DJI F450 adapters for 0.5" X525 aluminium arms

Warning: If you're using the type of landing legs in these pictures (DJI landing skids), make sure to use all four screw holes! You may have to drill out the frame for the smaller arms. Without these screws, the legs will function like a lever when landing and may eventually cause damage to the adapters. This happens with both the DJI and original arms, but much more quickly due to their material. Update: January 29, 2015: All versions updated. The rear part is designed differently (no longer taken from another source), made lighter and easier to print. A one or two layer thick roof has been added in the back opening now. This helps prevent ABS curling on the arc and gives it extra protection against stress. The most current update on January 23, 2015: The knurled version has a larger hole. To avoid damaging your nut's screw holes when they start to wear, carefully use a metal drill bit (2mm) after cutting away at the plastic in each of them. This makes sure you don't mess up the internal thread or the metal on top. Just remember to regularly clean and dust off your metal drill bit as well. The January 18 update has changed all models. There is now an additional thin cover around the 4mm hole inside, making it much easier for printers to build bridges instead of adding extra difficult supports in place of a hard-to- remove one that sticks really tight into the square hole when built by support and creates more of an obstacle. These updated models print without any supports required. For an even cleaner surface, try tapping gently on each side to separate it, opening up your square holes with either the tip or screwdriver handle. Your printer may still need you to carefully file the area slightly in order to match calibration expectations. "Knurl" was also added as a new spare arm one - that model's purpose is using metal inserts similar to these (available online). These adapters have already been tested on successful flights with no damage at all to their internal workings! One more frame variation I found uses these specific arms but are really small. Because of its design and plastic parts in general, the arm might just not sit very comfortably - you'll be better off creating my own replacements from scratch using the following set of 3D-printed items based upon one that originally belonged to an old dirkdirks drone. There's only room for threaded inserts inside four out of these six total screw holes: don't put them on those others; instead, simply stick with regular metal nuts to add a bit more stability without getting too close. Also note: there won't be space left over at all if you use bigger screws! That will cause major damage before flight day! They've been made light and very strong as possible with each screw being threaded from the underside by their metal inserts instead, providing more resistance to external forces and better stability in mid-air flight conditions when taking turns. As for actual durability: just give a little twist using pliers (and it should work well) on these particular parts you may still see an original version without metal supports; but don't let worries scare you away. These X525 adapters can actually help improve any quad's aerodynamics by offering improved lift-off characteristics compared against stock counterparts - so do check those before upgrading your system setup, as that's when performance boosts kick in and takeoff efficiency goes way up too!
