Qx70 Motor / Prop Riser

thingiverse

The stock QX70 prop sits too low in the duct. I designed a very simple part that will help lift the motors so the props have enough clearance. It's a little more elegant than using hot glue and certainly looks better. There are two versions. The original raises it up by about 2-3mm. The "tall" raises it up an additional 3mm. You may want to experiment to see which ones work best for you. Printing Instructions: I used .20 layer height You will need a nozzle that is .40 or smaller to print this, as the walls are very thin. If your slicer struggles with printing the full model, check your nozzle settings. You may be able to adjust the nozzle size manually to .40 or less. You should be able to use just about any filament for this. I'd recommend ABS or a flexible filament so it holds up better in crashes, but even PLA should work. These don't even register on my digital scale. When printing with PLA, my slicer tells me the plastic weight is .38 grams. Installing Instructions: Remove propeller, and the rubber band that holds the motor wires. Lift the motor out of the holder, being very careful as you lift it so you don't damage the duct supports. No need to unplug the motor, but be careful not to push the motor with too much force, as you don't want to damage the wiring. Drop the prop riser into the motor holder. Shift the prop riser so it sits on top of the peg. Keep the wires out of the way so they don't sit in between the motor and the riser. There should be plenty of room for it to sit on. Push the motor back down into the holder. It should sit on top of the prop riser. Add the propeller back on and you should be good to go! Hope you enjoy this.
