Just some info that was given to me from Team T


The goal is to keep the motor under 180.

Below that the lower the temperature, the better the motor will finish the race (less fade).

As long as keep the motor under 180 no damage will happen.

For example, in hot summer in a touring car with track temps in the 150 range, motor temp can get to 180 easily so a fan is a must. Racing indoor offroad depending on the layout and class, our team guys run the motor 130-165.
In all 1 cell applications we try to keep the motor below 150. Anything above that fades hard at the end of a run and there is not enough voltage to push the motor.

I hope this helps
Thanks

24K
 

That temp is good a little hotter wouldn't hurt none! Not sure if your indoors or out and the outside temp but my motor temps of my motor's run around 170-175* my track is short and technical indoors temp around 70-75*. Winter time here in Colorado. My gearing is around 6.19:1 (72/30) on my KF2 6 minute run's no fan and 30* timing.

It's Revtech.

I hate to say it, but I think you bought the wrong motor. You should be using the 24K. I use the 24k in my 2wd, ST, and SCT. I had the 24ko and promptly replaced it with the regular 24k. I thought the same thing that the motor was a dog. I couldn't gear nor time it high enough to keep up with my D41s. There was also some very large noticeable power fade around the four minute mark.

I'm loving the 24k and even upgraded my buggy and truck to the certified version of the 24k. It's a beast of a motor! I also run a standard 24k 13.5 in SCT and I get a lot of people question the motor I use once they see how fast it is.

The 24k is leaps and bounds faster than the previous D4.

I had better luck w/ the ko in 13.5 SCT... the k was lacking in power before the end of a race.. the ko is strong thru the entire race. They use the same rotor the blank is different, how it handles heat.. the KO can take more heat w/o washing. All rotors are not created equal nor motors... and tbh my maxilla 17.5 which also uses the same rotor is faster and better than the 17.5k I tried. Again not all motors/rotors are created equal so from motor to motor person to person results can very.

whats the problem with running a 24k outdoors?......with the large openings....i heard that it is not recommened...i think thats a bunch of bs....anybody else hear anything about this?

Nope. I ran it outside with no issues.

You are correct this is BS.

What is the best motor for a sc5m the 24k or the Ko in 17.5 and what gearing. Thanks for any help

You wanna get the KO for a Sct or Stadium truck. I'm not sure about AE gearing but I use 75 / 23 w/ 58 degree on my 22sct..

Timing
 

I don't run either but that timing is way to much! Trinity recommends no more than 50*

The timing on my motor was recommend by a trinity team driver. I haven't had an issue with overheating or motor fading..

Mine even came from the factory at over 50* timing. But no clogging and didn't overheat. I think people should so more testing and find out what works for them.

all my hand built certified motors have came with timing over 50. A couple at 60.

Who told you that? I have several Trinity D4s and all are tuned to 50 or above. I have returned 2 to Trinity for repair and they both came back at 55*. I talked to Kevin Abbott from Trinity about my motors and he stated the D4 1S came alive at 50 and above.

I have tuned my motors for maximum rpm/kv vs. amp draw and they all come at around 50+. They never get hot (120-140 degrees after 10 min run)

You may think I am attacking you I am not, but if you refer to the D4 1S and 17.5 motor strings you will see what I am talking about.

I have a 24k and I have yet to place it on my motor checker but the end bell is set to 55* from Trinity.
