Page 5: Using This Manual
Using this manual Product Profile Introduction / general Stryder drones are professionally designed and built to perform in a demanding and ever changing industrial market. For flight controls see “Manual control of drone with transmitter” in this manual. The Stryder MK III airframe is a quad rotor (4 rotor drone). The Stryder drone is not permitted to fly any other payloads than the supplied and approved payloads.

Page 10: Remote Controller Diagram
Remote controller diagram Modes The Stryder drone transmitter has three modes for flight by default. The modes are controlled by SF and SC switches as shown above. GPS = Position hold mode. In this mode the drone will hold its current GPS position and elevation when the user gives no input to the transmitter sticks.
Page 11: Charging The Transmitter
Charging the transmitter The transmitter is charged via the USB plug in the back of the transmitter or the barrel jack plug on the bottom depending on model. When the light under the power button on the front of the transmitter turns off then the transmitter is charged.
Page 12 Moving the left stick to the left / right will rotate the Stryder about its center axis. Moving the right stick up / down will move the Stryder forward or backward in the direction the drone is facing. Moving the right stick left / right will move the Stryder to the left or right of its direction of travel.
Page 13: Calibrating The Transmitter
NOTE: Calibration of the transmitter is an advanced operation and done at the user's own risk. If you do not accept this risk then return the drone to Epoc for calibration. If transmitter calibration is required follow the following procedure.
Page 14 3. Press and hold the SYS button to get the system menu up 4. Press the Page up/Dn button five times until you see the calibration option 5. Now press the grey button on the right (OK button)
Page 15 Pixhawk transmitter calibration is as follows AFTER the transmitter has been calibrated as per above. The following are instructions on how to re-calibrate the transmitter on an EPOC drone using a Horus X10 transmitter SAFETY WARNING this procedure m ust be done outside in a clear area because the pilot may inadvertently arm the drone.
Page 16 1. Plug in the drone battery and turn on the transmitter 2. Ensure all trims are centered on the transmitter. Do this by bumping them one way or another then bumping them back. When centered the radio should speak "trim centre” 3.
Page 17 8. Click on "Calibrate Radio" and say OK (you are outside if the motors arm just disarm them) 9. It will then ask you to click OK and move all sticks and switches to their extremes. Go ahead and click OK. 10.
Page 18 19. Go back to the "Flight data" tab on the top 20. Note what mode the drone is in. Cycle through PosHold and Auto modes on the transmitter. Monitor that each mode shows up correctly. 21. Now flip the RTL switch. No matter what mode you are in RTL will override it and should say RTL on the screen.

16) After connecting to your local wifi click back on the map and pan / zoom around the area where you will be flying. Ensure to zoom to the level you will want to see when flying. This caches the map locally so that you do not need to be on the internet at the field. 17) Disconnect from your local wifi internet connection 18) Power down the transmitter and power it on again.
Page 24: Warnings
Warnings In-flight Normal flight conditions and instrument gauges Emergency procedures In the event of abnormal behavior such that the drone is not performing as expected. The following procedure should be followed: 1. If the planned autopilot course is not being adhered to the first action is to select the RTL switch on your Transmitter.
Page 25: Post-Flight
If they are then stop flight immediately and contact Epoc If one motor is quite noticeably warmer than the others on a regular basis then the drone should be sent in for service as a bearing may be failing.

3. Convert raw base station data to RINEX format by dragging and dropping the raw file on top of the appropriate conversion utility: sbp2rinex.exe for .spb (Epoc magic triangle base station) files, tps2rin.exe (Topcon base station). If using Trimble, Leica etc. for a base station contact the manufacturer for a RINEX conversion workflow 4.

Page 56: Battery Management
Battery management Battery lights and indications / maintenance Stryder MK I drones are supplied with 6S 22ah batteries. Stryder MK III drones are supplied with 12S 32ah batteries. These batteries are generally self sustaining but the user needs to follow guidelines in order to make them last as long as possible.

Page 58: Self Balancing
To turn the battery “on” or “off” the user is to perform a short push followed by a long push of the power button. After this you will see the white rectangle LED’s light up in sequence showing weather the battery has been turned on or off. If the battery is turned on the lights will “increase”...
Page 59 Lipo batteries have a maximum lifespan cycle before they need to be replaced. These batteries have an internal meter that counts charge cycles as well as other factors in order to estimate battery lifespan. To check total battery life first ensure the power is “off” on the battery. Typically it is never turned “on”...
Page 60: Warnings And Info
Warnings and info The triangle shaped LED’s have the following indications. Generally the user will only see one Red triangle light up and this is relatively normal. It is assumed that the user charges the pack with the “balance” mode selected and the user must review all cell balances to ensure they are within 0.03V of each other.
Page 61: Hour Meter Schedule
Routine scheduled maintenance can only be done by an Epoc Unmanned Inc. qualified service technician. If a maintenance schedule is not adhered to this will void all warranties on the product.
Page 62: Drone Takes Off Again After Landing
Drone’s artificial horizon is not level when drone is level This can occur with large temperature swings. Usually when the drone is left to sit level the AH will slowly return to horizontal position. Resetting level is possible but Epoc should be contacted prior to doing so.
Page 63: Downloading Logs
Downloading logs Telemetry logs (off laptop) 1) Browse to C:\users\toughbook\documents\Mission Planner\logs\QUADROTOR\1 2) This is where the telemetry logs are stored for each flight. 3) List the files by name and review the dates on the files. Take all files with the date for review and copy them to a new folder on your desktop.
