It's great on 6s, 8s I brake things!, mainly axel shaft and the speeds are insane!..
The good news is the Neu loves it!, never gets above 140ish degrees MetalMan and I have temped it every time we go out and it's always the same Motor is 140, esc (MGM) is 120 ish.. and my gearing is 52 / 24 for what it’s worth.. and it’s polished! So that got to add another 5 hps (easy!)
