Installation
Preparation
Remove the current drive train setup (propellers, motors, ESCs) from the DJI arms, remove the arms and clean
the ESCs solder pads. If you are going to reuse the motors, clean the top of bearings with a cotton-bud.
It is imperative to remove as much excessive weight from the platform as manageable before upgrading to the
endurance kit. Every gram will have a direct effect on the final flight time - e.g. 200 grams can easily mean 8
minutes less flight time. Consider shortening wires, thinner gauge wires, removing bullet connectors, NAZA
PMU, redundant screws, titanium screws, using PPM, lighter PVC heat-shrink, removing plastic casings and
similar type of nuances.
Arm length
Begin by finding the right cut point for the carbon fiber tubes (if needed). This depends on the size of the
propellers used, see the guide below for suggested lengths. Longer arms are supported (17-inch has been
tested) but you have to supply the carbon fiber tubes yourself (Ø16, 1.2mm thickness).

Measure from the end of the tube where there is a guide hole. This hole is used to mount the frame clamp later
on and keeps one end aligned - it should not be cut away.
Use a small hand-saw or other fine cutting tool to cut the tube to length. Apply gentle pressure and slow strokes
to avoid fraying the carbon fiber. Note that this is carbon fiber and the small fiber dust particles produced can
have an impact on your health if inhaled - always cut in a ventilated area with a mask.
