The Nazgul5 is a very good freestyle drone that flies smooth as butter with 4S or 6S battery. The Stack is with F4 FC and 45A ESC's. The video transmitter is 25-600mW and at the front is the good CADDX Ratel FPV camera. The iFlight Xing-E 2207 2750KV motors are great even though they are entry-level motors.

The iFlight Titan DC5 is a 5 inch FPV freestyle drone with 222mm. The special thing about the drone is that it has the DJI Air Unit and can be flown with the DJI Digital goggles. The video image is digitally transmitted at 720p 120 frames per second to the goggles. At the same time, the video can be recorded in HD with 1080p 60 frames per second on the drone on a micro SD card. So you really do not need a GoPro camera anymore.

Fatshark Byte Frost is the new digital system to transfer the video digital from the drone to the FPV goggles. Similar to DJI Digital FPV System.


Here is a base station consists of a 5 inch monitor and four antennas used. Via the white HDMI mini cable the video to the FPV goggles is digitally looped through. So you get a razor-sharp picture with low latency in the display's FPV glasses. As glasses you should best use the new Fatshark Dominator HDO 2 which has the native resolution of 1280x960 pixels. The new HDO 2 finally has a field of view of 46 degrees, which is even more than the ORCA FPV goggles, which is not yet on the market (November 2019). The OLED display's are significantly richer in contrast than the old HDO display's. Diopter lens attachments are no longer needed, because each optics of the HDO 2 is individually adjustable to one eye sharply adjustable from 0 to -6 dioptres.

Byte Frost firmware update:
1. On the SD card will copy the 3 files for RX so the 5 inch receiver BYTE_FROST.bin, HDZERO_RX.bin and HDZERO_VA.bin
2. The one file HDZERO_TX.bin for the transmitter unit is also copied to the SD card
3. SD card is inserted in RX the 5 inch receiver.
4. The firmware cable is connected to the transmitter (TX) and to the port at the back of the 5 inch receiver (RX)
5. The transmitter is connected to power (3S battery)
6. Now the 5 inch receiver is connected to the battery
7. The 5 inch display shows READ FILE and write BYTE_FROST.bin, write HDZERO_RX.bin,...Continue Reading

Xiaomi FIMI X8 SE 5KM 4K 3 axis gimbal
Banggood HK Warehous Coupon: BGFIMIX8SE10 https://www.banggood.com/custlink/Gmv3BGOgl0
Fast-29 EU Warehouse Gearbest Coupon: FASTGBFIMIX8 http://bit.ly/GbFiMiX8seEU
Coupon2: FIMIX8SE4K
This is the 4K version of Xiaomi Video drone which has real 3 axis stabilization and a 4K camera. The good thing is that the video image is transmitted digitally in HD live up to 5km. GPS with all the important functions like following, selfie gestures, flying around an object are included.

Xiaomi FIMI X8 SE Video Drohne - Review deutsch (7 min 41 sec)


I am excited about the video drone. A very good control to which an iPhone or Android mobile phone is connected. The app works very well. The most important feature I'm interested in is always the video quality and above all how well I can control the drone while filming without something in the picture jerky. Due to the slightly more weight of the FIMI the drone stays calm in the air. A wind does not bother here at all.
I find the camera guidance very good on the FIMI remote control. All panning and movements are very good straight away and the video looks every soft. Such a good quality I know only from DJI. Here Xiaomi shows that you can make even for less a perfect video drone.
The Xiaomi FIMI X8 SE is better than the DJI Sparks or DJI Mavic Air and comes close to the DJI Mavic Pro.

Pro:
- stabilized with 3 axis video camera
- Very good 4K camera
- Flight time over 32 minutes
- 5KM range
- very stable flight

cons:
- nothing

Eachine Cinecan 85mm 4K - CineWhoop - Banggood Coupon: BGWKcinecan


http://bit.ly/EaCineCam
This is the 85mm CineWhoop from Eachine with the good Caddx Tarsier that can record 4K, but more importantly that it has a very good FPV camera. The Cinecan flies well and is not as heavy as Beta85X 4K. The video footage is very good, but it shakes a bit, especially if you give too much throttle or it is windy outside. What I really like on the Eachine Cinecan is that it flies perfectly in Acro mode without a washout.

Pro:
- best FPV and HD 4K camera
- Very light as a 4K CineWhoop
- strong 1103 motors
- Video transmitter 25-200mW
- F4 FC with 10A ESC
- external receiver like CrossFire
- flies very well in Acro Mode
- ND8 filters

Cons:
- Video trembles
- not durable

With a flying weight of under 68 grams a big fun. The FPV Micro Racer is so great to fly. So far, I have had so much fun with only 5 inch racers, but never with a micro racer with a size of 105mm motor distance. Betaflight 4.0.2 is installed on the SailFly X. The throttle is limited to 75%. If the throttle is set to max. 75%, you have no more vibrations and the battery lasts longer. I've taken over the PID settings from the YouTube Albert Kim channel.
The flight behavior of the Micro is awesome. Fly perfectly with the original 3S 300mAh Lipo.

Video 1 – Happymodel Sailfly X Micro FPV Racing Drohne
Happymodel Sailfly X Micro FPV Racing Drohne (7 min 0 sec)


There are only two disadvantages of the SailFly-X and this is the D8 receiver loses the connection after 100 meters and the bad video antenna that does not reach more than 100 meters. I have already flown other racers with 25mW and they had better video channels or antennas and thus a better video reception. The D8 receiver can be replaced by a FrSky R-XSR or with FrSky XM receiver, then you have a perfect reception with 1 to 2 grams more weight. Then I would be at 70 grams takeoff weight. The SailFly is so durable I did not think so. I have repeatedly crashed on the hard ground and nothing. Only the propellers have bent. The propellers I could even turn back and fly on.

Last weekend I tested the iFlight CineBee 75HD at 1800 meters on the mountains. A very nice, tiny Cinematic Whoop.


The Caddx Turtle V2 camera even has the new Glass lens on it.

The freestyle frame is great. Especially the 2inch version fit on even the 2.5 inch Gemfan 2540 propellers.
Flies good with the battery on top with the Runcam Split mini 2. If you want better FPV video add a Runcam Racer 2 Camera as second camera on the top in a 3D printed case. This is my best HD mini quad, better as Beta85X or another micro drones.
The site with the 2.5inch propeller is the best solution for maximum power with the 1106 motors and 3S-4S Lipo 650-850mah.

I tested the X220HV - It flies very well. The motors are grandiose. The FPV video is very clear, if you mount the XT60 cable on the left side and disable the Speedybee Bluetooth module. Some reviewer say the ESC 4in1 board have connection issue with the FC board because the pins are too short.
My Eachine Wizard X220HV flies without problems. Very long with 4S LiPo and with many power with 6S Lipo
