I have bench tested TX526, which I received from Banggood. Link to this video transmiter:
http://www.banggood.com/Eachine-ET52...ampaign=montis

This VTX has 4 power levels: 0 mW 25 mW 200mW 600mW, 5 bands: A b E F r, 40 Channels total.
Weight is 7.1grams, exactly the same as TX5828. Size is almost the same as other similar VTXes:



Changing of the settings can be easily done with just one button. Short press of the button to change channel, longer press (2sec) for changing band and long press (5sec) for power level selection.

It has RP-SMA antenna plug, despite some misleading information on the user manual leaflet.

Cable is 5-pin JST-SH 1.0mm one. The same cable and pinout fits TX5828 transmitter.

I have received DYS 2830 1300kv motor from Banggood recently. I want to share my thoughts and test data of this motor.

Motor quality is very good. Feels solid and well-made. I have tested it with 3S and 4S with 8040, 8040E and 9060E props. Got good results with 3S battery, but my tested propellers were too big for 4S battery - motor gets too hot. So I quess that 7 inch sized propellers should be OK with 4S battery.

Note: If you decide to cut the shaft, then I advice to put motor into some plastic bag while cutting. This will prevent metal grinding particles from getting inside the motor (thanks to Mike Dubovsky for this tip!).

Tested props:
* GWS style 8040 prop
* APC style Gemfan 8040 (8x4)high efficiency propeller (you can find this propeller here: https://goo.gl/PeBem1)
* APC style Gemfan 9060 (9x6E) high efficiency propeller (you can find this propeller here: https://goo.gl/eho4v8)

APC style 8040 sized propeller is too big for 4S - motor gets too hot while testing. I suggest to use smaller than 8040 sized propeller for 4S battery.

DYS D2830 motor thrust test (1 min 40 sec)


Thrust test result sheet: https://docs.google.com/spreadsheets...96&single=true

Unfortunately I dont have RPM meter (yet), so no RPM data.

Good:
+ Well-made motor
+ 3.5mm bullet connectors presoldered
+ Silicone wires (wires inside tubes)
+ Good thrust results
+ Best price

Bad:
- Shaft is too long
- No label with size and kv on the motor

Bottom line:
Besides some minor issues, this is very good motor for medium sized planes. Provides more than 1Kg of thrust with Gemfan 9x6E high efficiency propeller (you can find this propeller here: https://goo.gl/eho4v8 ). Look at this thrust test at 4:55 of this video.

Motors are packed in red carton box with bubble wrap and 4 pcs of M2 screws. Motors have nice red Racerstar color, not some boring black color like others. I like this exceptional color a lot.

It happened so, that one of the received motors didnt have a washer (brass spacer) between the bearing and a c-clip. Someone at the factory forgot to put it on. This particular motor has some significant vertical play, you can move the rotor 1mm up and down

I plan to:
1. Solder an external sonnector for camera and power. Some switching regulator can be seen on the pictures, so maybe higher voltage tollerant? We'll see.
2. Upgrade this VTX to 200mW(250mW?) version. Here is a walkera forum where a simple upgrade process is shown: https://walkera-fans.de/runner-250-t...17-ce-umbauen/

Ordered a few. Waiting impatiently.
