what connectors do i need to purchse to connect to motor and lipo, link me please

trivial pursuit (32%)
ESC to motor, can use 3mm or 3.5mm bullets. ESC to battery, and use dean (T style) or simular

montcop (46%)
Look at the sticker you have - on 1 side it for lipo you need put connector here like xt60. And 3 different color from other side it for motor. Link it with any combination and you can change rottation
direction by swap any two wires

Can i use this to replace my esky 30amp esc on my belt cp heli?? It looks identical. I dont want to go with the bulky heavy 40 amp esc i want to go as light as possible.

raz54 (54%)
That's an awesome ESC and would work fine as long as your amp load is under 25 amps.

Emilio (50%)
I think If you use 30 amp you must use 30 amp not 25 amp

ipin17_aero (63%)
No, for esky belt cp you better use 30A or higher ESC

How to set brakes? (10. the brake is seeing as default set
11. Reset the brake operation to release the brake function)
i do as the manual says,but i never get brakes.

Emilio (50%)
you swich on the rx,and give max throttle after connect rx and wait 10 sec after give min throttle and the brake is on

When i connect my esc it just beeps continuously. My battery is a 3s 1300mah full charged, my rx works. The esc moves the servos fine but doesn't power the motor. IT doesn't even allow me to access the programming features. Any help would be great.

Such Is Life (44%)
Mine does this sometimes, it indicates either you have a ***r initial connection with the battery (low voltage, check connector is completely together), the esc is on the wrong channel or your reciever isn't on / bound properly. Keep trying and you'll get it.

Such Is Life (44%)
Sounds like a motor wire is disconnected, or motor could be burnt out.

Wes1 (72%)
The continuous beeping is telling you that the ESC does not feel that the motor is connected.
Double check all wiring, bullet connectors, and solder joints. you may have a bullet connector that is just a bit too loose as for as fit, you may have trouble lurking under a heat shrunk connection (broken wire or fractured solder joint and a OHM meter may not find these unless the break is total.

Hope this gives you some direction.. Good Luck.

What is the difference between the 'H' and 'W' series for this esc? I bought 1 of these about a month ago and 2 more just last week. The one from a month ago has a green 'H' stamp on the back and the two from last week have a red 'W' stamp on the back. I am trying to use all 3 on a tricopter, however the one with the 'H' stamp will not arm properly while the two newer ones with 'W' stamps seem to work just fine. Any suggestions?

krall (50%)
H is a newer firmware version

The majority of the time I plug the battery (2S or 3S doesnt matter) into the ESC, the beeps are really soft. Then if i unplug the battery and replug without changing anything else the beeps will be normal (loud) again. This happens intermittently and I cant find a pattern. Any ideas what could be wrong? I have double checked all my soldering and it all looks ok.

Thanks

Watto (58%)
Well, the beeps are made by the motor (ESC uses it as a rudimentry speaker), so the position of the motor (how far it's rotated) could affect the volume.

power issues with my 64mm EDF F 117.
airplane will take off and fly for 2 minutes and land under powered.

3 chnnel 64mm EDF

-1500 3 cell 20-30c battery (tested fine)
-tower Pro w 25w (max33a)speed controler
-64mm EDF with electrify ammo 20-40-4850kv
any ideas ?

mzfckr (30%)
maybe because it drains the battery and at the end of the flight theres not enough power left?

shannon (50%)
Is it the motor timing on the speed control?

Wes1 (72%)
If you don't own a watt meter I would recommend you get one and put it in line. If the motor numbers mean what I think then the motor is capable of pulling up to 40C max ?peak. If you are at full throttle then that is going to be hitting the ESC and battery very hard which will equal the loss in power.
You need the meter to know for sure.

when im using this esc, the throttle is always on the wrong channel(stick). when i use turnigy esc everything is fine. how can i fix this?Is it esc's fault?

Moparman77 (63%)
No, the ESC has nothing to do with what channel you're on, it's the connection to the receiver.

mzfckr (30%)
strange, because with any other esc everythings fine.

Thank you Martin, but can you also please tell me how I set it to 3S lipo? Sorry for being noobish, but I'm prety fresh to this x).

