PILOT OPERATION HANDBOOK
DJI S-900/Zenmuse
This book is offered in a format so that pilots can customize the checklists to their exact needs. Please print
out this handbook, make notes while watching the video regarding the checklist, then change the wording
and order to suit your needs. Then print out the revised form and laminate it in plastic. Use it every time you
operate your aircraft. Keep the log books regarding the following:
1) Pilot flight time
2) Aircraft flight time
3) Aircraft maintenance and updates
4) Battery usage, date put into service, voltage, mah vs time
Print out and make readily available the error message legend of various flashing lights. Know what to do
without hesitation should you observe warnings.
Insurance is a must! Not only will it be expensive to repair your aircraft in the event of an incident, if you
injure bystanders or damage other people’s property you are liable for damages which could run into the
millions of dollars. One insurance company which currently writes policies on sUAS is
www.Transportrisk.com
Errors & Omissions should be sent to customerservice@troybuiltmodels.com. We will promptly update the
POH for everyone to have the latest updates available.

SECTION 1
GENERAL
NOTE: In an effort to minimize costs and maximize spare parts availability, many COTS (commercial off
the shelf) components have been utilized. Some may have slight modifications to better suit this application.
Most COTS products have separate data sheets, assembly manuals and instruction manuals. They are
reference in this document, with key factors being emphasized.
As with all high technology products utilizing constantly evolving software, it is important to periodically
check for online upgrades to the COTS components, including hardware, firmware and software.
WARNING: Great care must be taken with the batteries. Much of this manual and supplemental information
is devoted to the use and care of the batteries, especially the flight batteries. They are less volatile than
gasoline, though they should be treated with the same respect. Become very familiar with proper techniques
of their use.
