BK Controller set up problem

I've got a brushless revo but I'm having trouble programming the BK controller that came with it. I've followed the steps that I found here at rc-monster but I still can't seem to get it to work properly.

I've done the set up for it step-by-step but when I try to drive it it still kinda just jumps and sputters (does that make sense?) ..it won't go full throttle.

Anyone have any suggestions?

ok, well I just noticed the red programming bridge has come unsoldered. Can I just solder it back on?

Yes. I had to do it on a few of my BKs.

I'm still getting that stuttering thing happening when I give it full throttle. I've re-programmed it several times now but it keeps doing it.

Anyone have any ideas as to what I can do to fix it. I've had this truck now for about a month and I would really like to get it out and run it

Thanks

What motor are you running? The BK controllers only like the 2 pole motors like the Feiago, Lehner, Hacker. It wont run well with a Neu or Mega or any other motor that is more than 2 poles.

If you have one of the high amp models, the rpm limit is only 42000rpm.

It sounds like everything is working OK, and the setup sounds right. Other things to look at:

- Are your batteries up to the task? Weaker/tired cells won't be able to deliver the current required.

- Are the connectors (power and motor) dirty, loose, or soldered badly? Those won't pass the current effectively and will also cause voltage drops.

Did the previous owner stick it in a blender?

Nice repair job Arthur

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.
