Just have made a mod soldering a pigtail for external antenna. Great!
I have immediately tested it on a 2S custom designed and 3D printed brushed micro fpv racer quad and it performed great! https://vimeo.com/221064567 The quad became a bit too heavy with the additional 6g weight and also needs some fine tuning on the PID's since I have put it on. The DTX03 picture quality is great, it doesn't have any flashes, stripes or noise. The audio quality is also great! Finally I can hear the motors for proper PID tuning and also it is more fun to watch the recorded videos back. This transmitter can become super hot in short time so avoid leaving it powered for longer time mainly on 200mW! The switchable 0, 25, 50, 200mW power is working properly. I could feel range differences between the settings. Also I have found no shadowing to other channels so I could see the picture only at the channel where I set the vtx to. I have uploaded some photos to see how it could fit on my quad. I could put it only on the top plate. The final conclusion is that this is a very nice product and is required for most micro users but on 1S coreless I think it will make the quad overweighted and will loose flyability, on 2S coreless it is flyable but the quad looses agility and also flight time reduced from 5 to 3 minutes on 50mW. Also take proper check on your 5V regulator as this can take a massive amount of power and can put your drone to failsafe or reboot in the air. From my 1 day experience I think this is mostly suitable for at least 2S brushless micro drone.
Switchable VTX with DVR for this price is very interesting. My full review is here: https://www.rcgroups.com/forums/showthread.php?2889805-Review-of-Eachine-DTX03-5-8G-72CH-Switchable-VTX-w-Audio-DVR
Es ist nicht AIO-Kamera, nur Sender und Rekorder, was ziemlich gut ist, weil Sie jede Kamera wählen können, die Sie wollen.
Dies ist meine zweite Einheit und ich muss sie gut funktionieren! Meine erste Einheit wird als Repeater für mein 1,3 GHz Videosystem verwendet. Mit dieser verkabelt in die Videoleitung nur kann ich das Signal in 5.8 Video für diejenigen, die das Flugvideo sehen wollen, aber nicht über eine 1.3ghz vrx. Das große Plus an diesem vtx ist die Tatsache, dass es einen micro sdcard Steckplatz hat, und es ist umschaltbar von 25mW bis 200mW. Perfekt für einen micro fpv Flügel oder bauen. Ich werde auch die Antenne austauschen für etwas ein wenig besser, aber für zukünftige Referenz ein ipex oder Mmcx Stecker wäre sehr zu schätzen, da ihre eine Vielzahl von geeigneten Antennen, die dieses kleine vtx verbessern würde
Quite impressive ,This little unit gives out a very clear picture and noise free, and is small enough to mount on most quadcopters for FPV filming. The setting up was difficult, beware of instruction wiring, it shows usual video colours, yellow, red and black, but in the instructions shows different colours. The Banggood images provided above show the correct wiring. Luckily, for me, and probably others , it seems even if you wire it up wrong with these 3 wires , it wont damage the unit ! This item does need Class 10 SD card to work, otherwise the indicator LED will just stay Solid ON rather than flash showing that recording is in progress. It also runs hot (uses almost 1Amp power on the 200mw setting, check your power supply can cope ! ) , Ive refrained from covering this in heat shrink to allow better cooling, and mounted it with free air flow. To get the on screen set up display, the red and black of the x3 wire harness need connecting to a Screen via cable not VTX. this is awkward. Considering the size, price and image quality i rate this unit highly although clearly there are plenty improvements possible
I use it for a 220 quad, It is light and with 200 mW it has a range of about 700 metres. It works properly and without delay because the video signal is sent to the transmitter before sending it to the DVR. I usually modified it with a piece of coaxial cable of 4 cm to elevate the four lobe antenna and get more range. Be careful that there is no video camera in the unit.
Gut verpackt. Lieferzeit etwas über einer Woche. Muss noch getestet werden.
Alles läuft so, wie ich es erwartet habe.
Köszönöm. Rendben megérkezett. Sajnos a kamerának nem ad ki megfelelő Voltot, így azt külön kell táplálni.
