They were out of the 9918 stickers at the time. I doubt the sticker is any more than a coincidence. Quite a few have gone out with the wrong stickers. Hopefully we can figure it out.

what about maddogs problems? Any ideas Mike?

It is hard to tell without actually seeing the setup. Sometimes, a little detail can elude even the most experienced user. I am working with Drew through e-mail to fix the issue and will post when it is resolved. I am confident we will determine the issue and resolve it.

Well Mike, here is what i saw on the 9918 with the 7018 sticker...

There are 2 sorts of capacitors. (4 in totall) 2 brown capacitors and two black capacitors.. the 7018 has got 2 and the 9918 has got 4 capacitors.

The two brown ones, that sit between the wires are tight in place, and the two blacks (higher positioned) are easy to move.

Interesting. Are the brown and black caps both 50volts?

I am not able to check right now, i remember the one i read said 50 V 220u, don't know if it was the black or the brown. i am at home within a few hours, i will post that info as soon as i get home. I can't imagine they used two different types.

Have you got a 'real' 9918? and can you measure it? (weight?)

All the 9918 controllers I have had look the same. I didn't pick up on the stickers until a customer pointed it out, so I doubt there will be any weight difference.

Hey MadDog

I had a similar problem you did, but mine worked afterwards.

I would drive the truck normally, then if I stopped I would have everything else except no throttle. I checked for heat, bind, tried the thottle, then it would work normal. This happened on 2 runs, maybe 2-3 times. My last run of the day, the truck stopped again, this time I was able to get it moving by increasing the throttle trim on my stock radio.

I think the problem was 1 of the following: Cold weather, I think it was between 20-30 degrees. Or my stock. Since then, I have switched to a JR radio and the weather has been a tad warmer, but all I know is that I don't have the problem anymore.

Since brushless is new, maybe we are now seeing some issues, not neccessarily problems, but things we are experiencing.

My signature tells my setup.

Thanks for this experience, Patch. This is a Schulze issue that I haven't thought of relating to the BK controllers, but it is worth a try. I know the Schulze controllers need the throttle to be at zero to arm.
MadDog - please give this a try. I know brushless electronics in general are very specific on radio settings for safety reasons (built in failsafe).

I have tried to reprogram the esc and even put it in a different channel. I am getting no response from it.

I dont even get any beeps from the controller when i try to reprogram the esc.

Have you tried to set your throttle trim and sub trim to zero and tried to program it?

Yes.

Mike,

My gearing right now is 16t/66t. Would you suggest I leave it the same when my replacement parts get here, or would you change it?

I only have the one pinion (5mm shaft) but I do have a 70t & 72t spur I could put on there.

I just redid all the connections (dean plugs, UBEC, and wiring) on the esc to make sure they are all soldered nice and clean (looks tons better now). I also tested it with a stock e-maxx receiver and controller but still nothing. I am still getting NO beeps from the controller and no movement from the motor.

I have tried everything i can think of and nothing. I just dont understand why it just shut off like it did.

MadDog,

I saw that it was suggested earlier that you try a separate rx pack, but I never did see if you tried it or not.

If you haven't tried that, would you please do so? I want your problems fixed too since the sypmtoms (aside from my heat) being the same. We both use the UBEC, and it could be the common denominator.

I do not have a receiver pack other thank the UBEC (i built the truck from the ground up and didnt buy a receiver pack).

The UBEC should not be the problem though since the steering and transmission servo work 100% fine.

I'd almost go buy one for you just so you could test. I wouldn't rule it out at this point. It shouldn't be that, but far stranger things have happened. My new motor/esc should be here tomorrow. Which means I'll have it going by this weekend. If I still have issues after a few days, I'll throw an rx pack on and let you know.

I don't think that would have anything at all to due with my heat issues, but who knows, I could have more than 1 problem.

Either way, I wish I could talk you into running to the store and busting out a few bucks for an rx pack to test with, they're really cheap...

Come to think of it my T-Maxx has one, i will give it a try and report back.

crjackson,

thhe stock gearing should work fine. It wouldn't hurt to put the 72 tooth spur on, but you won't even give the 30150 a workout with that motor even with taller gearing.

MadDog,
I will send you a receiver pack to satisfy my curiosity. The UBEC should not be the problem, but I would like to make sure it isn't a factor. I have no idea why it suddenly cut out, but that is usually an indication of a battery problem (resistance from poor solder joints has caused this on some of my Schulze controllers).

I hooked up my t-maxx battery box with brand new batteries, still natta from the esc or motor.

Okay, I'll stay with the 16/66 gearing then. I really did love the performance geared like that, I'm just paranoid about reliabiliy right now. This is my 3rd BL system in 1 month. HV MAXX still at NOVAK, 9918/9L shipped back today, 30150/9L shipping in tomorrow (I hope). It's been a rough month for me. ;-{

Okay, thanks for trying. At least we know for sure now...

Yeah, that is a pretty expensive month you have going! I once blew up three controllers in one night! Two due to carelessness and the other was a Schulze (you never know why these go sometimes). It was a bad night for sure! What happened with the Novak?

I wish i had the money to just buy another esc, but i dont. I spent all the money i had to build my maxx, im flat broke right now and all i want to do is drive it but i cant :'(

Mike, what do you think? Send it in?

Why don't you go ahead and send it back to me. I will see if I can figure it out myself first (plug it into the computer and try to program it there via cable - this provides some historical info as well). Ifg I can't figure out the problem, I will have to send it back to Germany.

Alright, whats the address?

How long do you think it will take?

Looks like we were both typing at the same time! I understand the money thing, too. Perhaps Something will click when I get it. What radio do you use again?

I tried a stock e-maxx remote and JR XS3

It worked correctly for 1 day. Then progerssivly got to the point it wouldn't even run. It's been in Novaks hands for about a week now. I'm waiting for CharlieS to tell me what the cause was. Just before it died, it started thermaling a lot too... That must be the common thing for BL that's dieing. It's the cancer for them I suppose. It didn't have any controller issues though, it was always luke warm to the touch.

The controller is what usually thermals (not the motor). If the motor had a damaged winding, it would cause the controller to be more likely to thermal. I am curious what the cause of death was. Did the performance slowly get worse until it kicked the bucket, or did it suddenly die or did it start to thermal more and more until it finally quit?

Ok im confused now, who are you talking to? lol

I called it thermaling because (according to Novak tech, the flashing led indicated thermaling) yet the esc was cool. My understanding is that the motor it's self is sensored for thermal readings and the system will shut down if the motor it's self is too hot, as well as when the esc is too hot. That could be incorrect info. but that's what I was told, so I just assumed the motor thermaled.

Performance slowly got worse until it kicked the bucket.

Hehehe, don't ya just hate days like that. Man I've had my share...:eek:

Here's another similarity. I use the JR XS3 Pro...

I use the same radio??!!

MadDog: the address is:
RC-Monster
109 Collabar Rd
Montgomery, NY 12549

I give up!

Mike, i will send tomorrow morning.

Attached is how its curently setup, do you want me to send it all or do you want me to disconnect the motor and UBEC?

If i get no response from you by tomorrow morning i will send esc, motor, and ubec.

You can send the whole thing just like that. I will disconnect or re-connect anything I need to.

Mike,

I just wanted to let you know the new parts arrived at my door about 15 min. ago.

I was looking at the 9L and I gotta tell you it shocked me. My old (1 week) 9L has a LOT of end play on the armature shaft (1/16" at least). This one has almost NO noticable end play.

I hope somehow the other controller failure is related to that. I'll get it all installed in a day or so and let you know the results.

Thanks for really quick service,

Charles
