Default Condenser and Diode Location

KO Staff: (or anyone else that can help).
I've got a similar question to rattlr2.

First regarding Condenser, does it have to be soldered directly to the (-/+) battery leads on the ESC? I wanted to add two small leads to relocate it so I could strap it down somewhere else on the chassis. If I'm using deans connectors, could my Condensor leads be soldered into there the ESC leads are soldered to the male deans plug? (Hope that makes sense).

Second, regarding the starndard KO diode that comes with the VFS2000, does it have to be soldered directly onto the motor? I wanted to create a harness, much like the diode harness for the GT7, where the diode is soldered inline, in route to the motor leads. I would also solder in the lead to connect to the (+) battery terminal.

Any idea if this works or how it affects performance?

Thanks for any input.

The idea is that the closer the diode is to the motor, the better it will help to prevent noise and help efficiency. I have tried it inline on the motor wires and have had no problems. It is just our suggestion to prevent noise and help to reduce the short that travels to the ESC when braking.

For your first question, that would work.

Your second, see the previous post.

Okey dokey ! thanks Robert. I'm just confused seeking clarification. You've been most helpful.

The postive pin on the lead going to the receiver must be pulled. Don't cut it, because you will need to re-insert it for setting changes.

Yes you will need to trun on both. The receiver pack will only power the receiver and servo and the VFS will only power the motor. Turn on the receiver pack first.

Default too many schottkys?

Is there such a thing as too many schottkys for the VFS 200J?

On my monster stock powered CGM I am running a KO hyper booster, the schottky included with the VFS 2000J and a Novak schottky module. Is this over kill? At the moment I am finding a lack of bottom end after braking for a hair pin corner. I am also running the standard cap and profile of 17's.

jiggen.. if your lacking punch. try adjusting your profile. you said its at all 17s right now...

try dropping the first 16 stages to 10...and on the 17th stage start going up. by stage 32..end up around 17-22/23... depending on how the top end feels, comm wear and run time remaining, adjust accordingly.

dropping down to 10 will give you a lot of punch for stock and 19T, but more wear on your comm.

KO PROPO staff,

I have a problem with my VFS 2000,
1 month ago during a race the speedo didn't want to work at all, only the red LED were on but absolutely no signal to the motor (steering servo was working fine).
After a few days I reinstalled it in my car and it worked like before.
2 weeks ago I attended a race and it did exactly the same.
It seems that is not possible to download any program since the ESC is not "reacting" when I push the setting button and when I plug in the battery the ESC is turned on already (can't turn it off)

I don't think I can fix this myself.
Should I send it to KO USA or KO J-Land?
Do you have any contact/address or e-mail if it is in Japan
Will it cost something?

Thank you very much.
Best regards.

Gilles

hi guys, need your feedback:

if i wire my VFS2000 to the GT7 wire & schottky diode harness kit, would it be sufficient to run a 10-turn modified motor? or do i still need to solder on the original KO super schottky diode?

also, do i need to install another additional power-up condensor?

thanks.
