yes, I know. Already running the motor on iX8 esc, it is awesome. But as you say, I have to by really careful on throttle. More powerful than castle 1406+SV3 I had before (and much much better quality+smoothness, control) , on 3s even more than lrp 4.5t octawind I had too. But I got used to speed, I like that feeling of power, of course I have to limit it on the track, but off the track, I enjoy it
