I just watched the video with the 2nd Amain in which Masami lost to the young Yokomo driver.

It really sucked to watch the drivers run out of power on the last lap..

Four cells: definite one-run batteries for top racers at top races, careful battery management needed for runtime, no longer a matter of just going to the shop to get the best batteries off the shelf as with six cells.
What happened to motor limits? Why restrict batteries, just restrict the motors.

The reason the batteries are losing runtime is because they are being dumped on the track. If you dump these cells excessively at the end of the run you will kill the pack. We tell all our drivers to pull it off when it starts to dump. Of course, if you are in a race you need to do whatever it takes to finish. However, in practice, when the pack really flattens out, pull it off. This is not exclusive to 4 cells. It also happens with 6 cells, too.

If you don't dump the pack hard on the track you can definately run the pack many runs. It has nothing to do with the packs being 4 cells. It all about not dumping the packs hard on the track. The key to keep this from happening is car setup and motor setup.
The same thing can happen in 6 cells but hasn't yet happened as the motors have not been able to be tweaked enough to make the packs dump. Last I heard motor builder/tuners have been able to use up more battery power so dumping can become an issue.
I personally think 4 cell is a step forward. After all 4 cell 12th scale has been around for a long time and they could easily dump each run but the fast guys are making sure to manage there packs by using a bit less horsepower or simply not driving as hard.
As with anything new we need to give it sometime.

A pack should last a season, minimum, no matter what. If motor turn reduction, current limiters, whatever, are required, then so be it.

To me it sounds like the guys in Japan are having fewer problems.

the solution to the whole mess could be controlled by three variables:
-race length
-tires
-cost ceilings
regarding the race itself, i'm happy to see masami still wheeling it to the top. go old guys!

John,
are you able to find the 1st and 3rd main's video?

So:
over a month straight of testing
perfectly molded, impossible to find tires (used for one run)
one-run batteries (well at least they weren't one-run motors)
track layout hasn't changed in 10 years
You could guess that world champs from previous visits to Yatabe would be in the top 3, eh?
I don't see why non-Japanese drivers even go to the Nats, it's just a waste of money. The JMRCA AGM is supposed to be coming up, hopefuly they change things to spec tires and figure out what they're doing for batteries. I don't see how the Japanese RC market can welcome new drivers to the hobby when these types of stories dominate the biggest races in the country. It's only supposed to be LIKE Formula 1, not ACTUALLY Formula 1.

He is the tire master. He spends more time obsessing on tires than anyone. In South Africa he had at least 1 car hauler bag full of metal tins containing various traction compounds. I am sure he has tested them all at one time or another.
No one comes to an event more massively prepared than Masami.

Well, winning so many and important races, doesn't come easy or cheap
At the video of the 2nd Amain, he could easily hold the young boy and take the win of the main and of the overall event BUT he pulled away!!!
This is something you don't see very often, especially on such events!!
