttps://www.banggood.com/2mm-Aluminum-Landing-Gear-Set-For-25-40-Class-Electric-RC-Airplane-p-1151154.html\r\n\r\nTwo MR128ZZ bearings for the front shaft: (FastEddy is my favorite eBay seller for quality bearing in the USA shipped fast!)\r\nhttps://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=MR128ZZ&_sacat=0\r\n\r\nOne Emax ES08 metal gear servo. (analog or digital):\r\nhttps://www.banggood.com/EMAX-ES08MA-II-12g-Mini-Metal-Gear-Analog-Servo-for-RC-Model-p-935479.html\r\nOR\r\nhttps://www.banggood.com/Wholesale-Emax-ES08MDII-Metal-Digital-Micro-Servo-p-68600.html\r\n\r\nI'm not specifying the control linkage since there are many options for this. You probably already have something that will work laying around.\r\n\r\nFRONT:\r\nThe black control arm that comes with the front gear linked above gets its length cut down past the slot and you'll need to drill a hole for the servo linkage. (I'm working on a new design that makes this easier and doesn't require the steel collar, check back and read the notes section for further details.)\r\n\r\n\r\nREAR:\r\nThere are two choices for attaching the rear gear to the belly mount. In my case I used the hexagon nut mount with hexagon nuts with .360" flat to flat (23/64" wrench size).\r\n\r\nOR\r\n\r\nChoose the drill (#7/.201") and tap (1/4-20) version. DO NOT GO ANY BIGGER, remember this is not a solid piece! (another reason to have at least four vertical shells!)\r\n\r\nIn both cases, USE NYLON SCREWS to hold gear to belly mount! This will allow them to break in a severe landing rather than ripping the gear off the plane!\r\nYou'll need to drill two new holes slightly larger than your nylon screws, and 2.75" apart on your aluminum gear (1.375" from center) See notes below if your screw heads head the curved part of the gear\r\n\r\n\r\nGluing pieces to fuselage:\r\nOnce you have everything fitted and are satisfied, use either E6000, or Uhu Por to glue the front skid and rear belly mounts into place. Once this is done you may then cut the foam out to fit the servo for the front gear. If you choose to make the front gear permanent I suggest you also glue the servo house to the foam to help strengthen this area and prevent tear out on a rough landing.\r\n\r\n\r\nNote: I changed out the wheels that came with my gear for larger wheels since I use a grass runway.\r\n\r\nPlease let me know if I missed anything... There is a lot going on to remember!\r\n\r\nhttps://youtu.be/qJZGLSQbhl0
