BK Controller set up problem

[krunk]

Artur, Great job with evader's ESC.
Hopefully you can help me too. I have a 15020 that is cogging horribly. I have tried everything in thread with no help. It also does something wierd. If I remove the BEC (black jumper) the ESC does not work at all. Have you ever had that problem?

What are you using to power the reciever when you disable the BEC ? Perhaps your UBEC or RX pack is not supplying power correctly to the RX ?

PM sent.

I will check for 5-6V at red wire on ESC's interface cable. If you do not have correct voltage here then ESC would be in Off state.

To all:

Thank you for comments,

I received my stuff back from GriffinRU on Monday and it looks great...looks brand new!!

I am still having a problem programming it though. I follow the steps for programming it that I found on this site. I pull the red jumper off and then plug the batteries in. After 5 seconds it beeps and I'm supossed to give it full throttle and then it's supossed to beep again then I'm supossed to give it full reverse and it beeps again. Well it beeps the first time after I plug in the batteries but after I give it full throttle it doesn't beep or do anything at all.
Even when I hook up the batteries without taking the red jumper off it beeps like it's in programming mode.
It's probably something simple that I'm doing or not doing but I can't figure it out...can anyone help me? I was hoping to get it to the track tonight to get it set up for our club race on Sunday.

Thanks

Can you publish a picture of your setup-testing?
If I remember correct BK-Electronics ESC's were sensative to TX channel polarity, can you reverse it?

Ok, so I figured out that it wouldn't program until I reversed the direction of the throttle on my radio. So now it will go through all the steps of programming...however it keeps going through those steps now. What I mean is even if I don't take the "little red jumper" off to program it it is always in the programming mode (even when the "little red jumper" is still on). What the heck is going on??? Am I missing something?

Here's some pictures.

Good, I was correct on channel polarity.
Next step, why you are still in programming mode?
-Check if red jumper actually shorting two pins together, sometimes metal clip inside jumper falls out.
-Make sure that you turn power off after you put jumper back on, not oppoiste.
-Cross your fingers :)

Have you tried a receiver pack yet? I have also heard BK's prefer 5v over 6v. What is your ubec running at?

I soldered UBEC directly to ESC power plugs and disable internal BEC. BK ESC prefers 5v only when internal BEK is not disabled, I cannot see any component inside which would cost a grif at 6v. Let me know if I am missing something.

it doesn't appear that the 2 pins are touching each other or anything like that.

I don't understand what is wrong with it when it worked for you when you tested it?

Just to make sure I have everything plugged in properly...the steering servo plugs into spot 1 in my receiver, the ESC goes into spot 2 in the receiver and the UBEC goes into the battery spot...is that correct?
