Considering the cost is comparable to other mid/high end ESC's, its like you are getting the Rx for free, so from a cost perspective, its a great deal. Also, from a cost/failure point of view, no difference then any other ESC failing.

I ran one in a 4wd buggy, also have used a non-plus in various on road applications, all worked well, super easy to adjust via the Tx.

One thing to consider, I do not think the Plus is ROAR legal for stock blinky racing, and never will be I suspect. With the non plus you need to use a 471(no SSL) in order to be legal.
