Correct. Columbia Illinois. But I'll buy one. I'm looking for a xlx2 as well. I enjoy my mmx8s in the kraton. And would like to have a spare esc around. Since I only use castle stuff now.

I've been running tp5660 1460kv 56×92 with 32/50 gearing on 4s behind MAX8 no problems...probly faster on 4s than stock mojave on 6s.32t is my smallest 8mm gear I got.tried 6s an it was cutting out.with huge mojave lol.geared to the moon an ridiculous torque.

 

[Jordan10R]

So this is what u would pick for speed running now. Over the 1650 ?

From the looks of it,ya..at 46×101mm 816 grams it in a 1/6 class of its own.2400kv an 90000rpms is unlike any big can motors out.keeping it cool on 8s could be a problem. Also lots of amp draw I imagine it pulls.

Yea the one it kept cutting out and the other he hit 180 on the 2 videos I watched. But I can't remember if they said what gearing they where running. But I j/w because I was going to buy a 1650 after Christmas for my infraction but looks like I'll be getting this.

This motor should push the big wigs into the 190s easy.razs 180 seamed like a shorter,not 100% pass to me. This is major for speedrunning

 

[jondilly1974]

I’m going to wait this one out. I’ve got enough big block TP motors to burn up first

 

[LibertyMKiii]

The 90k rpm max tells me they did some serious development on the rotor. I am going to assume it has a metal sleeve like the TP CM motors do.
I like the idea, but so many people are going to try Limitless 34/27 gearing and fry their motors.

A higher KV like this really needs lower gearing. Something like 39t spur and 21t pinon. (for 130+mph speeds)

Yeah I hope everyone is reading the warning on this!
