Feigao 7L, Warrior 9920 + 12 GP 3300 cells = hot?

[Dafni]

Glad you have it up and running, but the glitching you described sucks. I never had any glitching, just make sure everything is well insulated. Antenna and receiver. I'm sure you can work this out. Otherwise Mike, me and the boys here will help you to find the cause.

What are you running for BEC. A batt pack or a UBEC, or do you use the internal BEC of the controller?

How do you like the motor so far? Speed and acceleration?

I had the problem with a bec unit, receiver pack and the controller's bec. I went back to internal bec now since it's the simplest way.

Maybe I'll try to put in another servo to see what happens.

I haven't had time to test the car with the 9L yet, maybe I'll be able to test it in the track tomorrow.

[Dafni]

Hmm, sounds strange. I never heard of a servo producing a glitch.
I hope you can get this worked out. The motor ran well in my Twinforce.

[RC-Monster Mike]

For 12 cells, the internal BEC should be perfectly fine I have used mine up to 22.2 volt Lipos with no trouble!). Also, it is fairly common for a servo to cause a glitch, believe it or not.

[Dafni]

As in Servo glitches, or as in Servo makes ESC glitch, or both??

[RC-Monster Mike]

Both.

[Dafni]

OMG. Do you americans know the saying: Knock on wood. ?

Are there some common ways to deal with it besides getting a new servo or relocation the ESC?

The internal BEC seems to generate at least some heat. When I used the 7L with internal BEC the heatshrink melted where apparently the BEC is located but then the controller was overheating regularly anyway.
I hope that it runs cool enough with the 9L so I don't need a fan or external BEC...

[RC-Monster Mike]

Put a barrier between the servo and the controller, such as a couple layers of mounting tape, and keep the antenna shielded as well (fuel tubing between receiver and the antenna holder for example).

I don't know if anyone has noticed this, but I have found the Warrior to be a "noisy" controller. As in it produces quite a bit of interference. With my 9918, I can only get about 150ft of range with a 75mhz FM radio. When I had my MGM (it's being serviced), I could easily get 300ft, which at that point I couldn't see the car very well anymore. And this is when using an external BEC with the 9918 and the MGM's internal BEC.

[Dafni]

You might be right, Metalman, but I never had problems on mine. (I never try 300ft on my AM stuff, LOL)

Strange thing in Felix' case: It worked fine on the other motor...?!

No it's happening with both motors now.
Just worked before I resoldered the plugs on the controller.

Are you using a PLL transmitter/reciever?

I too had this problem, that the esc caused noize, resulting in a shaking steeringservo and a not 100% topspeed of my Schulze.

All of these problems were gone when i changed my PLL to a Multiplex 301 RC..

I just read my reply about you asking for the price on the 9L or 10L, i understand, you're talking about the wanderer and not the feigao..

I have a Wanderer 7L and a Feigao 9L now.
I'm using a Graupner/Futaba XS-6, I think it's FM.

[Serum]

Okay.. What can cause interference is an antenna touching CF or metall..

That XS-6, it can be a synthesizer, does it use x-talls, or can you adjust the frequency by hand? keep the receiver as far as possible away from servo's and the speedo.. weird that it did worked well before though..
