Control brushless motors "YGE 4S" for receiver AR6400
Be interesting control brushless motors "YGE 4S" for receiver AR6400.
His weight without wires - 0.6 grams.
I wonder what the output resistance he has?
Can he be the alternative to the widely ubiquitous XP-3A and XP-7A with too much loss of output impedance?
Its price is approximately equal to the price leader, quality- TMM 0703-3 EXPERT
But it is easier for it twice and resolved the problem with micro-connector.
Regulator "YGE 4S" really can buy here -

I think BSD has some of these coming. I'm planning to get a couple when he gets them. I always thought the YGE was the best micro BL controller.

Yep, YGE are the best in my opinion. After all the wasted time and missed flight time due to failures/problems with the HK esc's I will never buy them again. Last straw was KIEF, only had one good flight all weekend with my F-84 due to a HK esc. All 5 YGEs I've bought over the years still work flawlessly.

Yes, powered by 2S perhaps, judging from data on the controller:
Max # 4A continuous current, in with good cooling airflow.
# 1 to 2s LiPo with automatic detection of cell number reduction at low voltage.
# Undervoltage disabled.
# Speed control (Governor Mode)
# Soft start individually adjustable.
# Emf brake in 3 steps.
# Frequency of 8 to 16 kHz
# Rpm limit: 240,000 rpm (2 Poles)
# Dimensions: 11.5 x 17 x 3.5 mm
# Weight 0.6 g without cable
# Programming with the ProgCARD II

It is 2 cell capable but does not have a bec. Voltage to the rx and servos is the battery voltage. So, for the AR6400, it's a one cell esc.

Comparative tests of the regulator YGY-4S for losses on the output resistance, I spent a measurement of static thrust of different regulators.
The controller connected to the AR6400 receiver and brushless motor MM-13/3/12T (http://www.bsdmicrorc.com/index.php?productID=840).
Handle "gas" the transmitter to the maximum position.
On the motor shaft set screw (160 x 70) from the micro-aircraft SU-26m.
Supply voltage 3.7-Volt.
The static thrust with a regulator YGE-4S (weight- 0,6 gr.) amounted to - 67 grams.
For comparison quote the results with other regulators.
The static thrust with a regulator TMM-0703-3 (weight- 1,1 gr.) (http://mgm-compro.com/index.php?tid=...-0703-3-expert) amounted to- 68 gr.
Since the regulator MBC-3 MicroInvent (weight- 0,22 gr.!) (http://www.microinvent.com/mambo/ind...d=23&Itemid=42) amounted to - 61 gr.
Since the regulator XP-5A Micron Radio Control (weight- 0,8 gr.) amounted to - 58 gr.
Since the regulator XP-7A (weight- 1,58 gr.) amounted to - 52 gr.
With the regulator XP-3A (weight- 0,4 gr.) amounted to - 52 gr.
1. Controller YGE-4S "won" controlers XP-7A and XP-3A at 15 grams thrust (approximately 30 %)!!!
2. Controller YGE-4S practically not inferior traction best controller TMM-0703-3 and in this case has is two times less weight and the presence of connectors for connecting to the receiver AR6400!

The currents through the transistor switches
regulators will cause the loss 0,5 Volt -
at a voltage 7,4 V loss would amount- 6,75%;
at a voltage 3,7 V loss would amount -13,5%.
Than lower supply voltage, the greater will be the loss of energy, with the same elemental base ESC regulators.
With a low supply voltage (3.7 V) absolutely impossible to save on quality ESC regulator!

The old YGE-4 was capable of 1, 2 or 3 LiPo cells, and It had BEC.
I'm currently using one with a Spektrum ar6400, adding a silicon rectifier diode (1N4000) between the ESC and the Rx.
So the new YGE-4S cannot accept a 3S battery pack, and does not have BEC??? I don't know of a single receiver that can accept an 11.1 vdc supply voltage!!
|Apr 15, 2010, 12:24 AM|
Yes, the controller YGE-4S no has BEC and can not solve the problem of power AR6400 receiver on the voltage over 1S.
But for micro - aircraft weight category up to 50 grams, the use of LiPo 2S and 3S is a necessary measure to achieve the required thrust, more than 50 grams.
But this option the weight of the aircraft did not get the minimum possible.
The second (better) way is the use of low-Voltage power supply (1S) the use of efficient brushless motors and ESC controls.
Therefore, YGE-4S is the uncompromising choice in achieving maximum traction motor at minimum weight of the aircraft!
Examples of effective brushless motors powered by LiPo 1S (by 3,5 V) using YGE-4S.
1. Thrust 67 gr. - motor MM 13/3/12 (weight 5 gr) http://www.bsdmicrorc.com/index.php?productID=840

Thanks Vladimir for these informations.
I've ordered one for a single cell micro edf jet project.
I've seen that there is a programming card, but i hope it can be configured by mean of the transmitter....
