Powerful and smooth on 3s
Bought from Amazon Warehouse for $31 and the original seal on the box had never been broken so motor was brand new. Bought as a replacement for an Onyx 4000kv that I’d run for over a year but finally sheared off the motor shaft on a high speed run in my ECX Brutus. I had no complaints on the Onyx but it’s obviously recently been discontinued so I figured I’d try the Spektrum offering and it seems to be a good upgrade from my Onyx. Motor is more powerful and has zero cogging whatsoever. I’m definitely happy I went with the Spektrum over a similarly priced no name unit. The Spektrum is definitely full of bald eagles and looking forward to a full send speed run to see just how much faster it is than my Onyx motor.
