Default 3-questions!!

Thanks in advance for help:

1. Help-where do I find a reference guide for what the steps are and what frequency they refer to. i.e 1=920hz, 2=....

2. Also-can someone please advise me on a good 19t set-up for a carpet/foam 95x50 ft track?

3. And last-what value for throttle response are you guys using for low turn (7x1 and 8x1) mod/carpet/foam?

THanks again,
Ray

Thanks,

I don't know if this question had been asked before, what's the difference between the VFS1 and VFS2??? I've been told that the VFS2 can also stand mod motors.

Thanks.

Hmm Iīm not sure if the VFS-2 should be used with hot motors. Itīs just a budget version of the VFS-1 with less FETīs.

[rayhuang]Thanks in advance for help:
1. Help-where do I find a reference guide for what the steps are and what frequency they refer to. i.e 1=920hz, 2=....
Attached below is a pdf attachment which shows you each frequency step.

2. Also-can someone please advise me on a good 19t set-up for a carpet/foam 95x50 ft track?
I currently run the setup below which I helped Goop with.
I would Recommend running this profile only if you have some good Gp3300 Packs with some runtime say 420. You can also adjust the Current limiter value which will give you more rip out of your motor(the higher the value the more current which is applied to the motor), the key thing to look at is the temp of the motor in addition to the brush life.

Current limiter: 160
Neutral brake: OFF
Throttle response: OFF
Power save voltage: 2.5 BEC
Frequency of brake: 32

5 <--- starting point for throttle curve

3. And last-what value for throttle response are you guys using for low turn (7x1 and 8x1) mod/carpet/foam?
There is Nine stages (off and 1-9) that can be set, One becoming the most Aggressive, and 9 becoming the mildest. Please test and look at the conditions of the track because the effect will differ. This may also be effective when combined with the throttle punch funtion of the transmitter when the track conditions are slippery and the motor is too aggressive.

As to what profile to run, I would Recommend running the Hara Worlds Profile for Touring car which can be found under the US Ko Propo Web Site http://www.kopropo.com/vfs_help.htm. Also I would recommend running the Ko Propo VFS-1 Pro Double Shotki Diode Part#KO45516 if you plan on running MOD.

I will also be attending the Sizzzzlllaaaaa, so If you still have questions or any concerns please dont hesitateto ask.

Best Regards

That diode pictured is not the double, that's the single. The double's thickness is a tad more than twice of the one pictured. Just to help out if someone had a question of the two ... -JB
