Yeah that is kind of the point in winning. They knew what they were doing and weren't upset about it melting down. I'm just pointing out that despite all these new timing things the fast guys are still pushing the limits on temp.

you start rpm is way to low. my 17.5 is at 3500 and my 13.5 is at 4000-4500. the end is ok for a stock motor, but the end for 13.5 is way too low. if this is 13.5 this would be like my setup on the tekin site foe 17.5 it has all the rip in the world out of a corner. but it 13.5 i am not sure many of us could keep hold of a car with that setup.

1. lower your throttle profile.
2. increase start rpm
3. if 13.5 increase end rpm.

the wider you have the rpm range the smoother the power comes on. 17.5 is probably the only class you want the car to shoot out of corners that hard.

Will you guys be there this Sunday or are you only going to A-main on Saturday?

Saturday I tried an other setup but the motor became above the 180F.
I changed gearing and my gearing. My motor temps went down but not my lap times. Whit the setup that I have now I'm a bit faster in the infield and a bit higher top speed.
I lowered the top speed so I could go true the corner full speed like the others. With the higher top speed I had to brake and lost all the advantage.
I played with the start RPM settings to get a better acceleration and that worked. My car accelerates now very smooth. It's also good to drive.
I had a faster setup but it was in the infield to fast and top speed to high.
I drive 10,5 2 cell lipo and the track is small and technical. So to much power will make it harder to drive.

keep learning

One great hing about this ESC and software updates is that it keeps people learning and something is constantly new which makes anything more fun. After reading this thread daily I have just a very basic general summary:

this is comapring 13.5 and 17.5 motors in TC:

13.5 motors should have a higher FDR (i.e. 7.0), a higher start RPM, and a wider RPM range

17.5 should have a lower FDR (5.5-6.0), a lower start RPM, and a narrower RPM range

Are these basic statements correct? Thoughts please.

Any idea if they were using fans on their motors?

I've found even a cheap 25mm fan wired into the ESC will drop the temps by 30F. I imagine a high RPM fan to the battery could really move some air.

Actually they were not running fans. I have found the same thing. Just a fan can keep the temps down 25-30 degrees. I had been hooking mine up direct to the battery but I got a new Muchmore Ultra high RPM fan that I just plug in the receiver and it seems to do the job just fine. Definitely not as cool as direct but I think some races (like ROAR) don't allow it direct to the battery.

Not sure how much the fans would have helped these guys though. The guy that TQed and won his motor was 230* when it melted down.

I've been running the Ballistic motor and it really falls off at 155 degrees. The fan is a necessity with that motor.

In the Netherlands www.hanglooseracingproducts.nl is selling them and in the UK it's much more as I'm right.
More I don't now.

I'd believe it. They just seem to come to a crawl at 155*s for me. I was talking to Brandon Shells about it and he said he found the same thing. I have had mine up to 172 degrees when my fan stopped working. It seems to still work fine but I was concerned. Kind of makes me want to go back to a Duo because those seem to be fine until a little over 200*.
