Thanks. This is good to know.

Just to keep it relevant to ROAR, what wind motors were used. And how big was the track.

Only the speed passion 13.5v3 is allowed and the track was a largeish outdoor 1:8th track

We are not governed by ROAR but we use the ROAR list for speedos

I only asked for comparison to the US. The general issue is with 17.5 on the smaller, tighter carpet tracks, in this case the boosted is much faster and cooler.
The 13.5 and the openness of the 1/8 track, I would Imagine, do not require the same constant accelerations form tight corners, that is where the Heat is built up and where Boosted really helps.

This is also the Exact same way ROAR techs speedos too using this wave pattern that was put on paper after the Tekin problem early on. It was brought forth by Reto at LRP so there was NO gray area to exploit...it either matches this or its not legal. Pretty simple and I think it is somewhere on the ROAR page but may have been taking down.

Your too late. There is already a speedo that has Blue tooth technology that you can change settins while you are driving on the track (or your crew can rather). Its already been outlawed in some countries.

I'm thinking about going back to just running 17.5 boosted though because in 21.5 blinky I can drive the entire track at WOT. I can get slightly faster lap times if I let off for a split second on 2 corners. It really is quite boring and just screws up my timing for the faster class, so I think I'll drop it. I can't imagine how painfully dull true 25.5 USVTA must be. It's good for some people to learn how to steer and drive the best lines, but it doesn't even require a precise setup. If you get the ride height close and the car tracking straight, you're pretty much good to go. I've had many people comment on how dialed my 21.5 blinky car looks, but I know the setup on it is garbage, it just doesn't matter very much when you're going that slow.

I've won several 21.5 blinky A-mains, but I feel no sense of accomplishment from it. I'm far more excited when I win a 17.5 super stock B-Main or simply make it to the A-main in that class.
setup & driver is setup & driver....slower cars that are equal...will have a faster driver and better setup somewhere along the line. Somebody cleaned the bearings, somebody didnt...simple...same holds true for faster cars...if your setup/driver is jacked, you are going to fall behimd to the better setup/driver...

FYI...VTA 25.5 isnt slow...its FREAKIN AWESOME!!!!!!

And I don't know about you but I know the lrp x12 is the best motor for boost and the duo3 or ballistic are both good for NB so choice is always good. now some of these guys jumped into TC 17.5 NB running competitive laps straight off the back. I have had 4 SPXs 3 black diamonds and 3 tekins in the last 3 year. they are still running a GTB from 4 years ago Non boosted and being in the game. We're talking club racing here. Now I run a lrp comp sphere 007 and it doesn't matter what speed control I use it's all about driver at this point. If I run boosted it's Tekin or nothing else. SSX, black diamond, GM, speed passion all suck to tekin in boosted class. Kudos to tekin for getting it right but still doesn't make sense. And for the people that say give it 2 years and boosted will be the only thing. Um it's been 2 or 3 years since it was ALL non-boosted and we are going back to non-boosted. I think boosted has had it's swing, and it fell off it.

we also gained several TC guys cause of the non boosted crap...its helped our club with entries all winter long, which keeps us and many like it open so we have a place to race and enjoy this hobby/sport....so if its a vote...Im on the NB side

It was a tongue in cheek comment.

We live in a world where techno-logic development has evolved everyday life.
I just find it humorous that laptops at the races are seen as taking it too far, or too complex. Perhaps for some, but then that's why we have a blinky class

I'm sorry for dissing usvta, guys. My 21.5 blinky car does have an extremely free moving drivetrain with a decent setup. It just has shocks that I should have rebuilt a month ago, a diff that is less than silky smooth and a few other setup deficiencies that would no doubt become very apparent at higher speeds, but at 21.5 blinky speed it just doesn't seem to matter enough. Car drives great, but it requires almost no throttle control. That is the part that bothers me. I just don't find it difficult enough to maintain a perfect line even with a an imperfect car. Maybe I need a different second class. Some guys really love that kind of racing and I shouldn't knock it, so for that I apologize.

Bluetooth ESC's for what, to adjust drag brake? Not much else to change in blinky.

Anyway, I doubt you'd reliably be able to change anything while the cars are moving, our transmitters already stomp all over other 2.4ghz devices. Ever noticed how WiFi is crappy at every track?

The problem is, we got the same influx when we went from BR to BL. Why you ask? Because anytime you change technologies like this, there's a learning curve. At first, everyone is in the same area, testing to find what works. What happens is that the fast guys figure it out, and when they do, the less dedicated racers who didn't bother to learn it, quit again. So we dumb it down again, and they come back. Then, as the fast guys figure out the new formula, the gap returns to where it was before, and bang!! The less dedicated go back to dirt. The dedicated will always be faster: Welcome to motorsport.

The problem is that the temporary gains made, are just that temporary. So it never actually helps overall.

We already have slower, technology limited classes available, i.e. VTA. Do the GP2 drivers expect the FIA to neuter F1 to make the GP2 level drivers competitive with Vettel and Hamilton? Hell no, they're expected to get faster to get there. Why should we slow EVERYTHING down when a lower tech, more strictly spec'd class already exists?

My above posted rant is really aimed at the lack of a consistent LONG-TERM rules base. I really believe that every single time things begin to level out in the On-Road community, the rules are changed.

It's just making Nitro look all the better. Now where can I buy the secret tire sauce they used at the 1/8th Worlds?

yeah the motors are worked hard on the longerstraights and the gearing is also hig to gain the speed back ,BUT my motor reached a max of 75 degrees C at the weekend , i do still use a MM dynamic motor cooler before the raceand a heatsink with fan during the race but even with them last year my motor was sometimes in the 90's even as high as 140 degrees C

0 timing for stock is the way forward I believe

Not sure if its real or a fake BS site. But the Oval guys have already flipped out about it. http://www.trackshrinker.com/
