CC BEC done
 

i bought the CC BEC for my hitec 7950th servo and set it to 7.2v with my castle link. im running 2x 2s 5000mah 40c thunder power lipos with the stock traxxas 4 channel 2.4ghz radio. i had the BEC installed at my LHS by the same guy that i have solder all my rc stuff. i know the connection to the batts are good cuz the bec gets hot. and i know im not over powering the bec cuz its rated to 9v. i have only ran the truck with that bec 4 times, about 5-10 minutes each time and it has worked great until now. all the sudden the truck stopped, wheels stuck turned, not responsive. i opened the rx box and had no light on the rx. so im guessing i gotta send it in and wait for a new one rather than just exchanging it at my LHS... but i only hear good things about CC customer service so it should be a hastle right, besides the hastle of my brand new bec going fart....

the servos working tells me the BEC is fine. your ESC or the connections to your ESC is the problem. Did the guy remove the red (+) lead of the PWM coming from the ESC ?

i didnt say the servo works, cuz it doesnt, the truck stopped with the wheels stuck turned. he soldered the BEC wired at the trx connectors.

Test the servo with a different RX and power source and see if it is working or not.

Did you or the lhs guy remove the red wire from the esc's rx lead/plug to disable the built-in BEC? Im assuming the CC BEC is plugged into the rx, so the servo draws its power from there right? I would check the rx, bec and servo seperately to make sure it is actually the CC BEC thats crapped out though, just to be certain. :smile:

Observation: you have 'rc technician' in your avatar, yet you rely on an lhs guy to do your soldering for you- I love irony... :lol:

leave it to Neil to catch the irony of it for sure LOL I would definately change the Rc technician part if i was YOu :na:

I hate soldering, and usually if I buy the parts from there they'll do it for free so why not. The red wire is pulled to eliminate the internal bec and when I reconnect it everything works just fine. I did some trouble shooting before I posted ( remember, RC technician ). Its the bec.

Its OK. Ill leave it. It doesn't say " professional solderer".

Mine does!! :smile: Sucks about the BEC. There wasn't any binding in the steering links was there?

Niiiice!!!!:lol:

Nope, no binding, the truck was running perfect.

First bec, now esc!!!
 

now my esc stopped working... MMM. i went to drive the truck, first time since removing the BEC and i got a good minute outta her before she just stopped. no responce from the esc, no power, no smoke:no:. switch checked out good, lipos are charged, power wires are good. i dont wanna take the esc apart cuz i dont wanna void the warranty. this is pretty ridiculous. i just wanna good run for once this season!! what should i try? if the BEC died one run, and the ESC the next its possible there is something bigger going on. what?:grrrrrr:

Must be those RC gremlins again... Sometimes if you ignore them they just go away. :smile:

i have killed 2 ccbec's with 2 different HS7955tg, I'm starting to think its Hs servos, just send it back to castle, they are cheep mail out and castle has a great warranty service


fyi i said great but not always the quickest lol

hate to say it, change the servo and try again, i forgot what brianG said causes it but i have been there

A less power hungry servo seems like the best solution, and check your endpoints just incase.

Man, this servo is sweet though. I guess I can try another one. My axial Crawler needs a new servo. It has the CC Sidewinder esc on it, think that might work out?

Servo =+1 vote.
 

1 MORE VOTE FOR THE SERVO.

QESTION? If as you stated in your avatar you are an R/C technician, then shouldn't you be telling us whats going on here, not asking? That's just like listing that you are a Microsoft certified tecnician and coming here to ask us how to fix your boss's PC operating system.:whistle: Irony is a funny thing isn't it?:lol:

What does it matter? I'm pretty good at tinkering with the thing. When I run outta ideas I post it. I am the kinda person that's not scared to ask questions. It doesn't say castle creations Mamba monster technician, it doesn't say RC electrical guru. It says RC technician for fun, its not my profession.

Angry?
 

Look don't get mad at me.:na: When you go to get your 1:1 car checked by the auto technician at a garage he does not come back to you and say it is an electrical problem so you have to go see the electrician. "R/C Technician" means you are the technician who knows everything about R/C. What everyone is trying to tell you is that if this is not the case you may want to re-phrase your avatar. R/C technician implies that you are the go to guy for anything R/C. There are alot of guys in here who know an aweful lot about R/C in general. Some are very good at ESC stuff, some are good at powertrain stuff, and some are very good at suspension setups, but none of them list their abilities in print as an R/C technician, because it implies an overall specialist for anything R/C related.

If you hang something on a wall that implies you are a technician of any kind you better be prepared to back it up, or take alot of heat for saying so.:whistle: Besides having a bunch of very intelligent guys here on RCM there are also alot of very whitty people in here as well.:yes: It's not personal. So slow your roll and check yourself.

Considering the Castle BEC is rated at 10 amps, and the typical wires used for RX/Servo connections don't even support that, I don't think it's overcurrent from the servo.

How bout RC lube tech?

I hope not cuz im sure I'm not the only one running the hitec 7950th. I'm gonna send them both back to Kansas tomorrow and keep the servo, maybe its just a coincidence. If it happens again then ill swap the servo, I've been wanting to try a Jr racing servo.

There, I'm a wanna be RC technician

Perfect..
 

Now thats something that we can all hang on our wall and not have to take any crap for it.

What is a technician...
 

Wikipedia says,

A technician is generally someone in a technological field who has a relatively practical understanding of the general theoretical principles of that field, e.g., as compared to an engineer in that field. They are generally much more versed in technique compared to the average layman, or even the professional in that field. A mid-level of understanding of theory, and a high-level of technique, is generally mastered by the technician in order to become expert in a specific tool domain. This may be part of a larger (production) process. Hence, an rc technician, while not as learned in soldering as a Soldermaster Extraordinaire or an electrical engineer, will generally know more than other noobs, including traxxas forum members, and will be able to operate most rc equipment. Technicians may be classified as either skilled workers or semi-skilled workers.
Technicians may be found working in a variety of fields, and they usually have a job title with the designation 'technician' following the particular category of work. Thus a 'stage technician' is a worker who provides technical support for putting on a play, while a 'medical technician' is an employee who provides technical support in the medical industry or to the medical profession.

IMO Rc Technician was acceptable, while Master of RC, RC Pro,All-Pro and RC Pro Master would not be considered viable options.

I welcome you all to follow in my footsteps and become a Soldermaster, too! :lol:

RC Pro Master... sounds like a new Hobby City brand! :mdr:
