A lot of people think they're unreliable, I've heard about a number of problems. but I've also heard that those problems are due to inexperience and/or poor setup understanding.

The only thing I can say with any certainty is that when I asked an acquaintance who races micro nitro class with me, and also buggies, he said his eight has had no problems whatsoever.

Take from that what you will. 46u, my friend said he had no problems with the servos, maybe he identified the problem himself and fixed it himself, I dunno, but anyway, he likes it.
