Summary
CineLog25 will be available in three versions: CineLog25 HD PRO, CineLog25 HD Micro, CineLog25
Analog.
The most noteworthy feature of CineLog25 is the lightweight quadcopter that can be shoot video
by GoPro Lite. It adopts the most popular backward push design on the FPV field at present. It
can effectively use the thrust weight ratio of propeller to obtain higher flight efficiency. In the
overall layout of the drone, we put VISTA HD in the center of the quadcopter, so that the center
of gravity of the quadcopter is in the middle, The propeller Inlet is smoother and the noise is
lower. Redesigned the shock absorption structure of the camera mount and GoPro Lite,
Eliminated the jelly of the camera and FPV camera, and we can use 3, 4 and 5 damping rings
according to the flight state to obtain the best stability in vibration and noise.
The F411-20A-F4 AIO and GEPRC NEW 1204 3750KV motors are used in flight system and power
system. The power battery can be compatible with 450mah ~ 750mah.
The flight time of CineLog25 is around 5.5 minutes (it depends on the flying habits). The stable
electronic equipment and advanced frame materials make the quadcopter stable and can achieve
all FPV freestyle tricks easily. The customized EVA protective foam cushioning around the frame is
more elastic and can effectively protect the fuselage while crash happening!

Feature
1.New camera damping system
The New camera damping system basically eliminates the video’s jelly and FPV camera’s
vibration in terms of designing, The damping construction can be adjusted the harder or
softer to suit the Flight State. There are Three, Four and Five damping rings can be used to
provide sufficient stability in vibration and noise.
2.Brand-new exclusive pusher frame
The CineLog Whoop Quadcopter adopts a brand-new stunning pusher frame design,
Including ultra-light carbon plate and new material, strength increases by 20%, efficiency
increased by 15%
3.Low noise optimization
Cinelog Whoop Quadcopter Increases the Air Inlet volume and it with the EVA foam
cushioning,Reduce the Airflow Resistance in order to create extremely low flight noise and
greater reduction of noise from external vibrations
4.Long range flight
High efficiency power matching, The latest GEP 1204 motor power output scheme and
Brilliant Tune have further Improved the flight time
5.Low center of gravity design
The CADDX VISTA was placed at the bottom, Optimized Design for the Air Inlet Structure.
It’s a point of the greatest importance is a low center of gravity “pusher-style” inverted
frame, increased efficiency at least 15%
6.Perfectly Compatible with most of mainstream cameras
Compatible with SMO 4K, Gopro6 lite and Gopro8 Lite (coming soon),etc…
7.Using DJI HD Goggles
Vista
10.Optimized bot Nebula Pro (120 FPS HD camera, 28ms low delay flight)
8.Adjustable lens angle
The flight angle of 0-40 degrees can be adjusted according to the flight requirements, The
camera’s angle can be adjusted to meet your variety of Shooting needs
9.With EVA foam cushioning
Integrated EVA design, the overall shape look more coordinated, better strength.tom design
The bottom part increases the strength of landing and perfectly protects all electronic
equipment
11.Camera power line output
With its own power cable output to the camera (Gopro6 & Gopro8), It has its own Video
Recording Wire,The camera can be turned off or on directly Via Remote controller

Bind with Air Unit
If you buy cinelog25 PNP (DJI receiver), You need to pair with DJI remote control and DJI
Goggle ,The Cinelog25 HD is ready to fly.
The bind sequence must be DJI Goggle first, and then DJI remote control. If the bind sequence is
wrong, Otherwise the Air Unit will disconnect from the remote control, The remote control
should be rebind.
Note: in order to ensure safety, the propellers must be removed before frequency matching.

ARM Switch
Two Required Conditions before Arm
Low Throttle
Arm Switch should be put into unlocking mode
When unlocking, the throttle must be
pulled to the lowest position, otherwise,
when the unlocking switch is turned, the
motor will not have any action. If the
buzzer is installed, a warning sound will
be launch, indicating that the throttle
lever is not in the lowest position.
When landing, when the height drops to
about 30cm from the ground, it can be
locked to complete the landing

Modes Switch
There are three Flight mode in CineLog 25 HD
ARM
ANGLE
HORIZON
If you are novice, Recommend Angle
Mode, Easy to control.
ARM
The main feature of Arm mode is that the FPV attitude will not keep horizontal automatically.
Must rely on the pilot's fingers and experience to maintain balance, It can perform a series of
difficult Freestyle movements.
FPV in Arm mode has great flexibility, but it is difficult for novices to control at the beginning.
ANGLE
The biggest feature of Angle mode is that when the stick returns to the middle position, the FPV
will automatically return to the horizontal state and hover, which limits the tilt angle of the FPV.
The Angle mode reduces the difficulty of operation and is friendly to novice.
HORIZON
The biggest difference between horizon mode and angle mode is that based on angle mode,
horizon mode without angle limit. It can fly faster and more flexible than angle mode
