Might be a dumb question but...what is the VFS-1?

I am an importer of the Rapidas. Oviously I have no experience with the VFS-1 but if its from a well know company i'm sure its an excellent speed control that any racer would be happy with.

All I can say about the Rapida is that I have used Keyence stuff for 4 years with good results. Lots of guys here will say the same. The main thing Keyence can offer you is a phone number and an email that will get you answers from guys that actually have Zero V Ex's or Rapida Pro's in thier personal cars.

Novak and LRP and KO can also provide this type of service.

I know that the vfs-1 come either with teh esc only or the hand held controller. What happens if I don't get the controller - how do you adjust the setting? Is the default setting good already?

I'm kinda of leaning towards Ko because i have a helios and it would be nice to have all the electronics from one company! Hehe..

The default setting is good enough.. but if want to use the speedo to it's full potential get the handheld controller... it will be cheaper getting it as a set then buying it seperately later.

either speedo you choose will be a good choice.. they're both excellent.

hey loosenut

you might have to flip a coin. like the previous posts say.. both escs are high end competition level escs.

if you opt for the VFS-1, get the combo package so that you can adjust the esc. the default setting is "okay" for stock. and pretty good for mod. with the programmer, you can program it (see the VFS-1 thread for programming help and profile advice) and really take advantage of what the esc is capable. its definitely an advantage for stock, 19T and mod when you can dial in more punch without having to adjust your final drive ratio.

one thing tho.. the VFS-1 doesnt say "hello" to you like the Keyence does.

Ultimate hobbies,
Do a phone order they offer free shipping and good prices, there the west coast importer of Keyence
714-921-0424

rapida's are 169.95 last i checked
I think they might even come in 2 colors black and blue, they also carry the rest of the Keyence line.

I also have a Helios, and my rapida works awsome with it.

ohh and yes there in stock, I just saw some in the showcase today =)

with the rapida you don't need a external devise to change the profiles of the speed control like you do for the vsf-1 or the older cyclone series from novak which are still awsome esc (got two when they came out 3-4 years ago not a moments trouble) it's nice not to have to carry somthing extra around to adjust your esc
my zero v-extreme is just about the best controler around tells you batt. voltage heat of the esc can hold several different profile for different track and/or track conditions.

I have the Keyence Rapida pro in my 12th scale and it's by far the best speed control I've ever owned. Lots of settings, easy to set (use your radio to scroll trough the settings) very reliable. I've had no experience with the Ko speed control, but I would give the nod to Keyence any day.

Keyence is the Lexus of speedos. Once You have one, You'll not want any other.

To be serious:
I have both speedos, and the KO ones (twister, mms3, volac, etc.) are the best of the rest.
The difference depends on the type of motor you use. The more power you drive, the more the difference will be.
In case of 17T and 19T motors, I'd say that there is almost no difference. I run 12T modifieds, and in this class, the Keyence is significantly better:
- more punch
- lower motor temperature
- Longer commutator cycle and motor life. Truing the comm after 4 runs means .01-.02 mm diameter loss only with Keyence, .02-.03 with Ko and .07-.1 with LRP/Nosram QC2.
- Longer runtime - Keyence: around 8 minutes with 0% Ensa, 4400Hz drive, Corally Black 12*1 Grooved HT timed 24 degrees (max RPM 51000 at 21 degrees on tester). Ko: around 6-6.5 mins (tried only 21 degrees timing). LRP/Nosram: barely 5 mins with 21 degrees timing.
