The 3.0 firmware update for the 2S speedo should be available within a couple of days.
It will blow you away

Can you tell us what's different about 3.0?

Andreas please understand ROAR reviews and approves the esc AND software.

So any one using 3.0 in Non-timing mode would be deemed illegal.

Do you need to have the Orca USB cable to update the firmware, or can you use a normal USB cable with the newer USB programming box?

I think the VX works with 2,4,8,16,32 and 64k for frequency, so high frequency give more power... which battery are you using? could happen that the esc tried send more power for the motor but your battery didnt sent enough power.
For me, 32k as always been the best setting (for offroad) on the VTC.
It seems the lower number means more low rev punch (more agressive feeling) whereas 32k and 64k offer a very smooth low rev and a more agressive high rev.
A gain in "raw power" where you want it is what the Drive freq. feels to me.

On the VTC, too high drive freq led to not enough low rev torque, especially on 10.5 at 64k so 32k was prefered.
On 4wd with a VTC/6.5, I have a good setting for our Euro tracks at 32k (bumpy astroturf, very high grip with lots of jumps). When I race on large dirt tracks, I only need to set to 64k and I'm done, super smooth, very nice.

On the VX, torque is consistent toward the whole range so 64k gives a strange mix of torque and smoothness on the first half of the throttle.
At high rev, the increase power is not that noticeable to be a disadvantage, yet top speed is quite big enough.
Up to now 64k has been our first choice on the VX, maybe also because a simple VTC/VX swap means a lot more power available (others things being equal).

For 10.5 blinky it became very usefull, smooth low rev and maximum power at high rev but 32k might be a good option too.
For big boost 10.5, 64k might be a bit too much when turbo is engaged, need a lot of slope but totally manageable, my favorite for 2wd offroad setup.
For modified, it smooth out starting/landing. Once you try 64k with proper gearing and mod motors, it's hard to come back.


I ran Orca lipos (5200/45c saddles) and motors (RX2).

Can't wait to try the new firmware then !

On the VTC, each new firmware has been a bonus so should be awesome.

I've tried pretty much every ESC on the market, and the Orca is undoubtedly the smoothest. These guys are doing something right.

I noticed that ROAR have updated their list yet again with P/N 360 (only the blue VX), but according to the ORCA website, all three colors of VX ESC have totally different P/N's.

VX ESC Titanium = OES380VX
VX ESC Blue= OES360VB
VX ESC Orange= OESC390VO

ROAR need to have three different P/N's on their approved list.

The firmware is completely re-written.
It runs smoother, faster and colder. (believe it or not )
The setup system is updated and makes it easier to setup the speedo and to understand what the different settings do and what to implement for different motors.

Yes you would need to purchase an ORCA USB Cable, OUL3680E.
Or use a friends one who might have one.

We know, we are working on getting 3.0 legal also of course. Until then, you would of course need to use the 2.2 software if running the 2S speedo.

The 1s speedo is not legal yet and when it will become legal it will only be with the 3.0 since it only works with the 3.0 and will only be available with the 3.0 software

PWM is definitely a useful tool to get the specific feel one is searching for.

This is so far what me team drivers seems to be using.

Blinky - 4k

Boosted stock - 32k

Mod
- High grip tracks - 8k (if you can handle the initial response)
- Lower grip or bigger tracks - 32k

Offroad - 2k or 4k (with high turn motor)
- 4k or 8k (with lower turn motors)

Again, its is all in the preference of the driver and how the tracks look like.

To be honest we did yet test enough with 64k, will do that more now with 3.0 as we have more possibilities with the setup now. We did not do that before as we lost to much midrange tourqe but should be possible now

Havnt posted it yet but its coming up.

ORCA VX (2.2 software) won the German Nats 2012 in Blinky mode in style.
TQ and win.

The speed is of course the same as any other speedo as its Blinky mode, however the small possibilities to set up the feel and the brake (drag/initial) in a way making it easier for 7 minutes running in an highly competitive race tempo

Hey Andreas,

I already using the ORCA package (VRITRA VX and RX2 motors) in both my 1/10 buggies and the performance is really smooth.

Will the new 3.0 software improve the performance for off road use too or it is mainly focused for on road use?

It depends on what settings you are using.
If you are using Zero timing or Turbo timing, then the difference will not be very big.

If you are running with Timing and/or Turbo timing, then it will also improve the performance/drivability since you can setup the speedo in a more specific way.

Mojo,

working with other esc that works also with frequency "directly" changing this parameters is noticiable the power because delivery more power and frenquecy and of course more heat on motor.

so if understand what you explained using high frenquency only is noticiable on high rpm and using lower frequency on lower rpm, in my view when you change the frequency you must have to try others FDR to try compensate, working with this idea maybe you can try lower frequency and 5.0 of FDR and high frequency and 8.0 of FDR (just an example)

im not telling you that im right we just change idea

Some drivers you can change also how AMP can be delivery for the motor independent PWM, so depending of motor will "consume" quantity and the excess that delivery for the motors cause heat and not more power

im asking because i work with industrial automation and programming some drivers that work with this parameters, PWM, Curve, compensation many others parameters so i have some ideias and experiences with this drivers

I want to try a VX soon
