I only race onroad. I owned a losi 22 for a couple of weeks, but decided offroad doesn't do it for me. I was running a tekin RS Pro with a duo3 motor, but it was an open class. I was using a 5.5
For blinky spec, I'm guessing the motor spec is 17.5??
I'd probably use a Tekin RS Pro and a Trinity ReVtech or D3.5 motor, mainly because I already own these items
(a regular Tekin RS would do fine for this, I just have a Pro though)
In blinky TC, the 2 motors I just mentioned are top notch. Other great choices would be Reedy sonic, Thunderpower, Team Powers and I'm sure there are several others I'm forgetting. I don't imagine it would be much different for which motors perform well in blinky spec offroad classes.
Any of the ESCs on that list I posted should give similar overall power output, but the feel can be different between them.
