My opinion is that you should run VTA rules as closely as possible. We run "Outlaw" with 21.5 motors in So Cal because so many of the UF1 group also wanted to run VTA with the 21.5 they already have. It was a reasonable compromise made to build the class while keeping close to the intended spirit of VTA.

I would tend to agree, but if its not an old classic car or a new mustang or camaro, most of these guys dont want to drive it. Some of them want to run single digit wind motors. Go fast or go home menatlity.

We had guys complain about having to buy a Novak motor for VTA so our track allows 21.5 motors but we run a breakout rule so no one goes too fast. Most of the time it is the guys running full USVTA spec cars that are winning our races though.

I hear ya...but there is nothing to prevent those guys from running any era Pony/Muscle car body in USGT. In fact there is nothing to prevent those guys from running HPI Vintage tires in USGT (depending on local track rules). I've seen a few local racers who race USVTA & USGT use VTA fronts on their USGT car - and have good results.

----------

At the end of the day, each track/group of racers need to do what it best for them. But if at all possible, run USVTA rules - it will make the racing good for just about every possible skill level.

Nope, turns it into a Havok and it is no longer legal for USVTA. Now my dirt oval car...

how so?? based on what I've been told (talked with Charlie @ novak), it adds adjustability to the speedo, not changes the speedo

I'm curious what you've found

That's awesome seeing VTA like this abroad! Great looking track, too.

Thats the way I feel about it. The USVTA rules serve as a light house so that everyone can stay compatible on a national or international scale. Robk does not have the time to go be the Nazi. Its enough just to be responsible for the template that everyone looks to, should they choose to use it. Eventually the track or club has to decide whats best for them. The way I see it VTA with 21.5 is a gen2 rules car. Some clubs never switched to the current rule set and they are still running them like that. If a car like that shows up at a track running current rules, One they should know that they are not compliant, but Two, Thats still a perfectly acceptable ride in USGT. So if that driver does not want to carry a VTA legal motor and speedo, which would be easy enough, then their best option is to run the car in USGT.

The added adjustibility is what makes it illegal. The main difference between the Havok Pro SC XD and the GTB2 X-drive ESC is the brain board. The upgraded board and the Havok board both allow you to add boost and set dynamic timing (take it out of blinky mode as it were). The timing on the GTB2 is not adjustable. The promo for the board says:

PRODUCT HIGHLIGHTS

Includes Super-Tuner Firmware for quick and complete custom tuning:
Drive Tuning: Dynamic Timing Advance (0-55°), RPM (Start/Final/Range), Drive Frequency, Minimum Drive
Brake Tuning: Brake Frequency, Drag Brake, and Minimum Brake
Additional Tuning: Dead Band, Reverse Disable, and LiPo Protection (On/Off)
5 Profiles that can be independently customized and saved for multiple set-ups and easy trackside changes
Extreme-duty 5A BEC to handle the demands of today’s high powered servos
6 specialized RPM tables of Start & Final RPMs for fine-tuning the Dynamic Timing Advance™
Includes non-timing, blinking white LED to meet ROAR Sportsman Class racing standards
Compatible with Havoc Pro SC (#1745) that has X-Drive™ firmware, and GTB 2 X-Drive ESCs (#1748/#1749)

You will also notice that it comes in a new case labeled "Havok Pro SC"

Includes: Brain board with Super-Tuner firmware, Havoc Pro SC case and screws, installation instructions, programming instructions, and flowchart sticker

The Mos-Fet/heatsink board appears to be the same for both the Havok Pro SC XD and the GTB2 X-Drive. The difference is the programming and components on the "Brain Board". When installing the Havok Pro SC Super Tuner upgrade brain board in a GTB2 w/X-Drive, it turns the GTB2 X-Drive into an upgraded Havok Pro SC which is not USVTA legal.

However, I am thinking about getting one for my Havoc Pro SC SC in my loose dirt modified late model. The upgraded 5 amp BEC will help with my 6.5 Ballistic motor and lots of cooling fans.

HTH

P.S. I really need to read all the new thread posts before answering

So you have the same vision problem(s) I have

thanks though

I was more or less looking at the update board for 17.5 - ie, removing my x-drive speedo from the USVTA (and going to either the hobbywing or my non x-drive gtb2)

sounds like this update makes the speedo a little more competitive in the world on blinky-mode speedos (vs locked blinky-only speedos)

yes, I know blinky is blinky is blinky - but there are feel differences in speedos

anywho...thanks and not back to USVTA discussions

I still hold to the idea that if Tekin or anyone made a super small esc that somehow blocked out timing and boost while still allowing for a hotwire style interface for the other features, that would be the bomb.