Martin SK (75%)
It isnt problem with 3S LiPo if you have set the ESC in LiPo mode (see upper how to do it). Problem may by if you won use 2S LiPo. BTW if is problem with just charged 2S LiPo in LiPo mode ESC, tou can tray folloving:
1.)plug in to the balancing connector of battery some car bulblamp (50-60W/12V) - to down voltage in the moment of plugging battery to ESC
2.) plug in the ESC
3.) wait, until ESC beep number of cells
4.) unplugg consumption "hardware" from balancing conector

Martin SK (75%)
I had problem with 2 bougth ESC if I used 2S LiPo = after 1/4throttle motor always cuttoff.
If you wan use 2S Lipo with ESC MAG8 (25A) make folowed:
Set ESC to NiMh/NiCd battery
Why? If you plug fresh charged 2S LiPo, it have output voltage nearly 8,4V. 8,4V = 7cell NiMh/NiCd. Cutt off voltage protection for NiMh/NiCd is 0,8x7(cell)=5,6V (2,8V/cell) and its better protection then original setting for LiPo mode = 5,4V !!! For good cut off voltage protection is nessesery always used fresh charget battery!!! If you use 3S LiPo, set ESC to LiPo mode, with 3s ist problem.

Hey.. I bought theese 40-50amp hobbyking speed controllers b4, but I don't understand how to use them, bcuse I have to programate em b4 I can use it, so I wonder. Do I have to programate this speed controller b4 I use it, or can I just plug it and start flying? Hope any 1 can help me=)!

Sachin (57%)
just plug in and start, after putting the power it will beep 2-3 times for checking and then will beep long which means go.

when I powered up with 3 cell battery I get a constant beeping sound instruction says high or low voltage I checked voltage is ok tried several batteries anyy ideas??

Beaufighter (-25%)
Yes:) Try plugging in the rx plug the other way, you have most likely plugged it wrong.

Hieliew (34%)
I had the same problem, and wasn't plugged in wrong. It stopped beeping when I changed the throttle trim, so you could try that.

01raptorguy (75%)
I am having the same problem 3 beebs then constant beebs. I have tried all of the above any other ideas?

Setting Method:
Arm the transmitter, switch throttle stick to the full power position (for FUTABA series transmitter, the throttle stick shall be switched to REV).
Connect the receiver and motor.
Connect the power to the speed controller.
4�D If the transmitter is in normal condition, it will have the following sound: (if there are no more sounds after a long low sound at the end of this sound, check the reverse setting of the transmitter throttle channel).
�� B: indicates LIPO automatic protection
�� BB BB: indicates NiMH/NiCD automatic protection
�� BBB BBB: indicates brake selection
5. If there is setting you want in the process of sound cycle, switch the throttle stick, to the lowest position at the first time interval. (For example, select LIPO automatic protection: switch the throttle stick to the lowest position when hearing one B sound)
6. If there is another additional setting, quickly switch the gun to the highest position to make a selection.
7. If you have finished the setting you require, wait 2 seconds and the motor will send a confirmation sound for battery protection. It is usable after confirming the position of throttle stick.
8. LIPO automatic protection has only 2 voltage protection points, i.e 6V and 9V. There is no need to use a full capacity battery.
9. NiMH automatic protection is calculated according to the real number of batteries. Sets 0.8V for each battery. In order to ensure accurate judgment of the battery voltage, please charge the battery to full capacity. If the battery is not at full capacity. The speed controller will estimate the protection voltage according to 53% of the full capacity.
10. the brake is seeing as default set
11. Reset the brake operation to release the brake function. .
12. Factory parameter reset function: because this series of electronic governor has an overheating and false operation protective function, if you find that the speed controller is accelerating or changing is direction, or the throttle is different from the original condition, you can reset the factory parameters to obtain the highest performance.
When starting the machine there is a long B sound. It indicates that the electronic governor is in LIPO protection mode. The BBB sound indicates that it is in NiMH/NiCD automatic protection mode.

CAN I PROGRAM THIS ESC WITH TURNIGY PROGRAMING CARD?

Rosalind (46%)
yes you can use the turnigy prograing card.I used it and it worked fine.

angel (60%)
Can I use this ESC with LIFEPO batteries???

Andrey (82%)
Hello. How to program Timing on this ESC?

shannon (50%)
During programing find the timing mode ,
long beep then short beep, then it changes too a differemt set of beeps.
1 beep is slow or normal mode, 2 beeps is med mode , and 3 beeps is fast.

britinoz (64%)
Any one know if this unit can be programmed with a Turnigy card

Jacek (29%)
Yes, It is compatible with Turnigy card :)

William (31%)
1. Does it automatically detect 2 cells and 3 cells LiPo batteries?2. I lost my programming instruction sheet. Is there a electronic or online copy somewhere?

harry (59%)
yeah, it automatically detect 2 cells and 3 cells and make one beep per cell, so you are sure that it has well detected the number of cells. Then it makes a long beep which means all is ok

Rush! (62%)
oh. ok. thanks :D not good. need brake off....

Rush! (62%)
Can you disable braking slection to off? it only has two options (soft/hard) listed on the specifications. Thanks
