Mini-Review
AOMWAY HD518, 7" 1020x600 w/ diversity & builtin DVR (beta version)



EDIT: 01/01/16

There is known bug with NTSC cameras. With such camera, there is an horizontal offset. Main probably a firmware update will solve the problem


INTRODUCTION

After a serie of good FPV products, AOMWAY just announced a new 7" FPV monitor with a builtin 32CH 5.8G with diversity and builtin DVR. The HD518 is a direct competitor of the Boscam/Eachine 5802S


BOX CONTENT

+ 1 x AOMWAY HD518 (with a builtin 2200mAh)
+ 2 x 5.8G linear antennas (+5dBi)
+ 2 x AV/RCA to minijack cable
+ 1 x Sunshade
+ 1 x Velcro band
+ 1 x Instruction manual (English)

OVERVIEW


The full feature list is promising



As you can see, the diversity system have a sensitivity of -95dBm (per receiver ?) so one of the most performant in the market. The FPV part is recorded in D1 format. As for the RX004, two outputs are proposed + an AVin. The "mode" button cycles between these 3 options.The default first output named "RF" represents the direct FPV line without any preprocessing of the buitin Video core unit. This one must be used for FPV flights. The second named "DVR" represents the output of the VCU associated with the OSD/DVR. In practice, the frame rate of this channel dropped to approximatively 20 fps. The last "AVin" can display an external source.





The sunshade is a non-rigid model and have to be attached via the provided velcro band.




Notice, you have the holes to welcome an hard casing sunshade.

2 SMA connectors



On the left side, you can find the microSD card (up to 64GB microSD card) and the wheel controlling recording and OSD navigation



To simply record, just press on it. The same to stop recording and voilà ... I noticed sound is not recorded in AVI files while you can hear it through the speaker during the live session. Maybe it can be corrected by a future firmware.

If you long press on it, you enter in the OSD menu ( if you previously selected the "DVR" mode). In the menu you can replay recorded files in forward/backward direction at different speed.




FPV files are recorded at 42 fps in D1 format (720x576). I noticed also some problem of time-synchronization when the signal is absent (but without signal, it's rather hard to syncrhonize, it's obvious )



On the right side, the power input, an AVin and AVout (2.5mm jack connectors). What's a pity; no charger provided, only the power lead cable.



The "RF1" is associated with the right antenna and the red LED color while the "RF2" with the left antenna and the blue color. In Diversity mode "RF12", the LED cycles very fast between the red and the blue color.




The monitor uses a beautifull matte screen with a brightness of 500cd/m². Good news, no blue or black screen in low RSSI conditions.



The image quality is just great... The autosearch/freq scan is really efficient and select generally the correct frequency



If you press once on the "menu" button, basic informations are displayed: RSSI, band, freq and FPV battery level



The informations dissipear after 10s. There is actually no option to permanently display them (maybe in a future F/W release ?)

A lot of settings can be ajusted: brightness, contrast, color, volume, input (RF,DVR,AVin), RF sel (RF1, RF2, RF12), mode (16:9, 4:3), rotation (LD, RD, RU, LU) and language (English, chinese). So there are 4 différents way to rotate the screen, a very good feature when you have some constrainst in your FPV cam positionning. RF12 is nothing else than the diversity output. Another nice feature, when no signal is received, a beep is emitted after 1min.

UNBOXING

RX SENSITIVITY TESTING

AOMWAY HD518 RX sensitivity test (Courtesy Banggood) (10 min 23 sec)


The general RX sensitivity is just great. You can feel a real difference between a -90dBm and -95dBm system (in theory close to double the distance range. I know from a tchat with an AOMWAY contact, they got in lab a -99dBm model..... but too expensive to produce right now)

CONCLUSIONS

I will make short, I am totally and positively impressed by this FPV monitor. The generaly quality build is very good, a lot of nice features (rotations, sound alarm, etc.. are included) and the more important diversity RX sensitivity is just great as well as the quality of DVR recording. Almost the perfect FPV monitor. If you are hesitating with the Eachine monitor and you can afford the 30-40 dollars, go for this HD518



PROS

+ Superbe matte screen
+ 1024x600
+ Diversity
+ Great RX sensitivity
+ Great builtin DVR
+ 4 different rotations possible
+ Sound alarm when no signal is received
+ Playback functionalities
+ Builtin speaker

CONS

- NTSC display bug
- No battery charger included
- Sound not recorded
- OSD informations disapearing after 10s (RX RSSI, LiPo voltage)
- No race band support
- No USB port


This FPV monitor have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thanks them for this attitude.
You can find it actually for 140USD at http://www.banggood.com/AOMWAY-7-Inch-LCD-5_8G-32CH-Dual-Receiver-FPV-Monitor-DVR-with-Sunshade-Built-in-Battery-p-1012632.html

I found a Aomway site on the internet and wrote an email but no answer... I asked about a hard foldable sunshade... Perhaps you can ask your contact what about a hard foldable sunscreen, after all the mounting holes seems to be available on the screen... It will have also the advantage protecting the screen when not in use.

I just add this one to my wish list. I was going to buy the Eachine one come springtime but now I think I'm going to go with this one instead. Great review as always Seb.

One thing though, does this have any AV Out connections for using with goggles?

Edit: Never mind, I just read through it again and saw that it does.

Very keen from Aomway (without the need to see the batt. level) to warn with non irritating beep with really decent interval when battery get's empty. And after another 10minutes (just guessing) when the beeps comes at short intervals and becomes irritating then it's your own fault
When i had the beeps around every 10 or 15 seconds i powered it down and connected it to my laptop charger. I did forget to check how long it works on a full charge until the first beep and forgot to check the actual time between the first beep and the fast beeps but hey i like it, it's a usable function

As far as I am concerned, you are THE go- to guy for any kind of review. This was another outstanding, clear, and comprehensive review. Thanks.
I am very glad that a company picked up where the RC732-DVR left off. That divRxMonDVR used to be marketed by Bang Good, and is still by Gear Best, left off.
I own the RC732-DVR diversity monitor/DVR, and it has some production problems, but its automatic frequency scan, inclusion of the DVR and internal battery, on/off switch was ground breaking at the time I bought it in late 2104...
The Aomway model raises the bar by including all this, plus a much higher resolution screen with a matt surface to reduce reflections, multiple image rotation options, good receiver sensitivity, and from your information, reliable in/out ports that do not have to be reamed out to work.
If Aomway can replace the fabric sunshield with a foldable and strong plastic shield, include a recharger with options for USA,EU, and Australian plugs, and correct the inability to record audio on the DVR recordings, this will be a perfect ground station unit!

Would you recommend this over the Black Pearl monitor? I am contemplating to buy a screen with built in receiver after all, don't want to carry around so much electronics as screen + separate receiver. This seems like a more convenient solution with less cables.

Yes, with the integration of the monitor, let you save more attachment.

This thing seems to tick all the right boxes except... Why no foldable plastic sunscreen? It looks like they were contemplating having one as it appears that it has the cutouts on the front. That cloth "thing" really detracts from an otherwise very nice looking package.
