Because of the high weight of the prop the mounts for the Warlock are both zip tied and bolted to the coro. At each of the 8 post mounts you will need a 3.5″ long 1/4 x 20 bolt, (2x) 1/4 x 20 nuts and a 1/4″ washer in addition to zip ties. Start by embedding the 1/4 x 20 nut into the bottom of all the mounts. The easiest way to insert them is to temporarily insert the bolt from the top of the mount and thread the nut onto the bolt. As you tighten the bolt it will pull the nut into the mount. You can then mark on the prop where to make the holes for both the zip ties and for the 1/4″ post mount bolt to go through the coro. While the prop may look symmetrical, the hole patterns at the outer mounts vary by a couple of millimeters. The mounts were designed using the average hole locations and thus holes on the prop will not be perfectly centered with the holes on the mounts. There is plenty of extra clearance, so just center the mount amongst all the holes. After the holes are made on the coro you can zip tie the mounts to the prop. Insert the EMT into the mounts and mark where the holes need to be drilled for inserting the bolts through the mounts. If your prop was slit in half for shipping, it’s always best practice to run the continuous piece of EMT perpendicular to the slit. Next drill 1/4″ holes completely through the EMT at all the hole locations. Glue the bushings into the PVC cross using epoxy or super glue and then feed the EMT into the mounts with the completed PVC cross in the center. At each post you will insert the bolt from the top of the mount and tighten it against the embedded nut at the bottom of the mount. Just careful not to over-tighten or you could crack the mount. The excess length of the bolt should now be sticking out of the front of the prop where you will insert the washer and another 1/4″ nut and tighten that down until it fits snug.
3D printing parts is a slow process and we have a whole print farm running 24/7 to fulfill orders and build stock of the more popular items. If you order a product on backorder we will move it directly to the print queue where it will be printed as soon as possible. While normal processing times for most orders with backordered items is less than a week, it can fluctuate from time to time around 1-2 weeks. Very large orders can also experience longer than normal processing times as well. If processing times are expected to be longer than two weeks before shipping, there will be a banner at the top of the website indicating the expected wait times. Additionally very large orders could have longer delays due to the vast number of printer hours required for production of the parts. We will contact you and let you know the expected production time if it were to exceed the estimated timeline for very large orders. See the FAQ page for more info.
All of our 3D printed parts use PETG filament which provides good flexibility and resistance to UV exposure when used seasonally.
