I have recently received a set of Racerstar RF2205 2300Kv motors from Banggood for a review. Motors came well packed in a carton box. Package includes motors, bullet type prop nuts and M3 steel screws. Motors are sold only in packs by 4 (2 CW + 2CCW). It would be great if Racerstar would offer an option to buy single motor. This will enable buying a spare one or a replacement for broken/bent/burnt motor. Personally I would suggest to sell only CW shaft thread version of these motors with a prop lock nuts. Lock nuts hold props hard enough on CW and CCW rotation motors there is no real need of different threads. Benefit of this is versatility of motor use – every motor can be either CW either CCW, no need to have 2 spares and in case of RF2205 - 4 spares.

Comes in packs by four

Motors have solid hard steel shaft. That is one of the reasons why they are heavier than BR2205.

This is my humble review of the Eachine ET526 VTX transmitter
http://www.banggood.com/Eachine-ET52...ampaign=montis

This VTX has 4 power levels: 0 mW – 25 mW – 200mW – 600mW, 5 bands: A – B– C – D – E, 40 channels total.
Weight is 8.5 grams. This is slightly more than typical VTX weights and this is mainly because of the heat sink attached. Size is almost the same as other similar VTX‘es:



First interesting feature is Transmitting Power OFF on startup. Every time you power this VTX, it starts with TX power OFF (TX led is dim). You have to double click upper button after you power up the VTX to turn video transmission on.
Second interesting feature is on-board microphone, which can be turned ON and OFF
Changing of the channels and bands is done with lower button pressing. Short press of the button to change channel, longer press (2sec) for changing band and long press (5sec) for on-board microphone On/Off.
Double click of the upper button turns the video transmitting on. Longer press (3sec) changes power level selection 25 – 200 – 600 mW.
Cable is 6-pin JST-SH 1.25mm one. Cable has a 3-pin camera connector on another end of the cable, also female servo connector for Power in (7-24V) and female servo connector for PWM input. Camera connector compatible with Eachine 1000TVL CCD camera.
Antenna connector is SMA type. This is good for VAS/Fatshark users as their antennas have SMA connectors. Others can use SMA->RP-SMA type changing adapter (like this one: ...Continue Reading

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 VTX‘es:



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.
