Thanks sir.. I need a 10.5

Whoa, looks like quite a difference. How much track time on that D4?

Did you re-program the ESC between each motor?

Looks like you had a current limiter on the D4 and none on the 24K.

Nonetheless, I've got my 24KO on order.

D4 has probably 3 race nights on it. Only about a month old. No limiter on it at all and all settings were the same including ESC. Nothing reprogrammed.

Thanks for the info likea45

Yes thank you.

My 10.5t 24k is ordered.

In time for 16th race.

Then next is the gen3 10.5t

On the 23th. Then sell the other one that don't work for me..

What's the difference between 17.5K and the 17.5KO extreme? The KO states its for high loads, does it mean it's high RPM (lower pinion)?

from descriptions on Amain...

The 24KO features a bigger blank with more material in the stator. This makes it harder to heat soak the stator, and able to handle more timing and higher gearing. These qualities make the 24KO a better choice for high load applications such as any boosted class, heavier vehicles and short tracks.

The 24K features a smaller blank with less material in the stator that produces more power than the 24KO, but is easier to heatsoak. This motor is faster than the KO initially, but depending on gearing, timing and load it could fall off more at the end of the run when compared to the KO. Because of this, the standard 24K is recommended for blinky applications.

The K is a Short Stack (9g lighter), more RPM = D4 1S
The KO is a Standard Stack (standard weight) more torque. = D4

Info.

I track tested my 24KO today and I have to say I'm very disappointed. I choose the KO because it is suggested for short tracks, heavy vehicles (which mine is not), and high loads. My track is small to medium size with lots of turns and several doubles and a couple triples all clearable in 17.5.

Before the track I had it in my buggy driving up and down the street and it had very high RPMs according to my RSX logging feature. It felt decent in the street. However, the track was another story. The 24KO felt gutless and after about four minutes I could feel the power begin to fade as I watched it struggle to clear a double triple that my D4 1s makes with little to no trouble. I tried several changes such as varying timing anywhere to mid 40s as high as mid 60s and gearing from 71/31 to 78/28. All to no avail.

Maybe I should have gotten the non-O. Possible dud?

if you put it in a buggy, you should have gone with the 24K from everything i've read. 24KO for ST or SC.

Call trinity man. See what they can do.. Going to try out the 10.5t today

the 24k motors won both sct and buggy 17.5 at our regional winter series race last weekend, its the OHKY II and it had about 200 entries and stacked fields in both classes so I would say they performed very well.
