bk 9920 problem... help needed before returning product...
 

hi all,
i just have bought a Feigao 9L + warrior 9920 controler, and I encounter problems with it...
I arrive to program correctly my controler, i can hear the beeps then plug back the red caliper on the esc, after that I unplug my receiver and batteries. When I turn power on, nothing happens... i didn't try to invert the motor wires order... do u think i have to try this? it seems to not be a solution...
I tried to modify EPA and trims, but without success...
Before asking this question I've readen many post about 9920, and didn't found anything that could help me.
I've tried to programm with and w/o the bec connector plugged, result is the same, motor does'nt want to run...

Do you think that it could come from my transmitter settings??? my EPA is at its maximum... I use a Graupner XS6-Race...

before trying this system I ran a HV-Maxx system, really more convenient to install, and to program... just a simple touch... after all i'm not satisfied of my new system, I would have better time to buy a new HVmaxx for that price...

Any help would be really appreciated!!!
All thanks,
Fagzz.

I want to precise that i use a rx pack during programming session... (but i programm with the black jumper plugged, if it isn't plug i don't arrive to programm the controler)
Do you think that i have to use the stock warrior BEC during programming?
I didn't try to programm the controler with the BEC enable (and w/o rx pack)... i will try tonight...
the problem does not come from my rx, because my servo works well...

I have had an case where the plug going in the rx would hit and not go in all the way. It would beep and could program it but it was hard to get to go or do anything. Try to plug it in the steering and see if you can get it to go. Yes the hv maxx is very easy. The power of you new system is more fun.

I had a similar problem because of a bad connection. Check your connections. The connection might make enough contact to make the beeps but not enough to carry current through it.

ok guys, thanks for your help.
I tried to plus the controler onto the steering channel, but nothing happened...
What connection is important? Do you think about motor connectors???

There all important. Mine was on the motor to esc though.

my controler and motor are absolutely new!!! if it's the cause of my problem. it's not serious! i will let u know,
tks for the help,
fagzz

that was not the solution... al my wires and connectors are absolutely well solded...
my controler comes from here, do you hink that I can send a PM to Mike to get more help? or perhaps someone here know what's happen withmy system?

check the battery bars....mike will definitely help you out if you can't figure our whats wrong

my batteries are good as possible...

the idea of Squeeforever is right imo, but i've not found any bad solder, or damaged connectors... my batteries are well, my receiver too... but it's a synthetized receiver... from Graupner... perhaps it's due to this rx??? i have to try with my old tq3 tx and rx.... i will let u know...

Is your receiver new? Try programming it without the steering servo, i had a bad one that caused my whole reciever to glitch and the motor would not run right as the servo took too much juice or something. I replaced the steering servo and it worked. Also, program without the bec plug in.

yes my rx and tx are pretty new... i will try to do what you say... programming w/o the steering servo...
tks,
fagzz.

I think Squee is right about your connections, but it also sounds like there is not enough juice so something can be taking it, do you run a shifting servo? If so, remove that as well. Synthasized receiver? Try stock rx and tx too.

yes i will try stock ones, and no i don't run the shifting servo, I use the Gmaxx 1 gear setup... i will try all those solutions tonight, and will let you know again...

I thought all my connections were good as well but turns out that they weren't. It didn't seem loose but a really good tug and it let loose. Soldered it up and it worked fine afterwards.

do you think that i have to re-sold all my wires??? sorry but i sold since 3 years now, and I should not do bad solders i think :) ok i will have a look...
But before I need to try with another rx, the stock one, and my stock rx...
perhaps it's just due to the rx/tx system... All the posts I found about this kind of problems were writen by people that had this kind of control system, specificaly XS6, and other JR radio systems... I found a few posts about my problem, but no solution to solve it... never... :(

i also run the JR radio, works fine now....

arghhhhh!!! i will become completly mad!!!!! 280$ for a so bad solution!!!
I will sell back my motor and controler, to buy a good HV Maxx...i think...

I wouldn't do that. I had an HVMaxx, yes it's easy, yes it fits nice, but patience with the new system made me more happy!! I love my 9920 and 10XL. There has got to be a bad connection somehwere dude. What are your batt packs like? Are they stick packs by any chance?
After reading back, there seems to me like it may be your receiver? what reciever are you running...are you running a shifter servo?

no shifter servo, i run the g maxx one gear setup...
rx is the one that came with my xs6 race radio transmitter, from graupner...

Is the red jumper plugged in all the way and making a good connection? Have your tried tuning down your steering trim? I would PM Mike and see what he says, he can also look at it for you. Has your shrink wrap on the bottom ok? you don't have it shorting out on anything do you? It would be well worth to find the problem

Are you sure the plug going in the rx is all the way in. I had this problem with the bk esc. It goes in and hits but the plug has little edges that catch and hold it from making good contact.

i shortened the battery wires of the controler, because the instructions say that i have to be careful about the wire length... less than 10cm between controler and batteries...
I have all the material to replace these wires, do you think that it could be the cause of this pb?

for the rx plug, it seems to be well plugged... and moving in the rx it doesn't resolve the problem...


please let me more time to try all the solutions that you provided before... i will take some days to work at this, all thanks for ur help guys! I've some axles for my researches... :018:

okay guys, i've discovered sthg... in fact i can program and run perfectly with the BEC enable, that mean that I can't use my rx pack... I never tried to do this because specs said that i had to use a rx pack with 2x7cells...
It was a little satisfaction... but now i would like to run my sterring servo in 6V!!!
After that I tried to plug the black jumper on the controler, and in this config I can run my servo at 6V!!!
But please can you confirm that there no risk to run the rx pack, plus the black jumper plugged onto the controler??? if it's ok for you all i will try to run these settings...

ps: i tried to do the programming procedure with my stock tq3 rx and tx, it doesn't work at all...

