Post Straight V8 Capacitor

just received one of those cool capacitor boards made by Straight, it came with a resistor and a usage guide... japanese only

so can someone tell me if i need to solder the resistor between ESC and capacitor or can i leave it out?

tia,

Oliver

Hey, I am using a Straigh cap v4 (the big ones)... i got the small caps too, the shop owner that sold it to me told me to put it parallel to your diode (across the + and - terminal) over the motor. I am not sure exactly what it does though.

Hope that helps

that's the way you should solder it

Ok, I see the photo now, but where is the resistor in this picture?

It's a capacitor not a resistor. You solder capacitors inline with the battery on the ESC posts.

hmm.... very true... its a V8 Capacitor but it COMES WITH A RESISTOR...

and it is that resistor, that omoser and I are having troubles figuring out where to put... and the picture posted by benoitrdv does not show

Where can you get one of those capacitors?

so... my sister translated parts of the manual, even some things sound funny, i think that the resistor belongs across + and - between ESC and capacitor board... this way, the capacitors get discharged by the resistor if there is charged left in there (that's at least what she was able to translate )... seems to make sense.

Anyway, I think one can also leave it out at all, didn't find any picture where the resistor is used with the V8. Even Straight's website do not show it: http://www.cna.ne.jp/~straight/Products/rok9/rok9.html

anyway, I'll leave it out for now. I sent an email to [email protected] asking for help, maybe i get an answer

Does anyone know what the 2 types of capacitor are rated at?
How many uF??...

Also - working voltage?

I translated their site using Google but no specs!!

Dear Mr.Moser

Thank you for purchase our product.
You do not need solder the resister any where.
The resister is for avoid damages when put V8 on and off the RC car.
Direction is as following;
Disconnect the RC baterry
Short two terminal of V8 by the resister

Please do not short terminals of V8 directly.
It gives big damage to the capacitor. OK

Straight Ltd.

Still cant figure out what the tiny diode does with the manufacturer's reply.

Does it mean that before you add or remove the capacitor to the ESC, solder the diode across the +ve & -ve terminal?? After that, just remove the diode again??

Can someone pls enlighten?

you don't need to solder it, just shorten the terminals of the capacitor with the resistor to get out any charge left in the caps. Here are the emails i got from Straight LTD.:

Dear Mr.Moser

I am pleased you understood perfectly.
You are right.
I hope you feel V8 performance.
We are tying to expand business in Euro this year.
So you will be able to see our products in a shop near you.

Thank you again.
