Never did...that's why Tekin had to come out with the RS...the R1 just couldn't run 17.5 motors without cogging.

i would think for most racers it will not make a difference. and maybe for top racers worth 2/10s per lap at best on a 13 sec lap on 13.5T brushless?

maybe more time can be gained by tuning the car rather than worrying about escs that provide marginal advance (if you are a good enough driver to take advantage of it)

just my personal opinion, these new escs make no difference to the average club racers like myself. it will not make me faster.

thoughts?
It really depends on the track. Smaller carpet tracks there may be little to no difference. Timing boost really makes a difference on bigger tracks.

Absolutely. Our track is one where of those where the difference is impossible to tell.

Should boost/turbo be legal for racing? Absolutely not. Racing, no matter what form, is supposed to boil down to one variable........the person.


Would the winner of a Nascar/F1/Supercross race still retain the title if they were found to have a timing advance system on their car?

Depends if its in the rules or not. In the case of RC there is nothing in the rules preventing it.

There is definitely an advantage when using the boost function on the Tekin. The difference in lap times is significant even when adjusting amount of boost relative to amount of turbo. I dialed my boost down and turbo to max and dropped a second off of my lap times. (@16-17 second laps) This is a great tuning option to have and varies depending on track size.

If I can gain 2-3 tenths per lap by tuning my car AND 2-3 tenths by tuning my esc, WHY NOT? There's no reason to choose between the two. I gained 3 tenths per lap today by switching tires.

As far as making them illegal. No one wanted to make the LRP illegal when it was outrunning the Tekin. Now Tekin has caught up and it should be outlawed?? The only speed control that should be illegal is the new Advanced Electronics speedo. NOT because it's fast, but because of the price.

Nascar probably not
F1 yes...so long as they still stayed under the HP and RPM limits in the current rules
Supercross...not sure

At any rate all these organizations have huge resources to use for technical inspection and take a great deal of time to perform them. Neither of which can be done in RC as most races barely survive financially and no one is going to let a tech official hold on to a car for a day or more to properly do a tech inspection. Not to mention even if they did make it illegal it is quite simple to get around a tech inspection by having the ESC default back to a legal profile as soon as you turn off the ESC.

Hasn't F1 already gone to driver adjustable wing positions as well as onboard fuel mapping? The drivers can adjust their cars for different sections of the track as they go.

All those vehicles you mentioned have ignition timing advance, just sayin

Street cars and motorcycles have ignition advance on them, diesels use fuel injection timing advance.
Lawnmowers and Subaru's don't

No...moveable aerodynamics is still banned in F1. They do have different engine mappings though to save fuel or not. Typically it isn't used per section of the track but for when they need to conserve or not.

Thanks. I'll go back to my corner now.

Let the technology develop on its own. Making rules that restrict the evolution of better technology won't do anything to help the hobby. The racetrack is where the vast majority of R&D goes on. Without racing, there is no incentive to generate better products. All you get then is more bling for bashers.

Let the 17.5 class be. As a few have said, racing is about the person. Well that does go for driving but don't forget that successful racers are also those who can dial in the perfect setup every time. The esc is just another dimension of tuning. If someone can figure out what the perfect settings for a certain type of layout are, more power to them .

On the issue of 17.5/13.5/Mod... They are really all considered an "expert" class. To go fast they all require a significant investment in equipment and a steep learning curve of setup skill. Adding a Sportsman class could be set up by requiring the "default profile." Speedo makers could install an led of a different color that lights up when the default profile is selected. Teching is easy, just park it after the race at the directors table and he can visually see the colored led without any invasive tech proceedures.
