Hi, can I use a Spektrum Avian 80A ESC with this motor? Please advise / many thanks in advance!
Peter Kuthy / 21st August 2021

Yes, that would work. These are 56 Amp draw, so less than the 80A your ESC can supply

Ben @ Wheelspin Models
Is this comparable to E flight motor 60 (M-EFLM4060B ) 470Kv out runner
