Ignis Operations Manual
Drone Amplified
Figure 8.3.2c: Cleaning the oval cutout where the Hopper and Dropper mate.
Build up of antifreeze or ash here could cause the Dropper to stick to the Hopper and
not emergency release properly when triggered, allowing an in-flight fire to propagate to the
rest of the drone.
Depending on the operating conditions, the Dropper may occasionally need to be
partially disassembled to get completely clean. We recommend not doing this procedure in
the field but rather as part of a regularly scheduled maintenance in a controlled
environment where it is less likely small parts could be lost.
Using the 2.5mm driver included with IGNIS 2, remove the 4 socket head cap screws on
top of the Dropper shown in Figure 8.3.2d. The top of the dropper and the slipper block can
both be removed and cleaned individually. A solution of hydrogen peroxide and vinegar will
remove staining from potassium permanganate and compressed air can help clean out
small crevices and corners. After cleaning is complete, a drop of dry lubricant on each
bearing on the slipper block will prevent corrosion.
