If possible, I'll cruise by the Ko pit next tuesday and lower the drive frequency 1 more notch, hopefully get another 10 secs of runtime before my motor heats this up too much
no prob. i usually have my handheld programmer with me, so if robert's busy i can hook you up. robert brings in his laptop..so its easier to see the profile curve. btw, did u pick up your dbl diode? dont want you blowing up a speedo i found a "single" at home if you wanna borrow it until you get your double.

Sounds good Chris. I picked up my dbl diode, and soldered a single onto it as well. Propably gonna use double Novak capacitors as well.

Hi, i know the vfs 2000 has a fet servo lead (the blue wire) but does the vfs-1 have the same (i know how to connect it up if it dosen't have it but it would be easier if it did have the fet servo wire).

No FET lead on my VFS-1. Kinda odd, since KO is only guys using FET wire, and their latest ESC doesn't come with one.

One of my mates has got a vfs-1, he's had it i think for over 2months for definet, he got it from a team driver. No i don't think you can get it from the UK at the moment (i haven't seen it adverised in the UK) that's why if i've got enough xmas money i might get it with adaptor from USA.

With the multi-setting adapter, on the frequency curve, does a higher number equate to more punch, or less?

I have been using the profile on KO's website for modifeid motors on technical tracks and have been happy with it, but when I get the chance I want to play around a little more but I don't really understand how the curve works.

Is there anywhere else I should look for profiles?

Thanks,
Josh

higher number = more runtime and less punch.
lower number = more punch, more brush/comm wear, and less runtime.

Ko site is the best place to get profiles. or ask here.

in terms of the curve.. look at it this way. there are 32 stages. stage "16" is the half way point. when you drive around your track, study the track and remember where you let off on the throttle and how much. From there, adjust the profile accordingly.

example, at the end of the straight, there is a 180 deg turn. you'd probably let off half way. at this point you want more punch, you would then adjust stage "16" on the throttle profile to give you more punch.

so.....

1/4 off the throttle = stage 24
1/2 off = stage 16
3/4 off = stage 8

etc....

If I may add :

higher number = more heat to the esc
lower number = motor becomes hotter

Default VFS200 software

I have the pc interface cable of the VFS 200. Can it also be used with the VFS-1 or do I need to download different software first?

Thx
