Manufacturer: Draganfly Innovations Inc 

Model: X4P-MOTOR-1C 

Revision: HC4212-480-C 

 

Fuel/Energy System

Dual 4 cell 14.8 Volt 6750mAh lithium polymer battery with integrated protection and logging 

circuit. 

Method of Take-off/Launch 

VTOL, no external equipment required. Altitude control assisted by barometric pressure and 

Leddar range finder.
Draganfly Innovations Inc. www.draganfly.com info@draganfly.com Page 4 

Method of Landing/Recovery 

VTOL, no external equipment required. Altitude control assisted by barometric pressure and 

Leddar range finder.

Navigation equipment/capability 

Operation within direct visual line of sight, control and command inputs giving by Pilot in 

 Command. Automated flight possible for limited range using Draganfly Surveyor software 

 using GPS and IMU data, PIC remains in control loop. 

Electronic Surveillance Equipment 

UAV system has no electronic surveillance equipment. 

Flight Sensors 

- 3 axis accelerometer 

- 3 gyro 

- 3 axis magnetometer 

- GPS (position and altitude) 

- Barometric pressure 

- Leddar LED range sensor 

Redundant Systems 

Redundant power system, failure of a single battery or battery connection will still have 

adequate power for normal operations

Visual Detectability 

 

High visibility 40lmluminious flux navigation lights following standard marking colors. 

Optional high visibility paint scheme using day-glow and/or high contrast colors 

Control Methods and Failsafe 

During operation there is always pilot in the loop regardless of flight mode. Available flight 

modes are manual flight, GPS position hold and preprogrammed automatic flight using 

Surveyor mapping software. Failsafe is user adjustable before flight as either land 

immediately or return to base, this is triggered by a loss of control communication signal 

between the controller and UAV. 

Flight Instrumentation 

The following real time flight data is presented on a sunlight readable display on the ground 

station. 

- UAV battery voltage 

- Control station battery voltage 

- Control communication signal strength 

- GPS position and altitude 

- GPS signal strength, accuracy and position errors 

- Aircraft heading and bearing 
Draganfly Innovations Inc. www.draganfly.com info@draganfly.com Page 5 

- Aircraft altitude (AGL an ASL) 

- Aircraft horizontal and vertical velocity 

- Aircraft attitude 

- Flight time 

- Current time 

- Aircraft internal system temperature 

- Current throttle position 

- System alarms and messages 

- Flight time and mission time remaining 

Systems diagnostic and monitoring information 

System messages and alarms for changes in the operating status, system failures and flight 

conditions are presented to the operator by visual messages on a sunlight readable display 

screen and through audio alarms. Alarms and system messages include but are not limited 

to: 

 

- Aircraft low battery voltage 

- Controller low battery voltage 

- Weak or degraded communication signal 

- System failures and alarms 

- Acquisition or loss of GPS lock 

- Indicators for flight conditions and settings (motor engages, landing initiated, position hold 

engaged, etc.) 

Environmental warnings 

 

The UAV system does not have an integrated weather station or environmental detection 

 equipment. Environmental and weather conditions are to be observed by the operator to 

 ensure compliance with the following limitations and warnings. 

- Maximum wind speed for operation is 35km/hr, do not operate in wind exceeding this 

- Do not operate in conditions where precipitation is forecast or may be present. 

- Do not operate in conditions where any known form of atmospheric icing is forecast or may 

be present 

- Do not operate in environmental or weather conditions that may exceed the specified 

operating limitations. 

- Do not operate within 100 meters of active power lines, electrical substations or similar 

structures. 

- Do not operate in areas where HIRF may be present 

Control Station power source 

 For Hand Held Controller (all build revisions) 

 

 3 cell 11.1 Volt 1350mAh internal rechargeable lithium polymer battery. 

 

 For GCS controller (all build revisions) 

 4 cell 14.8 Volt 2700mAh internal rechargeable lithium polymer battery.

Equipment in control station 

Control station has integrated sunlight readable display screen which is illuminated for 

night operations. 

 

Command and Control links 

North America: 

 Control comms 

 Operating frequency: 902 to 928 MHz 

 Transmit power: 250mW 

 RF Data rate: 200kb/s 

 Range: up to 2 km 

 Frequency hopping spread spectrum 

 International: 

 Control comms 

 Operating frequency: ISM 2.4GHz 

 Transmit power: 63mW 

 RF Data rate: 250kb/s 

 Range: up to 1 km 

 Direct sequence spread spectrum 

Both North American and International data packets sent to the aircraft are encrypted and 

the aircraft will only accept command signals issued from the MAC address of the control 

station. Neither system has redundancy on the communication signal. 

Lost link indications 

The control station displays a real time indicator the communication signal strength, if the 

communication signal becomes degraded or lost a visual and audible alarm will be presented 

on the control station. 

Payload 

Only the listed permissible payloads may be used on the UAV system. None of the 

permissible payloads are dangerous goods or include items such as explosive, lasers or 

pesticides. None of the permissible payloads have secondary purposes intended for 

navigation or flight decision making and control.
