My ESC overheated and sometimes would not throttle up after a short run.. $7.70 wasted

every time i move my throttle stick up this esc enters the programming mode Here imos what happens I connect the battery=> turn on the transmitter=>motor is giving a beep as usual => when i move the throttle up motor beeps the programming beep sequence.=>when I move the throttle to off position it is giving the normal confirmation beep=> after that 3 short beeps =>when i move the stick slowly up it repeats the same programming sequence again./turnoff the transmitter and come back same thing happens again.Please help!!!

I am using this ESC on my quad with Turnigy D2836/9 950KV Brushless Outrunner Motor ..... I am having KK2 board and the quad frame is Hobbyking X580 Glass Fiber Quadcopter Frame w/Camera Mount 585mm ... While tuning the PID values on board I found one of the motor starts a bit late, but as I move throttle more up all motors move with the same speed so I ignored this delay in start by one motor .... One more thing I want to mention here is that when I turned power ON ... only this motor/ESC give some different music first and after that all other 3 gives the same sound .... Now I am having problem in this motor .... This does not speedup with all the motors even moves very slow as compared to others on full throttle ... Please guide me, what to do

I have a problem with mine which I can't solve. I have 4 of these linked up to a i86 multirotor control board and an Orange rx R615. My tx is bound to the rx and I have a solid orange light to verify that, but my control board is flashing red slowly to indicate no signal (everything plugged in correctly) and I can't seem to see any problems except for these ESC's beeping twice every 4 to 5 seconds which I don't understand... Help me please D:

The orange light doesn't meen that your remote is connected infact it meens the rx has power but no signal if it is green it has both. Did you do an initial bind between the tx and rx as it says in the instructions?

Thanks but I actually got it working now...turns out I had bad servo leads. The rx doesn't have a green light BTW it just stays solid orange when connected and has no light when there is no signal :)

It is what it says - Super Simple
Here are the instructions:
Always start with throttle off, except when programming - then at full throttle!
Remember to check for channel reverse!
1. Turn on TX.
2. Set full throttle
3. wait for the beeps - 3sec after the first initial beep: (move throttle to off position during pause to select setting)
3a. beep, pause, beep - Li-po (cut-off 3v per cell)
3b. beep, beep, pause, beep, beep - Ni-Mh (cut-off at 60pcnt of starting voltage)
3c. beep,beep,beep, pause, beep, beep, beep -toggle brake enable/disable
Glad to have it, will by more. Cheers.

This ESC works perfect up to 30A. Nice linear throttle. But I WARN you now, I bought on Sept. 28, 2009 because I needed a 3A BEC. After testing it on my Watt Meter it only has a 2A BEC. It cuts off and resets at 1.89A using 6 HXT900 servos. Minus 1 for wrong Spec. Other than that, great bargain. Also vote plus1 on this review to let others know about this mistake. Thanks.

Tento regulator je opravdu SUPER. Bez velkeho programovani bezi s mnoha stridavymi motory. Plyn je linearni v celem rozsahu. Zkousel jsem ho s motory Mystery 2632-800 a 2930-1000 a s motory KD 22-20L a vzdy plny vykon bez probelmu. V teto cene se neda sehnat nic lepsiho. Neni k nemu navod, ale programovani je jednoduche: Jedno pipnuti - LiPol, dve pipnuti - Nixx, tri pipnuti - brzda. Programuje se stazenim plynu na minimum.

This is a no frills ESC that works great. I have tried it with both inrunner and out runner and both worked equally well. The programming is cell type and brake on/off. I have tried it with several Suppo outrunners and a 4100kv Himax ducted fan all run fine with this esc. Just cant beat the price on these!!!