That's weird. To enable the bec, i think you need to plug the black jumper in? So it works with this? If you have the bec (black jumper in) enabled, you should not run an rx pack. Or, try to plug the black jumper in, cut the red wire going to your rx, make sure when you do this that the red wire does not touch anything.

i tried to unplug the black jumper with red wire plugged and rx pack also plugged ... it doesn't work until I plug back the black jumper...
But I don't want to let the red wire plugged on my rx, too dangerous...

Try this....with the black jumper in....pull the red wire out of the center of the plug that goes to the receiver...( it controls the bec)...tape it back to teh rest of the wire...make sure it is covered good, now try to run the rec. pack....

yes let me the time, i will sleep some hours and try before going to work...
i think that's a good way to force the controller... tks! :)

SJCRSS, I tried to do it, it works until i unplug the black jumper... after that it doesn't work anymore... what is strange is that i have my servo at 6V with the rx pack + black jumper plugged ang red wire unplugged... i don't want to kill my controler, therefore i wait for an answer from BKelectronics...
The only possibility that i have today is to run w/o the bec enabled (red wire cut), but with a rx pack and black jumper plugged... It's the only setting that work...

Hello,
I just have received an e-mail from BKelectronics, they say that I can run a rx pack with black jumper plugged, without problem up to 12cells. It doesn't help me, I only have 7cells packs!!! :(

By removing the red wire from the plug, you are disabling the BEC, so there is no need to remove the black jumper. that's how I've ran all my controllers,
Micro 1895 (had it for 4 1/2 years) BK replaced it with a Micro 2095...I've ran them in this config several years and have never had a problem, ranging from 12 cells up to 16 cells. So if it works with the jumper in but with the wire removed your fine.

WEll if you have the red wire unplugged or cut the bec is not working.

SJCRSS, you seem to be right, it's really strange that the instructions say that we have to cut the red wire + unplug the black jumper!!! It's one or the other, but not the 2 at the same time... i'm agree with you.
I will submit your remark to BKelectronics and see... Your way is pretty logical, I think it's the way to go...


All thanks for your help all, I hope that it's my solution. If it's right, I will PM Mike to update the Warrior instructions, cause I'm not the only one to encounter these problems...

I've been in brushless way back when Modeltech was around, and back then you just pulled the red wire...and didn't even pull the black jumper. I've never heard of doing both, but I have heard of doing one or the other.....In my case ...because the MIcro's are programmable via a pc.....pulling the black jumper wasn't a option for me...so I made a short servo lead with the red wire missing...and then I plugged in my controller lead into it....that way all i had to do was unplug it and I could program my controller.....but still have the BEC disabled when I plugged it into my lead with the red wire missing. I hope this helps.

Sure you're helpful!!!! All thanks!!!!! that is my solution, unfortunately I'm a swiss, french-speaking guy, and i think that I didn't read the instructions correctly... my damned poor english... :(
Warrior really needs some instructions in french!!! :)

glad I was able to help...try dealing with the program for my Micro controller that's on my computer...it's in German...luckily I downloaded the manual for it and had it translated by my wife's grandmother who's from germany...it made decifering it easier....But I'm with you...they need to do the instruction in more than one language...other than just English......not everyone can speak it ..let alone type it.

yes i saw the prog. software!!! what an horrible thing!!! All german interface... :( i sent it immediately to my recycle bin... :)
But at the end I have to say that BKelectronics provides a very good support, they answer in a short time, and really help u to find what happens with your system!!! Thanks BK!!! And thanks RC-monster friends!!! ;)

yes....Bk's service has really improved from back in the day....it's alot better than it used to be....when i fried my 1895 micro....(somehow I sent 123 amps) thru it...I sent it to BK...they said it could be repaired for $150.00 ...but in the end they sent me a Brand new 2095 Micro in place of it for the same price....and it only took 13 days...from the time i shipped it to them till I received the new at my doorstep.....great service......plus Mike has great service also..

hem... Mike didn't answered there, and my product came from here... but Mike did a forum for this reason, he can't answer everybody! :)

This is the end of this topic, BK answered me after a looooong discussion...
I didn't have to cut the red wire!!! I just had to unplug the black jumper, the effect is the same, in fact you cut the red wire in unplugging the black jumper... But BK recommended me to not cut the red wire, but to prefer unplugging the jumper...
I will try this las solution, and let u know...
The instructions are not as easy for you my english colleagues, as for us, frenc-speaking guys...
I hope that these 2 possibilities (cut red wire/unplugged jumper) provide the same results... if not i will take a gun and explode my Warrior!!!!!!!
