Okay... I have no idea what this is... Am I dumb?

[Cheetah928]

Hey there! Opened up my new xl-5hv to make sure it fit the new motor and found a piece in the package and I have a total of 0 clue what it is and what it does. I've seen them before, but never had to install one.

Pardon my finger in the photo. That gives you a reference as to the size of it though.

Don't eat it. It's a ceramic capacitor, solder in type.

Don't eat it....... I love it! Brings back partial memories of working in a pharmacy.

An hour or two in id look at thr boss and tell him I can't feel my face.

For use across the (+) (-) terminals of a brush motor. Reduces electrical noise from the motor that may cause glitching in a brush ESC or radio interference on old school AM or FM radio systems. -AC

That's because you're hands are on the boss' face.

I'm pretty sure it's .05 uf or 50pf, not that it matters in this case, I was just proud of myself for remembering.

Turn it around. Is there a smiley face on the back? You might have WON!!!

My last free gift from Asia was a tiny packet of tissues from Plazahobbies.com I'm not sure if I'm missing stuff or what here but hmmmmm...
Weird RC free gift, right?
( they actually did fantastic with my order, again!)

AC is correct. Noise cap.

So do I need it? I'm using a rc 4wd 27t 540 brushed motor. Should I use it?

 

[CertifiedMike]

I don't know if thry matter or not with new radio systems. They sure helped with the old ones tho.

I wanna build a street car from the ground and put a crystal radio in... I love the classic charm!

And thanks!

 

[ahr43]

+1 on what CertifiedMike says. Try running a glitch buster off a port on the receiver first. Just for insurance against glitches. Less hassle than soldering. If you do get glitching, then solder in the cap. -AC

Then yeah, use it

Thats cool! I'd love to hear how your experience with the old radio goes. I have a few oldies myself. I hate seeimg them sit in a box. I have cars that could use radios right now.
I'm terrifed to run anything thats real fast tho.
Even my Futaba radios got glitchy aometimes.

 

[Cheetah928]

Then yeah, use it

But this one is for my trx-4. Haven't thought out the car

Not sure why you'd want to run antique radio gear on a modern kit. Is it just because you have it already?

I have old FM radio gear, but I would never give up my 2.4ghz stuff for nostalgic purposes. It's just so outdated, and problematic, that I can imagine with all the new signals flying through the air these days that will only make the stuff worse than it was 20 years ago.

Yeah, i don't miss old radios
Just wanted to mention that the "glitch buster" (just an electrolytic cap worth a couple of cents) stabilises voltage - basically provides an extra reserve of charge when your BEC is overloaded by the servo. Modern ESCs shouldn't need one, and if you get brown outs, install an external BEC.
The ceramic cap that you find on brushed motors (or included in the box) served to suppress electromagnetic fields generated by brushes arcing that can interfere with old radios and electronics. Nowadays the're pretty much unneeded too.

The marking "503" on a ceramic capacitor uses the EIA three-digit code, where:

• The first two digits are (50)
• The third digit (3) is the multiplier (10³ = 1,000)

So:​

503 = 50 × 1,000 = 50,000 pF, which equals:

• 50 nF (nanofarads), or
• 0.05 µF (microfarads)
