I picked up an Activ8 V2/HD8 1900kv combo a few months back for my EB48 to replace the RX8 I was using, after seeing that Novak had pictures of it mounted in one. I've been really pleased with the performance, but it was just too tight between the motor and servo.

I've moved it over to my SCT410 running a Hobbywing 4000kv 4-pole and it works great there with a lot more room.

I like the esc, just wish it was a bit smaller.
